摘要: 合理的生态管控分区对科学制定重点生态功能区保护和管理策略具有重要意义。以修河流域重点生态功能区为研究区,基于生态风险和生态韧性双视角,综合评估并探讨了二者之间的时空分异特征和空间相关特性,利用四象限法构建了基于二者的生态管控分区方案。结果表明:(1)研究区以低、较低风险和高、较高韧性为主,生态风险和生态韧性分别呈现出以修河干流为主线的“南北低、东高西中”和“南北低、东西高”的态势,且都呈上升的趋势;(2)三期生态风险与生态韧性的莫兰指数分别为-0.597、-0.616和-0.663,二者存在显著的空间负相关性且负相关性在逐渐增强;(3)研究区共划分为四个生态管控分区,其中以低风险-高韧性区为主,占整个研究区的60%以上,呈增加的趋势,其余分区呈减少的趋势。基于“风险-韧性”的生态管控分区具有一定的科学性和可操作性,可为修河流域重点生态功能区制定出具有针对性、差异化的保护和管理策略。

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.
