Abstract: Effective ecological management and control zoning is crucial for the scientific formulation of protection and management strategies in key ecological function areas. Using the key ecological function areas of the Xiuhe River Basin as a study area, the spatial-temporal differentiation and spatial correlation characteristics of ecological risk and ecological resilience were comprehensively evaluated and analyzed in this paper. Furthermore, an ecological management and control zoning scheme was developed based on the four-quadrant method. The results indicated that: (1) The study area was primarily characterized by low ecological risk and high ecological resilience. Both ecological risk and resilience displayed a spatial pattern of "low in the north and south, high in the east and central west" for risk, and "low in the north and south, high in the east and west" for resilience, with the main stream of the Xiuhe River serving as the primary axis. Both factors exhibited an increasing trend. (2) The Moran index of ecological risk and resilience in the third phase was -0.597, -0.616 and -0.663, respectively, indicating a significant negative spatial correlation between the two, which increased progressively over time. (3) The study area was divided into four ecological management and control zones, among which the low-risk-high-resilience zone was the main area, accounted for more than 60% of the entire study area, which exhibited an increasing trend, and the rest of the zones exhibited a decreasing trend. The ecological management and control zoning based on the "risk-resilience" approach exhibits scientific validity and operational feasibility, allowing for the development of targeted and differentiated protection and management strategies for key ecological function areas in the Xiuhe River Basin.
