    摘要:面对日益复杂的人地关系,以往凭经验决策的规划手段已暴露出多种不足,城市规划需要加强科学分析,强调设计与科学的结合。形成了面向城市景观生态安全的地理设计流程与方法,以某快速城市化的中等城市为例,通过综合生态敏感性评价构建城市景观生态安全格局,识别出构建生态格局的关键节点,可为城市规划建设提供依据。提出的地理设计方法的特点为:1)地理科学与规划设计的结合;2)多方利益的公众参与规划。

    Abstract:This study introduces a study of GeoDesign for urban landscape ecological security. Ecological sensitivity is assessed systematically by integrating water resources, geological hazards, green land, bio-diversity and ecological resources. The weight of each factor is determined by local residents, geographers and planners, and an overlay of the five factors is performed in a GIS. Based on the sensitivity map and the concept of geodesign, the areas that are most ecologically fragile and therefore need future attention for restoration are identified. It is concluded that the GeoDesign methodology can be useful for improving the overall land use and the harmony between human and land.
