The practice and theory of Landscape Architecture
景观规划设计理论
【1】Landscape Architecture involves the five major components:They are natural process，human factors，methodology，technology，and values，whatever the scale or emphasis of operation，these five components are consistently relevant.Social and nature factors clearly permeate every facet of a profession that is concerned with people and land. Problem solving，planning，and design methods apply at all scales.Good judgment is consistently required.
风景园林设计包含五个主要方面:自然进程、社会进程、方法论、技术、价值观,无论规模尺度或运作的重点各不相同,这五个要素一贯是相关的。社会因素和自然因素的因子充斥着这个关系到人与土地的领域的方方面面。解决问题,规划、设计方法都会用到所有的尺度。正确的判断判断是一贯必须的。
【2】Consider how natural factors data are relevant to both planning and design.At the regional scale，the impact of development or change in use on a landscape must be known and evaluated before a policy to allow such action is set.An inventory of the natural factors，including geology，soils，hydrology，topography，climate，vegetation and wildlife，and the ecological relationships between them is fundamental to and understanding of the ecosystem to which change is contemplated.Equally important is an analysis of visual quality .Land use policy can thus be made on the basis of the known vulnerability of resistance of the landscape.In other circumstances the natural processes which add up to a given landscape at a give moment in its evolution may，as at Grand Canyon and other unique places，be considered a resource to be preserved，protected，and managed as a public trust.On a smaller scale，soil and geological conditions may be critical in the determination of the cost and the form of building foundations: where it is most suitable to build and where it is not.Sun，wind，and rain are important factors of design where the development of comfort zones for human activity or the growth of plants is a primary objective.Thus，in many ways natural factors influence land use，site planning，and detailer design.
自然因素的考虑与规划和设计都有关系。在区域尺度上，关于利用方面的开发变化的影响，在政策制定之前，必须了解和评估景观的脆弱性和敏感性。详细的自然因素,包括地质的、土壤的、水文的、地形地貌的、气候的、植被的和野生动物的、以及它们之间的生态关系是理解它将要改变的生态系统的基础。同样重要的是视觉质量的分析。土地利用政策的基础是由于了解到景观的脆弱性和抗损性的基础上建立的。在某些发展进化的过程中，一些在特定的时刻作用到特定的景观的自然进程会产生一些公共资源,比如科罗拉多大峡谷，让我们后人去保护它和管理它。在小尺度上，土壤和地质条件是决定建筑的成本和建筑基础形态的关键要素——哪里适宜建立以及哪里不适宜。设计是为人类发展活动找到适宜的空间或者以植物的生长为主要目标，因此，阳光,风和雨是设计最重要的要素。因此,场地和区域的自然要素在景观规划和设计的许多过程当中相互作用。
【3】The social factors apply equally at various scales.In site planning and landscape design，cultural variation in the use and appreciation of open space and parks and the physical and social needs of the young and old are some of the many variables to be considered in a design process that aims to be responsive to social values and human needs.In decisions relates to appropriation of landscape for recreation and aesthetic value people’s perception of t he environment and the
