基于MSPA的区域绿色基础设施构建——以苏锡常地区为例

Construction of Regional Green Infrastructure Based on MSPA—Case Study on Suzhou-Wuxi-Changzhou Area

摘要: 区域绿色基础设施普遍被视为维护区域生态安全的有效途径，其构建方法对于其功能实现具有重要作用。形态学空间格局分析（MSPA）方法，具有需求数据量小、分析与规划匹配度高等优势，成为近年研究与应用的热点。在分析MSPA应用原理的基础上，整合遥感、GIS技术，通过绿色基础设施要素提取、景观连接度评价、最小路径分析对生态廊道进行分级，并以长三角苏锡常地区为例，验证技术框架的可行性，得到苏锡常区域绿色基础设施规划空间结构，并对网络结构提出优化策略。

Abstract: Regional green infrastructure is widely regarded as an effective way to maintain the regional ecological security. Its construction approaches are important to its function implementation. MSPA (Morphological Spatial Pattern Analysis), as a new method, with advantages of better fitness for analysis and planning and fewer data demand, becomes a hotspot for regional green infrastructure construction. This research built a framework of regional green infrastructure by MSPA under its theoretical basis, including extracting green infrastructure elements, evaluating landscape connection degree of green infrastructure elements and formatting the classified network combined with ENVI, GIS. Finally MSPA was used to construct green infrastructure in Suzhou-Wuxi-Changzhou area.
