摘　　要：[目的]揭示水土资源适宜性多体系综合评价对区域发展的贡献,阐明宁夏地区水土资源协调发展的适宜性演变情况,识别区域水土资源承载能力的影响因子。[方法]通过构建宁夏资源-生态-社会-经济综合评价体系,基于熵权TOPSIS模型、耦合协调度模型及灰色关联度模型,评价了宁夏近20年(2001—2020年)水土资源适宜性动态变化和协调发展水平,并分析影响因子的变化规律。[结果]宁夏水土资源适宜性呈现出从较差持续向好的发展态势,目前为优质水平(0.883);子体系之间的耦合协调程度由2001年的严重失调(0.159)上升至2020年的优质协调(0.946);各子体系中对水土资源适宜性评价的关联度较高的是资源评价体系(0.729)和社会评价体系(0.721)。[结论]子体系之间的协调发展反映出宁夏水土资源适宜性整体呈现向好态势,未来需要更多关注资源和社会体系中的关键因子,合理配置水土资源的开发利用。[Objective]This study reveals the contribution of multi-system comprehensive evaluation of water and soil suitability of water and soil resources to regional development,clarifies the suitability evolution of coordinated development of water and soil resources in Ningxia,and identifies the influence factors of regional carrying capacity of water and soil resources.[Methods]A comprehensive evaluation system of resources,ecology,and social economy in Ningxia was built up.An entropy weight TOPSIS model,a coupling coordination degree model and a gray correlation degree model were used to evaluate the dynamic changes and coordinated development of water and soil resources in Ningxia in the past 20 years(2001—2020)and analyze the change rules of influencing factors.[Results]The suitability of water and soil resources in Ningxia had a trend from poor to good level and is currently at a high-quality level(0.883).The degrees of coupling and coordination between the sub-systems had increased from a serious imbalance(0.159)in 2001 to a high-quality coordination(0.946)in 2020.The resource evaluation system(0.729)had a higher correlation in the evaluation of the suitability of water and soil resources among the sub-systems and social evaluation system(0.721).[Conclusion]The coordinated development of sub-systems reflects the overall suitability of soil and water resources in Ningxia.In the future,more attention should be paid to the key factors in the social system,and the development and utilization of soil and water resources should be rationally allocated.
