摘要(Abstract)：

【目的】研究区域水资源承载力是发现和解决区域水资源问题的重要途径。【方法】基于“驱动力-压力-状态-影响-响应”的DPSIR模型，构建安徽省水资源承载力评价指标体系，利用熵权法与变异系数法组合赋权，使用TOPSIS、标准差椭圆、空间自相关法和地理探测器，测算并分析2011—2020年安徽省水资源承载力时空分异特征，探究造成水资源承载力时空异质性的驱动因子。【结果】(1)研究期内，安徽省水资源承载力水平由0.279增加到0.703,等级Ⅳ区域由0个增加到11个，等级Ⅰ区域由8个减少到0个。(2)安徽省水资源承载力空间上呈现“南-中-北”阶梯式递减分布格局，其北部地区水资源承载力增速相对较强，且各地级市水资源承载力的空间聚集性不断弱化。(3)各驱动因子在不同时期对水资源承载力的时空分布影响程度有显著差异，主导驱动因子趋于多元化，但自然禀赋始终是核心因子。任意因子交互作用后，均表现为双因子增强(68.57%)或非线性增强(31.43%)。【结论】整体来看，安徽省水资源承载力水平逐渐提高，为进一步提高水资源承载力，各城市需因地制宜制定发展规划，重点关注影响水资源承载力的主导因子。
