摘　　要：以武汉城市圈为研究对象识别国土空间生态修复区,运用MSPA方法、景观连通性评估、MCR模型和电路理论构建以“生态源地-生态廊道-生态节点”组成的生态安全格局,基于VSD模型评价研究区2010年和2018年的生态脆弱性,综合两者识别出的生态修复区分类提出针对性修复保护措施。研究结果:①共识别出10处生态源地,总面积14 761.9 km^(2),45条生态廊道,19处生态“夹点”,7处生态障碍点。② 2010—2018年研究区生态脆弱度分别以潜在脆弱和轻度脆弱为主,潜在脆弱区面积占比下降12.85%,轻度脆弱区增加4.49%,非常脆弱区与极度脆弱区占比较小,合计占比从12.44%增长至16.89%。③共识别4处生态修复区,总面积3 779.7 km^(2),分为生态景观重塑区、重要廊道贯通区、人工修复区、产业转型区。本文将生态脆弱性评价结果融合到生态安全格局中能够更全面地识别国土空间生态修复区,共同保障城市圈区域经济与生态环境的协调发展。The identification of ecological restoration areas in territorial space is a crucial aspect of the ongoing project for ecological protection and restoration,in order to implement the ideology of ecological civilization in the new era.Currently,research on ecological restoration areas in territorial space is mostly based on the identification of ecological security patterns,without sufficient consideration of regional characteristics.This paper incorporates ecological vulnerability assessment to improve the methodological framework for identifying ecological restoration areas in territorial space.Using the Wuhan metropolitan area as a case study,it explores new pathways for enhancing ecological environment protection in mega-city regions.The MSPA,MCR model,and circuit theory were employed to construct an ecological security pattern consisting of“ecological source-ecological corridor-ecological node”.Based on the VSD model,a comprehensive evaluation index system was established,with 16 influencing factors derived from nine levels including human activities,socioeconomic factors,and natural conditions,focusing on exposure,sensitivity,and adaptive capacity.The ecological vulnerability of the study area in 2010 and 2018 was assessed.Finally,the ecological restoration areas were identified by integrating the results and targeted restoration and protection measures were proposed.1)A total of 10 ecological source areas were identified,covering a total area of 14761.9 km^(2).They were mainly distributed in the Yangtze River Basin,northeastern Huanggang City,and southeastern Huangshi City.There were 45 ecological corridors,including 17 important corridors and 28 general corridors.There were 19 ecological pinch-points and 7 ecological barriers,mainly concentrated in the northern,central,and southern parts of the Wuhan metropolitan area.2)The ecological vulnerability of the study area showed potential fragility and mild fragility in both 2010 and 2018.The proportion of potential fragile areas decreased by 12.85%,while mi
