城市景观设计中的生态规划Ecological planning in the urban landscape design Abstract: This article discusses the urban landscape from the relation of the following three concepts: the landscape, the city and the ecology. This paper mainly discusses how the landscape influences the city's living environment.The landscape is a stigma in the land, which is of the relationship between human and human, between man and nature. There exists some subtle relationship among landscape, city and humanized design.key word：Urban landscape、Living environment、HumanizationI. City and The Landscape(1) Overview of Landscape DesignLandscape design, first, is a people's thinking activity, performed as an art activity.Diversified thoughts formed complex diverse landscape art style. Contemporary landscape design apparently see is the diversity of the landscape forms,in fact its essence is to keep the closing up to the natural order system, reflected the more respect for human beings, more in-depth perspective of the nature of human's reality and need, not to try to conquer the nature.it is not even imitating natural, but produce a sense of belonging. Landscape is not only a phenomenon but the human visual scene. So the earliest landscape implications is actually city scene. Landscape design and creation is actually to build the city.(2) The Relationship Between Landscape and UrbanCity is a product of human social, economic and cultural development, and the most complex type. It is vulnerable to the artificial and natural environmental conditions of interference. In recent decades, with worldwide the acceleration of urbanization, the urban population intensive, heavy traffic, resource shortage, environment pollution and ecology deterioration has become the focus of attention of the human society. In the current environment condition in our country, the problem is very serious. and in some urban areas, the pollution has quite serious, and greatly influenced and restricts the sustainable development of the city.Landscape is the relationship between man and man, man and nature. This is, in fact, a kind of human living process. Living process is actually with the powers of nature and the interaction process, in order to obtain harmonious process. The landscape is the result of human life in order to survive and to adapt the natural. At the same time, the living process is also a process of establishning harmonious coexistence. Therefore, as a colony landscape, it is a stigma of the relationship between man and nature.II the city landscape planning and design(1) city landscape elementsThe urban landscape elements include natural landscape and artificial landscape. Among them, the natural landscape is mainly refers to the natural scenery, such as size hills, ancient and famous trees, stone, rivers, lakes, oceans, etc. Artificiallandscape are the main cultural relics, cultural site, the botanical garden afforestation, art sketch, trade fairs, build structure, square, etc. These landscape elements must offer a lot of examples for creating high quality of the urban space environment. But for a unique urban landscape, you must put all sorts of landscape elements in the system organization,and create an orderly space form.(2)the urban landscape in the planningThe city is an organic whole, which is composed with material, economy, culture, and society.To improve the urban environment is a common voice.The key of the urban landscape design is to strengthen urban design ideas, strengthen urban design work. and blend urban design thought into the stages of urban planning. The overall urban planning in the city landscape planning is not to abandon the traditional garden, green space planning, but the extension and development of it.Both are no conflict, but also cannot be equal.In landscape planningof city planning, we should first analysis the urban landscape resources structure, fully exploit landscape elements which can reflect the characteristics of urban.Consider carefully for the formation of the system of urban landscape.III ecological planning and urban landscape (1) the relationship of urban landscape and ecological planning Landscape ecology is a newly emerged cross discipline, the main research space pattern and ecological processes of interaction, its theme is the fork the geography and ecology. It's with the whole landscape as the object, through the material flow, energy flow and information flowing the surface of the earth and value in transmission and exchange, through the biological and the biological and the interaction between human and transformation, the ecological system principle and system research methods of landscape structure and function.the dynamic change of landscape has interaction mechanism, the research of the landscape pattern, optimizing the structure, beautify the reasonable use and the protection, have very strong practicability. Urban ecological system is a natural, economic and social composite artificial ecosystem, it including life system, environment system, with a complex multi-level structure, can be in different approaches of human activity and the mutual relationship between the city and influence. Urban environment planning guidance and coordination as a macro department interests, optimizing the allocation of land resources city, reasonable urban space environment organization the important strategic deployment, must have ecological concept. Only to have the ecological view, to guide the construction of the city in the future to ecological city goal, to establish the harmonious living environment. In recent years, landscape planning in urban landscape features protection and urban environment design is wide used.(2) landscape in the living environment of ecological effectLandscape as a unit of land by different inlaid with obvious visual characteristics of the geographic entities, with the economic, ecological and aesthetic value, the multiple value judgment is landscape planning and management foundation. Landscape planning and design always is to create a pleasant landscape as the center. The appropriate human nature can understand the landscape for more suitable for human survival, reflect ecological civilization living environment, includinglandscape, building economy, prudent sex ecological stability, environmental cleanliness, space crowded index, landscape beautiful degree of content, the current many places for residential area of green, static, beauty, Ann's requirement is the popular expression. Landscape also paid special attention to the spatial relationship landscape elements, such as shape and size,density and capacity, links, and partition, location and of sequence, as their content of material and natural resources as important as quality. As the urban landscape planning should pay attention to arrange the city space pattern, the relative concentration of the open space, the construction space to density alternate with; In artificial environment appeared to nature; Increase the visual landscape diversity; Protect the environment MinGanOu and to promote green space system construction.(3) the urban landscape and ecological planning and design of the fusion of each other.The city landscape and ecological planning design reflects human a new dream, it is accompanied by industrialization and after the arrival of the era of industrial and increasingly clear. Natural and cultural, design of the environment and life environment, beautiful form and ecological functions of real comprehensive fusion, the landscape is no longer a single city of specific land, but let the ablation, to thousands; It will let nature participate in design; Let the natural process with every one according to daily life; Let people to perception, experience and care the natural process and natural design.(4) the city landscape ecological planning the humanized design1. "it is with the person this" design thought Contemporary landscape in meet purpose at the same time, more in-depth perspective on human of the nature of reality and needs. First performance for civilian design direction, application of natural organic materials and elastic curve form rich human life space. Next is the barrier-free design, namely no obstacle, not dangerous thing, no manipulation of the barrier design. Now there have been the elderly, the disabled, from the perspective of the social tendency, barrier-free design ideas began to gain popularity, at the same time for disadvantaged people to carry on the design also is human nature design to overall depth direction development trend. "It is with the person this" the service thoughts still behave in special attention to plant of bright color, smell good plant, pay attention to ZuoJu texture and the intensity of the light. The detail processing of considerate more expression of the concern, such as the only step to shop often caused visual ignored and cause staggered, in order to avoid this kind of circumstance happening, contemporary landscape sites do not be allowed under 3 steps; And as some residential area and square in the bush set mop pool, convenient the district's hygiene and wastewater recycling water. "It is with the person this" the service thoughts in many ways showed, the measure of the standard is human love.1. 1 human landscape design concept is human landscape design is to point to in landscape design activity, pay attention to human needs, in view of the user to the environment of the landscape of a need to spread design, which satisfied the user "physiological and psychological, physical and mental" multi-level needs, embodies the "people-oriented" design thought. Urban public space human landscape design, from the following four aspects to understand:1. 1.1 physical level of care. Human landscape design with functional and the rationality of design into premise condition, pay attention to the physical space reasonable layout and effective use of the function. Public space design should not only make people's psychology and physiology feel comfortable, still should configuration of facilities to meet people's complex activities demand1. The level of caring heart 1.2 Daniel. In construction material form of the space at the same time, the positive psychology advocate for users with the attention that emotion, and then make the person place to form the security, field feeling and belonging.1. 1.3 club will level of care. Emphasizes the concern of human survival environment, the design in the area under the background of urban ecological overall planning and design, to make the resources, energy rationally and effectively using, to achieve the natural, social and economic benefits of the unity of the three.1. 1.4 to a crowd of segmentation close care. Advocate barrier-free design, and try to meet the needs of different people use, and to ensure that the group of mutual influence between activities, let children, old people, disabled people can enjoy outdoor public the fun of life.1. 2 and human landscape design related environmental behavior knowledge the environment behavior is human landscape design, the main research field, pay attention to the environment and people's explicit behavior and the relationship between the interaction, tried to use the psychology of the some basic theory, methods researchers in the city and architecture in activities and to the environment of the response, and the feedback the information can be used to guide the environment construction and renovation. Western psychologist dirk DE Joan to put forward the boundary effect theory. He points out that the edge of space is people like to stay area, also is the space of the growth of the activity area [3]. Like the urban space, the margin of the wood, down the street, and the rain at the awning, awnings, corridor construction sunken place, is people like the place to stay. At the edge of space, and other people or organizations to distance themselves are is better able to observe the space of the eyes and not to be disturbed. "Man seeth" is the person's nature. A large public space are existing "the man seeth" phenomenon: the viewer consciously or unconsciously observation, in the space in front of the all activities. At the same time, some of the people with strong performance desire, in public space in various activities to attract the attention of others, so as to achieve self-fulfillment cheerful. The seemingly simple "man seeth" phenomenon, but can promote space more activities production. For example, for a walk of pedestrians may be busy street performance and to join the ranks of the show attracts, with the strange because the audience is the sight of the activities of the wonderful and short conversation, art lovers of the infection by environmental atmosphere began to sketch activities. Environmental design, according to environmental behavior related knowledge, actively create boundary space provide people stay, rest, the place of talking to facilitate more spaceThe Landscape Urbanism exhibition contained an international survey of public urban spaces by designers including Adriaan Geuze/West 8, Michael Van Valkenburgh,Patrick Schumacher, Alex Wall, and several Barcelona landscape architects (such as Enric Batlle and Joan Roig, who completed Trinitat Cloverleaf Park in a highway intersection for the 1992 Olympics). American exhibitors included Corner and Mathur, Waldheim’s teachers from Penn, Mapillero/ Pollack from New York, Conway-Schulte of Atlanta Olympics fame, and Jason Young/Omar Perez/Georgia Daskalakis/Das: 20 from Detroit. Corner’s premiated but sadly unbuilt Greenport Harborfront, Long Island Project (1997), stood out in this show. His office, Field Operations, proposed creating a sense of urban activity around the annual raising and lower-ing of the town’s ancient sailing ship Stella Maris up and down a newly created slip, with a historic, children’s carousel housed in an adjacent band shell. Corner envisioned this staged, biannual event as an attractor for peo-ple, the press, and media, who would flock to the town in its off season, inhabiting the newly created commons on the harbor front to watch the ship’s spectacular movements. In the winter, the ship would become a monumental, sculptural presence lit at night in the center of the small port’s commons; in the summer it would return to its accustomed quayside, where its masts would tower above the rooftops. 21Corner’s project in the Landscape Urbanism exhibition illustrates his concept of a “performative” ur banism based on preparing the setting for programmed and unprogrammed activi-ties on land owned in common. The three projects presented in Stalking Detroit provide further insights into this emerging strategy, and each is paired with a commentary by a landscape architect. 22 The Waldheim and Marli Santos-Munne Studio proposes the most comprehensive of landscape urbanism practices in “Decamping Detroit” (104–122). They advocate a four-stage decommissioning of land from the city’s legal control: “Dislocation” (disconnection of services), then “Erasure” (demolition and jumpstarting the native landscape ecology by dropping appropriate seeds from the air), then “Absorption” (ecological reconstitution of part of the Zone as woods, marshes, and streams), and then “Infiltration” (the recolonization of the landscape with heteropic village-like enclaves). As Corner writes in his commentary, this project “prompts you to reflect on the reversal of the traditional approach to colonization, from building to unbuilding, removal, and erasure” (122). This reversal of normal processes opens the way for a new hybrid urbanism, with dense clusters of activity and the reconstitution of the natural ecology, starting a more ecologically balanced, inner-city urban form in the void.All of Landscape Urbanism’s triumphs so far have been in such marginal and “unbuilt” locations. These range from Victoria Marshall and Steven Tupu’s premiated design for ecological mudflats, dunes, canals, and ramps into the water in the Van Alen East River Competition (1998), which would have simultaneously solved the garbage disposal problem of New York and reconstituted the Brooklyn side of the East River as an ecology to be enjoyed as productive parkland. 23 In the Downside Park, Toronto Competition (2000), Corner, with Stan Allen, competed against Tschumi, Koolhaas (who won), and two other teams, pro-viding a showcase for their “Emerging Ecologies” approach. 24 This was further elaborated in the Field Operations’ design that won first place in the Freshkills Landfill Competition, StatenIsland (2001). Together with Stan Allen (now Dean at Princeton), Corner analyzed the human, natural, and technological systems’ interaction with characteristic aerial precision. Field Operations presented the project as a series of overlaid, CAD-based activity maps and diagrams, that stacked up as in an architect’s layered axonometric section. These layered drawings clearly showed the simultaneous, differentiated activities and support systems planned to occupy the site over time, creating a diagram of the complex settings for activities within the reconstituted ecology of the manmade landfill. 25 In the Freshkills competition, Mathur and da Cunha’s used a similar approach but emphasized the shifting and changing eco-logical systems of the site over time, seeking suitable places for human settlements including residences. In the first conference on Landscape Urban-ism at the University of Pennsylvania in April 2002, Dean Garry Hack (who coauthored Kevin Lynch’s 1984 third edition of Site Planning) questioned the interstitial and small-scale strate-gies of participants (asking, “Hyper-urbanization: Places of Landscape Architecture?”). Mohsen Mostafavi, the Chairman of the AA, delivered the keynote speech, “Landscape as Urban-ism,” showing the Barcelona-style, large-scale, infrastructural work of the first three years of the AA Landscape Urbanism program. 26Dean Hack identified a key problem for landscape urbanists as they face the challenge of adapting to complex urban morphologies beyond that of an Anglo-Saxon village and its commons. Rifle ranges, the spectacle of the “Devil’s Night,” and the “Staging of Vacancy” suggested in Stalking Detroit may prove to be inadequate responses in an age when many Europeans and Americans live in idyllic, landscaped suburbs. Suburbanites are willing to pay a premium to visit staged urban spectacles. These spectacles can take the form of the Palio annual horse race in Siena, a parade on Disneyworld’s Main Street, or a week-end in a city-themed Las Vegas casino like The Venetian, with its simulation of the Grand Canal as a mall on the third floor above the gaming hall. The desire for the city as compressed hustle and bustle in small spaces remains strong. Even in ruined downtown Detroit, small ethnic enclaves like “Greek Town” or “Mexico Town” satisfy this demand, in the midst of the void. Commercial interests like Disney clearly understand how to stage an event and create an urban street spectacle based in a village-like setting. As yet, the dense urban settings of Hong Kong or New York, or even mid-rise urban morphologies like Piano’s eco-logically sensitive Potsdam Platz, Berlin (1994–1998), do not feature as part of this performative urbanism. Stalking Detroit does not begin to deal with the issue of urban morphologies or the emergence of settlement patterns over time. It concentrates on their disappearance and erasure. The problem of this approach is its amnesia and blindness to preexisting structures, urban ecologies, and morphological patterns. A common ground is useless without people to activate it and to surround it, to make it their commons. Housing, however transient or distant, is an essential part of this pattern of relationship, whether connecting to a village green or a suburban mall. With this logic, the International Building Exhibition in Berlin of 1984–1987 sponsored the recolonization of vacant inner-city lots with high-density, low-rise infill blocks in anticipation of the construction of Potsdamer Platz and the demolition of the Berlin Wall. Adaptive reuse, as in the conversion of dockland warehouses ormulti-story factories to lofts and apartments, is another successful strategy that has provided housing and workplaces to activate inner-city areas. These approaches have been slowly applied with some success in other American empowerment zones, such as those in the South Bronx and Harlem. Chicago, also a viciously segregated city, is rising slowly from its ashes; North Michigan Avenue functions as a great urban boulevard, comparable to Fifth Avenue in New York, populated with many strange hybrid skyscraper towers containing malls, department stores, hotels, offices, apartments, and parking lots (a form pioneered there by Skidmore Owings and Merill’s mixed-use Hancock Tower in 1966). Even in Detroit, Henry Ford’s grand-son is rebuilding the Ford River Rouge Plant as a model, hybrid, “green” facility. 27Landscape urbanists are just beginning to battle with the thorny issue of how dense urban forms emerge from landscape and how urban ecologies support performance spaces. The lin-ear organization of the village main street leading to a common space, with its row-house typology and long thin land subdivisions, is one of the oldest global urban patterns, studied by the pioneer urban morphologist Michael R.G. Conzen in the 1930s. 28 Urban morphologists look for the emergence of such characteristic linkages between activity and spatial patterns in human settlements. Such linkages, when repeated over time, form islands of local order structuring the larger pat-terns of global, ecological, and economic flows. 29 The pattern of the town square and approach street is another, more formal example of an urban morphology, focusing on a sin-gle center, setting up the central agora or forum as in a Greek or Roman city grid (and echoed in the courtyard-house typology). The Islamic city, with its irregular cul-de-sac structure, accommodating the topography, emerged as a variation on this classical model, with the mosque, bazaar, school, and baths replacing the forum and temples at the center. 30 Medieval European cities, also with cul-de-sacs, but based on a row-house typology, formed another morphological variation of the classical city, with market halls and cathedrals on the city square. In The Making of the American Landscape (1990), edited by Michael P. Conzen of the University of Chicago, contributors illustrate how the morphology of the city shifted from a dense single center to a “machine city.” This bipolar structure was based on railways creating a regional division between dense center and suburban villa edge (involving the separation of consumption from production, industry from farmland, rich from poor, etc.). In the second phase, the “machine city” of the Modernists (best exemplified by the morphology of Le Corbusier’s Ville Radieuse (1933) with its slab blocks and towers set in park-land) replaced the old, dense Industrial City. With the advent of the automobile, a third morphology emerged in a multi centered pattern and isolated, pavilion, building typologies, a pattern that was further extended by airports on the regional periphery. Joel Garreau identified this as the postmodern “Edge City” morphology of malls, office parks, industrial parks and residential enclaves in 1991. 31In Europe Cedric Price jokingly described these three city morphologies in terms of breakfast dishes. There was the traditional, dense, “hard-boiled egg” city fixed in concentric rings of development within its shell or walls. Then there was the “fried egg” city, where railways stretched the city’s perimeter in linear, accelerated,space-time corridors out into the landscape, resulting in a star shape. Finally there was the postmodern city, the “scrambled egg city,” where everything is distributed evenly in small granules or pavilions across the landscape in a continuous network. Koolhaas and the younger Dutch groups like MVRDV continue this tra-dition of urban, morphological analysis with a light, analogical touch. The organizing group of the 2001 International Conference of Young Planners meeting in Utrecht, for instance, used Price’s metaphors to study the impact of media and communications on the city.32 Franz Oswald , from the ETH Zurich Urban Design program, also examines the “scrambled egg” network analogy in the Synoikos and NEt city Projects . These projects study the distribution of urban morphologies in central Switzerland as layers in a cultural, commercial, industrial and informational matrix within the extreme Alpine topography and its water-sheds. 33 Schumacher, at the AA’s Design Research Laboratory, has also extended his work from Stalking Detroit into an investigation of the role of personal choice in a dynamic, typo-logical, and morphological matrix forming temporary housing structures in the city. 34 His colleagues in the Landscape Urbanism program have also shifted to a more urban orient-tion, studying Venice and its lagoon.This rationalist, morphological and landscape tradition seems to be centered in Venice. Here Bernardo Secchi and Paola Viganò continue the typo-logical analysis begun in the 1930s, but now applied to the voids of the post-modern city-region, the “Reverse City.” Viganò’s La Città Elementare (The Elementary City, 1999; it deserves translation into English) is exemplary of this larger European Landscape Urbanism movement. For Viganò, large landscape infrastructures form the basis for later urbanization. Le Corbusier’s work at the Agora in Chandigarh is exemplary in its monumental manipulation of the terrain, orientation to the regional landscape, and attempt to form an urban space. Xaveer de Geyter Architects’ After Sprawl (2002), with its fifty-by-fifty kilometer “Atlases” of European cities made by various university groups, gives an easily accessible cross section of a wider landscape urbanism and morphological network linked to Venice. In America, Carol Willis in Form Follows Finance (1995) and my colleague at Columbia Urban Design, Brian McGrath, have created a portrait of one building ecology, the sky-scraper, and its typological evolution in the flows of New York in Time formations(2000), viewable at the Sky-scraper Museum website.Activities of generation, the rich visitors sensory experiences2. The design of the sustainable developmentSustainable development principle, it is the ecology point of view, to the city system analysis, and with the minimum the minimal resource consumption to satisfy the requirements of the human, and maintain the harmony of human and the natural environment, guarantee the city several composition system-to protect natural evolution process of open space system and the urban development system balance. People are to landscape 'understanding of the contemporary landscape design and the function to reflect, have been completely out of the traditional gardening activities, the concept of landscape art value unconsciously and ecological value, the function value, cultural value happened relationship, landscape art category than before morepointed to the human is closely linked with the various aspects, become more profound and science. Contemporary landscape also actively use new technology to improve the ecological value. Such as the use of solar energy for square garden, lighting and sound box equipment supply electricity; The surface water "cycle" design concept, collecting rainwater for irrigation and waterscape provides the main resources; Using the principle of the construction of the footway, buoys that environmental protection level a kiss and interesting. And by using water scene drought, landscape water do ecology (ecological wetland), ecological XiGou "half natural change" landscape humanized waterscape design, avoid the manual water scene is the difficulty of the later-period management, but in the water since the net, purifying environment and promote biodiversity play a huge role. Therefore, to experience the landscape will surely is contained to nature and the tradition, to human compatibility.The urban landscape the principles of sustainable development and implementation details:2.1 the efficiency of land use principle for land to the survival of humans is one of the most effective resources, especially in China's large population, land resources are extremely deficient, urbanization rapidly increase background, the reasonable efficient use of land, is that we should consider an important issue. For the city landscape is concerned, how to productive use of the land? Three-dimensional is efficient land use is the most effective means. The urban landscape "three-dimensional to take" ideas contains the following six aspects of meaning. (1) in the limited on land, as much as possible to provide activity places, form the three-dimensional multi-layer activities platform landscape environment. (2) improve afforestation land use efficiency, in the same land, adopt appropriate to niche by, shrubs and trees of co-existence and co-prosperity between three-dimensional planting layout. (3) to solve the good man, for the contradiction in green, the green space and human activity space layout of the interchanges. (4) the up and down or so, all sides three-dimensional view observation, increased the landscape environment the visual image of the visual rate. (5) from the static landscape to dynamic landscape. 6 not only from the traditional technology of modern technology to introduce more (such as crossing bridge, light rail, electric rail, etc), show a colorful three-dimensional space.2.2 energy efficiency principle along with the rapid development of urbanization, China's energy demand is more and more big, the energy gap also more and more big. In recent years, China's major cities have put forward the "light" project, the public area lighting consumption in the great power. For energy efficiency in the understanding, first from the consideration on the energy saving should be not only, and should stand in the higher of the environmental protection high to know, meaning that more extensive, and more far-reaching. (for more than 70% of generating capacity in China at present still by coal, exist for SO2, CO2 and nitric oxide and other harmful gas emissions and coal dust emissions and a series of environmental problems)2.3 plant with an ecological principle city system, the green space system is perfect or。
