摘　　要：针对我国大都市边缘区国土空间生态修复关键区域识别的实际需求问题,以武汉市新洲区为例,综合形态学空间格局分析、最小累积阻力模型、生态退化评估等方法,耦合人类干扰构建生态网络,结合生态退化状况识别修复关键区并提出分类修复策略。研究结果表明:研究区共有生态源地31块,占区域总面积14.1%;潜在生态廊道北疏南密,共65条,平均长度4.6 km;生态障碍点共50个;研究区修复关键区共10.25 km^(2);将修复关键区分为河湖退化、山体破坏、城镇空间和道路阻隔4类实施针对性修复策略。修复关键区空间分布既与生态安全网络分布格局相关,也受大都市发展方向的影响。本研究可为新时代大都市边缘区国土空间生态修复提供科学参考与决策依据。Aiming at the actual demand problem of identifying key areas for ecological restoration of national land space in the fringe area of metropolis in China, this study takes Xinzhou District of Wuhan as an example, synthesizes the methods of morphology spatial pattern analysis, the least cumulative resistance model, and ecological degradation assessment, and constructs an ecological network by coupling human interference, and identifies the key areas for restoration in conjunction with ecological degradation conditions and puts forward the categorized restoration strategy. The results of the study show that: there are 31 ecological source areas in the study area, accounting for 14.1% of the total area of the area;potential ecological corridors are sparse in the north and dense in the south, with a total of 65 corridors, with an average length of 4.6 km;and there are 50 ecological obstacles;the restoration key areas in the study area are a total of 10.25 km^(2);the restoration key areas can be divided into four categories: degradation of rivers and lakes, destruction of mountains, urban space, and road obstruction to implement targeted restoration strategies. The spatial distribution of restoration critical areas is not only related to the distribution pattern of ecological safety network, but also influenced by the direction of metropolitan development. This study can provide scientific references and decision-making basis for the ecological restoration of land space in the fringe areas of metropolis in the new era.
