摘　　要：中国国土空间发展正经历着一系列变革。城市边缘区的绿色空间体系作为城市与乡村之间过渡地带的自然资源要素,不仅承担着区域居民日常休闲的功能,还具有连续城乡生态系统、调控环境韧性能力等多重功能。以南京主城边缘带绿色空间景观系统为例,运用社会网络分析方法对南京绿色空间系统进行评估。系统评价从个体、局部和整体3个空间尺度展开。个体对每个景观斑块的中心性进行计算得到整个系统的核心要素,局部考察景观系统的层级结构,整体则从系统完备性和结构稳定性出发进行综合评估。通过对系统3个不同空间尺度的分析与评估,探索城市边缘区绿色空间健康发展的有效途径。The development of territorial space is undergoing a series of changes. As a natural resource element in the transition zone between the city and the countryside, the green space system in the urban fringe area not only undertakes the daily leisure function of regional residents, but also has a continuous urban-rural ecosystem and regulates environmental resilience. This paper takes the green space landscape system on the fringe of the main city of Nanjing as an example, combines the theory of landscape ecology and connectivity, and uses the social network analysis method to evaluate the green space system in Nanjing. Systematic evaluation is carried out from three spatial scales: individual, part, and whole. The individual is to calculate the centrality of each landscape patch to get the core element of the entire system, the part examines the hierarchical structure, subgroup structure and internal and external relations of the subgroup structure of the landscape system, and the overall from the system completeness and structural stability. Through the analysis of the three diferent spatial scales of the system, the optimal area for the development of landscape ecology in the fringe of the main city of Nanjing is proposed, and efective ways of healthy development of green space in the fringe of the city are explored.
