中文摘要 绿色基础设施（GI）的网络化构建，是解决城市化进程中生态斑块破碎化的重要举措。文章以长沙市为研究对象，运用形态学空间格局分析（MSPA）识别现状绿色基础设施要素，依据景观连通性对GI网络中心分级；通过景观格局指数评价现状GI网络格局，结合自然、人类活动因素构建生态阻力面；采用最小累积阻力模型（MCR）与重力模型构建连接廊道，并提取生态节点。结果表明:一级网络中心分布于长沙市的西南部、北部；中部生态阻力较大，不利于网络中心的连接，通过多级连接廊道的构建有效地连接GI网络中心；生态节点可提高较长廊道、阻力值较大区域的连通性，从而构建起多层级的GI网络，为城市绿色空间的建设提供参考。

英文摘要 The construction of green infrastructure (GI) network is an important approach to solving the fragmentation of ecological patches in the process of urbanization. Taking Changsha City as a case, this paper uses morphological spatial pattern analysis (MSPA) to identify the elements of current green infrastructure, and classifies the GI network centers according to the landscape connectivity. The GI network pattern is evaluated using landscape pattern index, and ecological resistance surface is constructed by combining natural and human activities. The minimum cumulative resistance model (MCR) and gravity model are used to construct the connecting corridor, and the ecological nodes are extracted. The results show that the first-level network centers are distributed in the southwest and north of Changsha. In the middle, the ecological resistance is large, which is not conducive to the connection of the network centers. The construction of multi-level connection corridors can effectively make the GI network centers connected, and the ecological nodes can improve the connectivity of the long corridors and areas with large resistance values, so as to build a multi-level GI network. This provides reference for the construction of urban green space.
