How do you design, create and maintain the surrounding wetlands, knowing that man-made wet woodland is very rare and transitionalby nature? How do you ensurethat the habitat being created remains viable and sustainable in the long-term? Atkins’engineers of the wetlands and river edges on the London 2012 Olympic Park were tasked with fi nding answers to all of these questions.Covering more than 246 hectares of formerly derelict industrial land, London’s new Olympic Park for the London 2012 Olympic and Paralympic Games is one ofEurope’s biggest-ever urban greening projects. Rivers and wetlands are at the heart of the vision for the new park, which lies in east London’s Lower Lee Valley. Th e landscape that’s now emerging will provide a backdrop for the main action of theLondon 2012 Games.As river edge and wetland engineers for the project, Atkins has played a critical role in turning the vision into reality. Atkins’remit includes design of the soft river edges and wetlands, including riverbank restoration and bioengineering.The transformation is unprecedented. More than 8km of riverbanks have been restored as part of the project; in tandem with this, 2 hectares of reed beds and ponds have been created, along with 9,000 square meters of rare wet woodland(Fig.01).The challenge was about getting people both visual and physical access down to the river-to actually make the rivers more accessible and more open, and therefore the centerpiece of the Park.Mike Vaughan heads up Atkins' multidisciplinary design team, which includes river engineers, geomorphologists and ecologists. “The idea was to open up the river corridor by making the steep sl opes that line the river fl att er,”explains Mike. “By dropping the slopes, we’ve brought the river into the park and made it much more accessible-people can get close to the river and see what’s going on there.”Gett ing the riverbank geometry just right was a delicate balancing act. Too steep, and the banks would need costly artifi cial reinforcement; too shallow, and they would start to eat into valuable space on the site. An optimum slope of 1 in 2.5-about 22 degrees- was chosen. The space occupied by river bank was restricted by the need to convey fl oodwater and the location of terrestrial landscape and infrastructure. As such, the banks were over-steepened using two approaches. Firstly, where possible, the riverbanks were terraced using coir rolls and timber stakes. In other locations, where only a 70 degree bank was possible, a reinforced detail was used, providing layers of geo-grid and steel mesh cages, faced with a riverside turf.Today, with the new landscape rapidly taking shape, it’s easy to forget how the Lee Valley used to look. Until the Olympic Delivery Authority (ODA) took possession of the site in 2006, many of the river channels that criss-cross the site were clogged with invasive weeds, along with the predictable detritus of urban decay: abandoned shopping trolleys and car tires.Th e Lee Valley’s neglected river network wasn’t only an eyesore, but also an obstacle-a gulf separating Hackney and Tower Hamlets in the west from Waltham Forest and Newham in the east.Now, the revitalized waterways-and the new crossings spanning them-will be vital not only during the Games, but also aft er 2012. Th ey are an integral part of the legacy solution, stitching the new Park and its waterways into the wider fabric of east London.1 Bringing Habitats back to LifeMaking the most of the site’s rivers and natural features to create sustainable habitats is a key part of the Olympic Delivery Authority’s vision for the Olympic Park. But the process of transforming the park’s rivers from weed and rubbish-infested gulches into pristine watercourses has been long and tough.For Atkins, that process started with developing an intimate understanding of the labyrinth of waterways and channels that wind their way through the site. Flows and velocities were measured at diff erent points over a period of time, with data used to construct a detailed hydraulic model to predict flood risk. That’s of critical importance, because Atkins had responsibility for everything up to a contour of 4 meters above ordnance datum (sea level) on the site.A full flood risk assessment was undertaken at environmental impact assessment stage. Atkins undertook analyses of the risk of fl ooding caused by frequent rainfall, taking into account the automated regulation of water levels in the impounded reaches and the impact of tidal lockout. The modeling exercise was made considerably more complicated by the impoundment of the river system during the course of 2008; in effect, this eliminated thedirect tidal infl uence of the Th ames. But its indirect infl uence is still felt. “When the tide comes in on the Th ames, it stops water fl owing out of the River Lee,”explains Mike Vaughan. “So the river levels fl uctuate by an average of 400mm a day.”Atkins’modeling calculations correctly predicted th is phenomenon, and also the increased risk of flooding. “These discoveries led to some changes in the landscaping profile,”says Mike. “The riverside paths have been raised by up to a meter and the profile of the wetlands was also raised, as maintaining cor rect water levels is critical to their survival.”Sustainable drainage techniques have also been used across the Park. In the landscape areas, porous strips have been used in the concourse, feeding into bioswales which drain down into the riverside ponds. Surface conveyance, underground pipes and storage features have also been utilized(Fig.02).The first step in the river restoration process was to “lay back”the banks, many of which were precipitously steep. This re-profiling was necessary because much of the surrounding land was “made”ground, the result of centuries of tipping that had raised the ground level by as much as 10 meters in places. The cocktail of materials on the banks included rubble, glass, animal bones and, more recently, wartime demolition materials from London’s east end.Another challenge facing the Atkins team was the prevalence of invasive weeds. These included Himalayan balsam, Japanese knotweed and giant hogweed. All are fast-growing non-native plants introduced to Britain in the 19th century as gardencuriosities; all have prospered on the wrong side of the garden wall.Invasive species are bad news for riverbanks. They reproduceand grow with prodigious speed, driving out native plant species. And they’re highly resilient. Knotweed ca n force its way through solid concrete, while giant hogweed contains furocoumarins, sun-activated toxins that can cause skin ulceration. Elimination was a priority –soil was treated throughout the site and the banks stripped of all remaining vegetation.In addition, Atkins was responsible for ensuring the protection of the existing fl ora and fauna on the site. Phase one habitat surveys were undertaken as part of the environmental impact assessment in 2006, including bird and fi sh surveys. A major translocation of species was undertaken to suitable receptor sites including a specially-created 1 hectare site just outside the Park. Atkins translocated 330 commonlizards, 100 toads and 4,000 smooth newts. In order to protect the flora on the site, Atkins maint ained a ‘permit to clear’system for contractors, and specifi ed safeguarded habitat areas that were not to be touched including areas of sycamore trees.2 Choosing Plants to PlantAtkins is responsible for the final look of the riverbanks and wetlands-and deciding what to re- plant presented a challenge. With banks now bare, new planting would have to fulfi ll not only ecological and aesthetic demands-they’d be expected to be in bloom for the Olympic Games-but engineering imperatives too.The Atkins design team chose bioengineering techniques, rather than culverting and hard engineering, for the project. That means protecting and consolidating riverbanks by using vegetation and natural products instead of concrete. Choosing the right species with the right root systems would be critical to protect the banks from erosion.An added challenge was that the river network is semi-tidal. The twice-daily rise and fall of around 400mm had the potential to play havoc with new planting, and the river’s high sediment loads threatened to smother anything planted from seed or plugs. “We don’t actually have a natural river system,”notes Mike. “Plants don’t cop well in those conditions.”To fi nd out which plants would fare best-and to establish the most eff ective planting methods -Atkins conducted a unique riverbank planting trial along a 50-metre stretch of the Lee in the Olympic Park.“We trialled plants of different elevations and different installation techniques. These were monitored over a year,”says Ian Morrissey, senior environmental scientist with Atkins. “That’s really helped to inform exactly what species we should plant and where.”The trial revealed that plug plants would be just too vulnerable. But plants pre-grown in coir -coconut fibre matting-resisted being washed away or swamped. Coir has other benefi ts too-it’s easy and quick to install in rolls and pallets two meters long and a meter wide(Fig.03).“Th e mat itself acts like a mulch, so you prevent any weeds growing up through it that might already be within the bank material. But more importantly, when the banks become inundated, you get fine sediment trapped within the coir. Th at helps to bind the roots and feed the plants,”says Ian.3 Banking on Tomorrow’s SeedlingsCreating a sustainable riverbank ecosystem means using native species. So before the banks were scraped back, seed was collected from suitable native aquatic species-a process managed by Atkins -and stored in a seed bank. Some of this seedwas then used by bioengineering and nursery specialists, Salix, who were appointed by the Olympic Delivery Authority to cultivate plants off site in what’s believed to be one of Britain’s biggest-ever nursery contracts.The offsite growing operation was huge and sowing for the project commenced in June 2009, as plants must be a year old and well established in their coir pallets before encountering the tough riverbank environment.Plants for the wet woodlands, including sedges, were raised in more than 7,000 pots at Salix’s nursery on the Gower peninsula, near Swansea. And in Norfolk, the company created a new 16-acre nursery dedicated to the 2012 project(Fig.04). Here, more than 300,000 plants representing some 28 different species, including sedges, common reed, marsh marigolds and yellow fl ag irises, were grown on more than a thousand coir pallets, ready to be transported to London in the following months.During the summer of 2010, the 18,000 square metres of planting were then pieced together like a giant jigsaw. This was a massive logistical challenge. To make it easier, each of the pallets and rolls was tagged. It was vitally important that each one went in exactly the right space so as to avoid cutting and trimming the roots and rhizomes of the plants. The team laid them out in blocks, to a plan, to make sure this didn’t happen.4 Ponds and Wet Woodlands from ScratchWhile the riverbanks of the “Old River Lee”occupied much of the attention ofthe Atkins team, there were also entirely new bodies of water to consider. A fundamental part of the biodiversity of the river edges in the north of the Park lies in three new triangular ponds, off the east bank. Two of these were designed to dry up in thesummer, forming moist grassy hollows. Th e third pond was created to retain water, enabling species such as water lilies and marsh marigold to thrive(Fig.05).Preventing that third pond from drying out -while also ensuring that it did not fl ood along with the River Lee-was a conundrum. Atkins responded by designing a connection between the pond and the river to act as both overfl ow and feed. Flows could be regulated: when the pond level rose too high, water could be drained back into the river; when it started to dry out, a valve could be opened to release river water back into the pond. It sounds simple, but it is believed to be the fi rst of its kind for a habitat feature of this scale.As well as the improved waterways and riverbanks, new wet woodlands will be a notable feature of the Olympic Park. They’re now a rare habitat in the UK, and the ones in the Park are being created from scratch.“It was quite a novel thing to be asked to do,”recalls Atkins’Ian Morrissey. “The challenge was to make sure we had the right water levels within the wetwoodland areas. Atkins was responsible for working out the topographies and the channels, and how they would interact with the river.”Wetlands have a tendency to become dry land eventually, a process that can be slowed down through selecting the right vegetation, careful water level management and maintenance.“The sedge spec ies we selected were chosen because they are quite vigorous so are able to compete well with terrestrial species,”says Ian.Tree species for the wet woodland include willow, alder, birch and the now rare black poplar, points out Atkins’Mike Vaughan: “It’s fantastic for wildlife. You get a lot of invertebrates in there,as well as nesting birds.”Birds, though, can present a challenge, particularly on the freshly planted riverbanks.“There’s a risk of wildfowl grazing our plants when they get on site,”says M ike. To prevent that happening, hundreds of meters of deterrent fencing were erected around new vegetation. That stayed there until spring 2012(Fig.06).5 Beyond the Finishing LineThe transformation of the lower Lee Valley and the creation of the new park, now nearing completion, is remarkable by any standards. Visitors to the Olympic Park –up to 250,000 every day at the peak of the Games –will encounter one of the greenest and most environmentally friendly parks ever to be created for the Olympics.And th e benefits will be felt long after 2012. “We’re pulling that really difficult trick of putting in infrastructure that’s good for the Games, but will work in legacy,”said the ODA's John Hopkins. “This will be a great place to live and work, with rivers and parklands at the heart. Socially, economically and environmentally, there will be a terrifi c legacy-it’s a new landscape powering a new piece of city.”伦敦2012奥林匹克公园滨水景观设计与营造如果在不久的未来，将有数百万人途经这块滨水区域，沿河该如何种植？如果了解到自然界中人造湿林地已十分罕见，该如何设计、创造并维护周边这种湿地环境？该如何长期保持栖息地的活力和可持续性？在伦敦2012奥林匹克公园项目中，来自阿特金斯的工程师们受托负责湿地和河滨地区设计及建设，将会找到所有这些问题的答案。

由于特殊的气候条件，青海春季降水较少，容易形成春旱，而这个时期正是农作物的播种至分蘖期，春旱是影响青海粮食产量丰歉的重要因素之一。

春季降水的多寡、第一场透雨出现的迟早是春季干旱是否发生的关键因子。

1 西宁地区春季第一场透雨时间分布通过统计1961—2015年西宁地区（辖西宁市、大通县、湟源县和湟中县）春季第一场透雨出现的频次（见表1），93%的透雨出现在春季，近一半集中在4月中旬到5月上旬出现，4月前5月后出现第一场透雨的概率各占7%，3月中旬仅出现过一次：2012年3月16日大通降水量为12.5mm，达到第一场透雨标准，是历年最早的一次。

大通、湟中春季降水量偏多，第一场透雨基本都在春季出现，时间也相对偏早，最多频次出现在4月中旬；西宁、湟源最多频次则在5月上旬，西宁春季出现第一场透雨的概率为91%，湟源为85%，西宁2015年第一场≥10mm的降水直到6月19日才出现，仅次于1980年，为第二晚的一年。

外文资料翻译Place-based urban ecology: A century of park planning in SeattleIntroductionSeattle is a city of over half a million residents with approximately 9% of its total area designated as park or open space (US Census 2000). There are currently more than 400 city-owned and maintained parks, including forested areas, boulevards, playfields, playgrounds, and golf courses. Guided by a vision and comprehensive plan for parks developed in 1903 by John C. Olmsted, Seattle has woven an extensive system of park spaces into the fabric of the city. This commitment to parks and open space has persisted throughout the development history of the city. Although the contemporary park landscape is a physical legacy of the 1903 Olmsted plan, shifting political processes, fluctuating economic conditions and evolving cultural ideologies have influenced the implementation of the plan over the past 100 years. More than a century after its initial implementation, the plan continues to be interpreted and applied within the context of a densely settled urban system, where the converging interactions between politics, economics, and park planning culture are in some ways similar, yet inherently distinct from the earliest period of park planning in Seattle.Our research explores the development and influence of park planning in Seattle from 1884 to 2004 within an analytic framework of urban ecology (see Alberti et al. 2003). Within natural science research, urban ecology promotes the re-integration of humans into researching the ecology of urban systems (May 2004; Alberti et al. 2003; Pickett et al. 2001; Grimm et al. 2000). Much of the natural science research has defined urban areas as “ecosystems” without explicitly acknowledging the influence of hum ans on the biophysical landscape (McIntyre et al. 2000). However, as the understanding of ecological processes in urban and urbanizing environments expands, natural scientists are becoming more motivated to perceive urban areas as human dominated systems which function in distinct ways from non-human dominated systems. The growing appreciation among natural scientists for the role of urban social systems in driving urban ecological change facilitated the construction of an urban ecological framework that perceives urban systems as co-evolving human and natural systems (Alberti et al. 2003).The application of an urban ecological framework allows for the detailed study of interactions between human (including political, economic, and cultural) and biophysical (including hydrological, climatological, and terrestrial) conditions as well as resulting patterns of environmental and social change. Urban ecology has been positioned between the humanities and science, with some urban ecologists proposing that humanities become the backbone of rigorous urban ecology research (Alberti et al. 2003). Although, most urban scholars acknowledge the importance of history and culture, few recognize the influence of historical contingencies on the social and ecological patterns that emerge in urban systems. May (2004) explicitly incorporates a humanistic approach into an urban ecological framework, and articulates the influence of historical conditions and cultural practices in the development of an urban area. Building upon her work, we expand this urban ecological framework to incorporate methods of historical analysis for exploring how the interactions between politics, economics, and ideologies have influenced park planning and development over time.Our framework embraces a place-based, historically grounded approach focusing on the relationship between patterns of park development, shifting political arrangements, changing cultural conditions, and fluctuating fiscal resources within park planning. We ask three questions:1. What major political, economic, and cultural processes have influenced park planningin Seattle over the past century;2. How have these processes interacted to produce significant and distinct periods ofpark planning (including acquisition and development) activity; and3. How has the 1903 Olmsted plan persisted and adapted to the shifting processes ofpark planning during this same time.We define the politics of park planning as the relationship between the Seattle Parks and Recreation Department (SPRD), Seattle city elite and local community members engaged in the process of park planning. The economics of park planning refers to private, city, regional,and federal fiscal resources used to acquire, develop, and maintain parks. Park planning culture is viewed as the influence of citywide agendas concerning park acquisition, maintenance and development. Primarily driven by local factors, these three components of park planning are further influenced by scalar economic, political, and cultural conditions. We explore each component individually, while also paying attention to their interactions in order to describe and situate the application of the 1903 Olmsted plan. By incorporating a historic analytic method to Alberti et al’s framework of urban ecology, we are able to identify fluctuations in long-term processes and drivers, which lead to a rich understanding of the evolution of urban systems.Our description of the process of urban park planning and development over 100 years motivates an understanding of cities as ecological systems, where the historical interrelationship between social, economic and political processes has influenced park development in Seattle. We are therefore most concerned with examining the ecological relationships, or network of factors, influencing park acquisition and development over time. By focusing on the drivers, processes and patterns of urban change in relation to parks, we utilize three of the four aspects of Alberti et al’s conceptual framework. The fourth dimension, addressing effects—such as the ecological function of parks and park use patterns—is not part of this historical study.地点为基础的城市生态环境：西雅图一个世纪的公园规划导言西雅图是一个居民人数超过50万、总面积约9%指定为公园或开放空间的城市(US Census 2000)。

Provide the most directly the most abundant source. [Keywords]:The ecosystem building / the view constructThe view design and artNeed not to doubt, the view design is an art, it has inevitable contact with of other art forms.The modern view designs from the first, absorbing abundant form language from the modern art.For look for the designer of the form glossary who can express currentscience,technique and mankind to realize an activity to say, the art provided the most directly the most abundant source doubtless. From the stereoscopic doctrine,surrealism,the style parties,the composing doctrine of modern art earlier period, to later pole Chien's art,wave art, each kind of art current of thought and the art forms all provide and can draw lessons from for the view designer of the art thought and the form language. Today, the concept of[with] art has already taken place very big variety, "beautiful" no longer is the purpose of[with] art and adjudicate an art of standard.The art form pile up one after another, the pure art is gradually misty with the boundary of of the other art door, the artists absorbed the creations skill ofmovie,television,drama,music,building,view...etc., creating such as the media arts,behaviorart,radiation in response to a series of new art form, such as, art, and the earth art etc., but these turn over and give other art professions of from the operator with inspire very greatly.The painting is because of lines,piece the noodles and color of the oneself seem to be is converted into very easily to design some main factors in the plane chart, as a result has been influence the development of[with] the view design, pursue a creative view the designers already to acquire the inspiration of the sub- everlasting from the modern painting.The twenty At the beginning of century, the the stereoscopic parties painter added (the the Pablo Picasso 1881~1973) fully with cloth to the pull to the appear to the change much the in the the appearance of the the gram(the the Georges Braque l 882-1963 yearses) the of several bodies, the appeared what the several standpoints the in the the space see the to fold the to add, Be expressing in two even the result of the fore basic virtues.Their idea has deep but direct influence to the art field.Ex-The from two wars a the down to date, the stereoscopic send the the work the that sends the with super the reality to the the influence the that the the designer has the to keep the on. The set up in 1998 of the the Holland the Amsterdam card the pulls the the sectionsquare(Carraseoplein, the the Adriaan Geuze design), the with lawn, the the asphalt the road noodles the and the the road noodles the top the the dot array the of the the white was the a chemical element, the designing on the the ground the a two the the surrealism the appearance ofthe the ,the plus the the oddity in the a view the of light, voice and the train of the ambulation, make this space had surrealism of mysterious atmosphere.The design thought of the style parties has ever influenced to numerous design realms, its form language has already arrived an important function to the modern building sport.The building imitates the ancients the gram, Anne(the GaBriel Guevrekan l 900-1970 years) completed in 1927 of locate design in the villa courtyard of the French south Hyeres, break the restriction of the narrow and small base to spread the base of the square piece of a ground of brick and the tulip flower terrace demarcation triangle, absorbed the style parties to receive the spirit of Anne in Delhi's painting especially in the design, is made use of a ground well and enter a 3D composition design.Carve to have a close relation with park on the western history, carve to have been the adornment thing in the park but exist, even arrived a modern a society, this tradition reserves still.But the modern carve the substance influence to the view, is along with its oneself some developments just produce.Because a part carve steadily alignment abstraction, the alignment outdoors, extend dimensions and use various natural material, add to near to with the view work more, these two kinds of fusions of arts also naturally the real estate born.The pole Chien's doctrine(Minimalism) is a kind of art that takes simple and direct and several bodies as basic art language to exercise.Most pole Chien's art works make use of several of or organic form, use new comprehensive material, have a strong industrial color.The thought and work of[with] the pole Chien's doctrine not only promoted the earth art produce, but also influenced the two post-war views design.20Half after century leaf, to the variety and the development influence of the view form the biggest art form BE"the earth art" perhaps.The earth art inheritted the abstract simple shape form of[with] the pole Chien's art, and then blended the thought of[with] process art,the concept art, becoming a bridge that the artist sets foot in the view design.The earth art because of it the natural environment is to create place, as a result become the form language that many view designers draw lessons from, in the meantime, the artist also sets foot in the realm of[with] the view design in succession, many works usually are what the views teacher and artist cooperate complete, this also promoted more view with carve two kinds of fusion and the development of artses. An important influence of the earth art to the view design is the idea that brought an art to turn the geography design. The building critic ZHAN KE4 SI(the Charles Jencks i 939~) whom the year construct locates a Scotch southwest department a Dumfriesshire private garden, being turn with the abstruse and exquisite design thought and the art of the geography processing but call.The thought and manifestation of the modern art have profound influence to the view design, making the view design of the thought and means is more abundant.Different from pure art BE, the view design faces the challenge of[with] more complicated social problem and usage problem, view the designer can't take no cognizance these but sink to immerse in own art world.But since we can comprehend"beautiful" Be not the standard that adjudicates an art any more, we should can also comprehend a view no longer is mean"such as painting", the view can become a certain art to thought of carry a body, it can express a diverse form, so we can also have another a to tolerate for some views works that we don't comprehend very.The view design and ecosystemThe ecosystem of the view isn't a fresh concept.Have no 沦to construct in how of the environment, the views are all and abiogenesis close contact, this relation problem that involves to the view and the mankind and the nature by all means, just the environment problem of today is more outstanding, being subjected to a concern more, so the ecosystem becomes one of the most fashionable topics apparently.The ecosystem doctrine the wave tide that rolls up a world urges the top of the angle of view that people stand on science to re- examine the view profession, view the designers also start getting up own mission and the whole Earth ecosystem system contact.Now, at the view profession a little bit flourishing nations, the design of[with] the ecosystem doctrine already is not stay around the 沦text and the diagram paper up of empty talk also Be not the experiment of a handful of designers any more, the ecosystem doctrine has already become a view a designer internality of with hypostatic consideration.Respect the nature development process, initiate energy and material of circulating make use of and place of the ego maintain, developping the processing technique that can keep on etc. the thought pierce through to design and construct in the view with management of always.In the design pursue ecosystem already with pursue the function and the form the equal importance, after sometimes even surmounting both, occupied initial position.The ecology thought of lead to go into, make the view design of the thought and method took place a graveness a change, also influencing to even change the image of the view consumedly.The view design no longer stays around the narrow and small world of[with] the garden design, it starts get involved the more extensive environment design realm.Maintain by one's own to the respect of the place ecosystem development process,to the circulating exploitation of the material energy and to the place with can keep on a processing to initiate technically, the body is now strong ecosystem principle.Though see from the outside idea, most views or many or littlely body now green, green of not necessarily is an ecosystem of, cost a great deal of manpower material resources and financial power then can become and keep the view of[with] result, isn't a "green" of the ecosystem meaning. Design medium should make use of the plant of the hometown more, the natural rebirth that respects a place plants a quilt.The nature has it to turn into with the more recent regulation, seeing from the angle of the ecosystem, the natural cluster falls to fall to have vitality more healthily and more than the artificials. Some designers know this, they make use of the address a top original nature to plant a quilt well perhaps in the design, or build up a frame, providing a condition for the natural reborn process, this is also a kind of body that the exertive natural system can move sex now.Society,art,ecosystem balanceThe art,function and science are three targets that the modern view design pursue.After pass by the baptism of the modernism, the function doctrine has become the widespread standardof[with] the view design.However lay particular emphasis on function excessively, the feature of the view sinks unavoidably in mild.The view wants to develop continuously, the art and science became the direction of the breakthrough.The thought and skill of the modern art for promotes the art that the modern view design to have very your work to use, also make the view design is more abundant.The ecosystem doctrine thought and principle that represent science seep through the view design medium, and become the instruction thought of[with] design, expressing a view adesigner to have already been aware of an own technique should bring into the whole Earth ecosystem system.The development of the view is and develop of society close contact.The progressthat the society development,social culture of the economy realize, promote the development of the view business and design realm to expand continuously.The view of today involves to people the square aspect noodles of the life, modern view is for the sake of the person's usage.Turn over, the view has already exceeded historical and any period perhaps tothe positive effect of the society.城市与景观空间环境设计勒·可布西埃著摘要毋庸置疑，景观设计是一门艺术，它与其他艺术形式之间有着必然的联系。
