| 探究生态风险与生态韧性的演变与耦合关系对于改善沿河生态脆弱性具有重要意义。以霍邱县为例，运用景观生态风险指数模型和生态韧性模型分析 2002—2022年生态风险与生态韧性时空演化特征，并运用四象限法、耦合协调度模型完成霍邱县“韧性—风险”生态分区和耦合协调分区。结果表明：（1）2002—2022年，霍邱县生态风险水平整体呈下降趋势，生态韧性水平呈现先下降后上升的趋势。（2）在空间分布方面，霍邱县生态风险以水域为中心向四周扩散；生态韧性呈现“中东部高，四周低”的空间格局，高韧性区集中在以水域和林地为主的高植被覆盖区域。（3）生态分区以“低韧性－低风险”“高韧性－高风险”为主，耦合协调分区以中度失调和中度协调为主，较高耦合协调区主要分布于以城西湖、城东湖为中心的水域。 |

| It is of significance to explore the evolution and coupling relationship between ecological risk and ecological resilience to improve the riverside ecological vulnerability. Taking Huoqiu county as an example, this paper analyzes the spatiotemporal evolution characteristics of ecological risk and ecological resilience from 2002 to 2022 by using the landscape ecological risk index model and ecological resilience model, and the resilience-risk ecological zoning in Huoqiu county are completed by using the four-quadrant method and coupling coordination degree model. The results show that from 2002 to 2022, the level of ecological risk in Huoqiu county shows an overall decreasing trend, and the level of ecological resilience a decreasing-increasing trend. In terms of spatial distribution, the ecological risk in Huoqiu county centred on watersheds and spread out; the ecological resilience is high in the east-central pattern and low around it, with the high resilience areas concentrated in areas with high vegetation cover such as watersheds and forested land. The ecological zoning types are dominated by low resilience-low risk and high resilience-high risk, and the coupling coordination zoning is dominated by moderate dissonance and moderate coordination. The higher coupling coordination zone is mainly distributed in the waters centred on the Chengxi lake and Chengdong lake. |
