摘　　要：国土空间生态修复是落实生态文明建设的重要举措,精准识别生态修复区域以及合理划定修复的优先序,是科学有序推进国土空间生态修复的前提,因此,本文以黄河流域山东段为研究区,通过“生态韧性-人类干扰”定量评估生态系统退化风险,采用形态学空间格局分析(MSPA)、景观连通性评价和电路理论模型等方法构建生态安全格局,识别生态源地、廊道、夹点、障碍点等生态要素作为生态修复区域,叠加退化风险等级对修复区域进行优先序划定,并提出相应修复策略.结果表明:研究区总体生态退化风险较高,高退化风险区以各城市为中心呈带状辐射分布,快速城镇化以及交通网络的发展对生态退化的影响不容忽视;识别生态修复区域,包括27个生态源地、71条生态廊道、71处生态夹点和51处生态障碍点;叠加生态退化风险,将生态修复区域划分为优先修复、一般修复以及生态保育三类,并结合不同生态要素特征以及优先序提出修复策略.Ecological restoration of territorial space is a critical measure for advancing the construction of ecological civilization.Precise identification of areas requiring ecological restoration and rational delineation of restoration priorities are fundamental prerequisites for the scientific and orderly promotion of territorial ecological restoration.This paper selected the Shandong Section of the Yellow River Basin as the research area and quantitatively evaluated the risk of ecosystem degradation using the"ecological resilience and human disturbance"framework.An ecological security pattern was constructed through Morphological Spatial Pattern Analysis(MSPA),landscape connectivity assessment,and circuit theory models,identifying key ecological factors such as source areas,corridors,pinch points,and barrier points.By overlaying these factors with ecological degradation risks,the priority levels of restoration areas were determined,and corresponding restoration strategies were formulated.The results indicated that the overall risk of ecological degradation in the study area was high,with high-risk areas exhibiting a zonal radiation distribution centered around each city.The influence of rapid urbanization and the expansion of transportation networks on ecological degradation cannot be overlooked.A total of 27 ecological sources,71 ecological corridors,71 ecological pinch points,and 51 ecological barrier points were identified as ecological restoration areas.Overlapping ecological degradation risks,ecological restoration areas were divided into priority restoration,general restoration and ecological conservation,and restoration strategies were proposed in conjunction with the characteristics of different ecological elements and their priority order.
