扬州市中心城区绿地空间格局优化策略研究
|
摘要
以扬州市中心城区为例,探寻可持续发展模式下的网络化绿地布局研究,建立绿地之间的相互连接,与向城市各功能领域的渗透,保护现存的绿色基础、恢复受损单元、构建完整的绿地生态网络,达到绿地空间格局效益的最大化。基于连接度采用最小费用模型,探寻潜在生态廊道;基于渗透度,划定生境斑块并在Arc GIS中对斑块3个等级进行缓冲分析,加强扬州市中心城区内核心区域的生境保护;基于密度运用可达性分析检验规划绿地的合理性。
Taking Yangzhou downtown area as an example, this paper showes the exploration of networked green space layout with the mode of sustainable development, establishment of the interconnection between green space and infiltration into various functional areas of the city, protections of the existing green foundation, restorations of damaged units and constructions of complete green ecological network, and the achievements of maximum efficiency of spatial pattern of green space. Based on the degree of connectivity, the minimum cost model was used to explore potential ecological corridors. Based on the permeability, the habitat patches were delineated and three levels of the patch were analyzed in Arc GIS to strengthen the habitat protection in the core area of downtown Yangzhou. Based on the density, analysis of accessibility was used to test the rationality of planning of green space.
