生态城市视角下社区绿道的规划设计研究

On the Planning and Design of Community Green-ways in the View of Eco-city

随着我国城市化进程不断加快,城市建设用地日益紧张,城市景观绿地不断被蚕食,生态斑块破碎化现象严重。以社区绿道为平台,作为城市生态空间整合、修复的路径显得具有重要意义。研究以合肥市老城核心区为例,以生态城市思想作为指导,应用GIS空间分析技术,通过对老城核心区斑块资源选择、城市用地景观阻力值计算,得出基于最小景观阻力值的社区绿道网络,改善城市生态质量。

With the acceleration of urbanization in China,the land for urban construction is increasingly is less and less.The urban landscaping green-land is being nibbled and the breaking of ecological patch is more and more serious.Taking the community green-way as a platform,space integration and restoring the urban ecology is of great significance.In the view of the idea of Eco-city,this study takes the core area of Hefei city as an example and applies GIS spatial analysis technology.Through the selection of patch resources in the core area of the older city and calculation of urban landscape resistance value,the community green-way network is got based on minimum landscape resistance value so as to improve urban ecological quality.
