摘　　要：针对黄河流域内蒙古段十大孔兑地区地下水超采、“粮能争水”导致的黄河流域局部地区水资源短缺问题,基于“量、质、域、流”多维水资源承载力评价框架,利用层次分析法和熵权法对评价指标进行主、客观组合赋权,应用TOPSIS模型对区域水资源承载力进行多维度综合分析。结果表明:2000—2020年研究区水资源综合承载力呈上升趋势,但整体处于临界可承载状态;水资源维度承载力:量>流>质>域,水资源承载子系统承载力:利用方式>承载体>承载对象。总体来看,国家最严格水资源管理制度“三条红线”的刚性约束以及河(湖)长制的全面推行,倒逼区域水资源“质”和“流”维度承载力提升,但持续高强度的水资源开发利用,使得“量”和“域”维度承载力下降显著;未来需要进一步优化农业与工业用水格局,重点解决“粮能争水”问题,加大对现有河湖水资源引入等措施来实现经济社会的可持续发展与水资源荷载平衡。Ten Kongdui region in the Inner Mongolia section of the Yellow River Basin is facing the shortage of water resources caused by the overexploitation of groundwater and the predicament of“food and energy competing for water”.In view of this problem,the multi-dimensional water resources carrying capacity evaluation framework of“quantity-quality-domain-flow”was constructed,and the evaluation indicators were weighted subjectively and objectively using analytic hierarchy process and entropy weight method.Then the TOPSIS model was used to carry out the multi-dimensional comprehensive analysis of the regional water resources carrying capacity.The results show that the comprehensive carrying capacity of water resources in the study area showed an upward trend from 2000 to 2020,but the overall carrying capacity was in a critical carrying state;water resources dimension carrying capacity is ranked as follows:quantity>flow>quality>domain,and water resources subsystem carrying capacity is ranked as follows:water use pattern>carrier>carrying object.Overall,the rigid constraints of the“three red lines”of the country’s most stringent water resources management system and the full implementation of the river and lake chief system have forced the regional water resources to increase their carrying capacity in the“quality”and“flow”dimensions.However,continued high-intensity water resources development and utilization have significantly reduced the carrying capacity of the“volume”and“domain”dimensions.In the future,it is necessary to further optimize the water use pattern of agriculture and industry,focus on solving the problem of“food and energy competing for water”,and increase the diversion of the existing river and lake water resources to achieve sustainable social and economic development and water resources load balance.
