摘　　要：从绿地生态网络的研究现状入手,梳理近年来生态源地识别,生态网络构建、评价及优化的常用方法,发现现状生态网络规划方法存在源地提取主观性较强、忽略结构性景观要素、连通性的分析方法存在局限性、阻力面构建依据不够科学等问题。而基于形态空间格局分析(MSPA)和最小路径法的生态网络构建框架综合了现有结构性景观要素识别、连通性分析以及潜在廊道网络构建等方法,以连通性水平作为网络构建的主要依据,为景观格局分析、生态源地的识别与结构性廊道的提取、斑块廊道重要性的定量分析及阻力面构建等方面存在的问题提供了科学的解决方法。在此基础上提出基于MSPA的生态规划的研究方向,包括MSPA对于尺度敏感性问题的研究、边缘宽度值的设定对于不同物种生态规划的意义、基于MSPA和连通性分析的景观格局时空变化特征评估及基于MSPA的生态网络规划对于不同绿地类型生态建设的差异性指导及可操作性探讨,为基于MSPA的生态网络规划的完善和发展提供新思路。This article starts with recent research on ecological network, summarizing ways to identify ecological sources, establish ecological network, evaluate and optimize ecological network in recent years, realizing that the status quo of ecological network planning has the problem of strong subjectivity in extracting the ecological sources, ignorance of structural landscape elements, limitations existed in landscape connectivity analysis and the establishment of surface resistance based on unscientifc basis. The ecological network planning based on MSPA and minimum path is a combination of the methods of identifying the structural landscape elements, connectivity analysis and potential corridor network building, taking the level of connectivity as the main basis, and providing scientifc solutions to problems on landscape pattern analysis, identifcation of ecological source, extraction of structural corridor, the analysis of importance level of plaques and corridors and the construction of resistance surface. This article puts forward the research direction of ecological network planning based on MSPA, including the study of MSPA sensitivity for scale issue, signifcance of edge width setting to ecological network planning of different species, spatial-temporal changes of landscape structure pattern based on MSPA and connectivity analysis, guidance for ecological construction and operability study of different kinds of greenspace ecological network planning based on MSPA, in order to provide new ideas for consummating and improving ecological network construction based on MSPA in the future.
