| 绿色基础设施网络是加强景观连通性，提升区域生态安全格局的主要手段之一。本文将合肥市作为研究案例，基于 GIS 平台，结合形态学空间格局分析(MSPA)与景观生态学原理，通过识别重组绿色基础设施网络要素，运用 conefor 软件、最小累计阻力模型(MCR)构建绿色基础设施潜在廊道体系，最后结合现有结构性廊道优化潜在廊道体系得到多层级绿色基础设施网络。结果表明：合肥市绿色基础设施网络中心由 50 个大型斑块呈现，巢湖为网络中心中面积最大且连接度最强的；现状区域性连接廊道较少且建设较差，建设较好的连通廊道为南淝河、派河、白石天河、兆河及滁河干渠；整体分布上北部区域网络中心与廊道分布较少。通过分析现状绿色基础设施要素，最终构建起绿色基础设施网络，能够更加科学地为合肥市生态建设提供指导，同时也可为其他区域提供借鉴意义。 |

| Green infrastructure network is one of the main means to enhance landscape connectivity and regional ecological security. This paper takes Hefei as a research case，based on the GIS platform，combined with the principles of morphological spatial pattern analysis (MSPA) and landscape ecology，identifies the elements of the recomposing green infrastructure network，uses the conefor software and the minimum accumulated resistance model (MCR) to construct a potential corridor system for green infrastructure. Finally，the multi-level green infrastructure network was obtained by optimizing the potential corridor system based on the existing structural corridors. The results show that the green infrastructure network in Hefei is represented by 50 large-scale patches，of which Chaohu is the largest and most connected in the network center；There are few regional corridors and poor construction，The relatively well-connected corridors are the Nanzhao River，Paihe River，Baishitianhe River，Zhaohe River，and Weihe Canal；Establish a green infrastructure network by analyzing the current green infrastructure elements，it can provide more scientific guidance for the ecological construction of Hefei City and provide reference for other regions at the same time. |
