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.
