摘要为了在生态文明建设背景下,从生态系统完整性和结构连通性角度识别生态修复关键区域,以吉林省松原市为研究区,综合运用MSPA分析､景观连通性评价和电路理论,构建生态安全格局,识别松原市国土空间生态修复关键区域.结果表明:松原市共识别生态源地9处,面积为787.95km²,以水域及草地为主,对区域生态安全起着至关重要的作用;识别生态廊道23条,一级廊道16条,二级廊道7条,全长1458.18km;基于生态安全格局识别松原市国土空间生态修复关键区域,包括生态夹点16处,面积180.70km²,生态障碍点24处,面积298.11km².综合分析生态修复关键区域空间分布和土地利用现状,并提出针对性生态修复策略.

Abstract：From the perspective of ecosystem integrity and structural connectivity in the context of ecological civilization construction, this paper takes Songyuan City, Jilin Province, as the study area. This paper integrated MSPA analysis, landscape connectivity evaluation, and circuit theory to construct an ecological security pattern and identify key areas for ecological restoration in Songyuan City. The results showed that:In Songyuan, a total of 9 ecological sources covering an area of 787.95km² have been identified, with water and grassland being the main components, that plays an important role in regional ecological security. A total of 23 ecological corridors are identified in Songyuan, including 16 primary corridors and 7secondary corridors, with a total length of 1458.18km. Based on the ecological security pattern, the key areas of ecological restoration in Songyuan City are identified, including 16 ecological pinch points with an area of 180.70km² and 24 ecological barrier points with an area of 298.11km². Based on a comprehensive analysis of the spatial distribution and land use status of key ecological restoration areas, targeted ecological restoration strategies are proposed.

Key words： ecological security pattern ecological restoration for territorial space MSPA circuit theory Songyuan City
