摘　　要：毛乌素沙地是我国现存的最具代表性的沙地治理典型示范区,优化水资源开发利用格局,同时满足日益增长的生活水平和维护生态治理成果的要求,对于全面迈进高质量发展道路具有重大意义。以内蒙古鄂尔多斯毛乌素沙地地区为研究对象,开展基于WEAP-MODFLOW耦合模型的毛乌素沙地水资源优化配置以及配置后承载力评价,结果表明:当前政策供水能力下,规划期内研究区无法满足水资源供需平衡等要求,且综合预案较预测承载力提升作用较小,而充分挖潜供水能力后的预案则有较大提升;最优配置预案为T14,其承载力达到3.80,接近“优质承载”等级,该预案配置为:至2030年,灌溉水利用系数达到先进值0.8,实现工业需水量不超过12065万m³,每年适度增加3%的生态需水量,同时充分挖潜研究区地下水与疏干水的利用潜力,使地下水、疏干水可供水量达到43279、24744万m³且地表水可供水量保持3138万m³不变。Protecting water resources and the ecological environment is crucial for Yellow River governance and basin economic development.The Mu Us Sandy Land,a prime example of sand control in China,plays a pivotal role.Against the backdrop of economic reform and ecological civilization,optimizing water resource development and usage to meet rising living standards while preserving ecological gains is vital for high-quality development.Research on water resource optimization and carrying capacity in the Mu Us Sandy Land reveals that current policies fall short of balancing supply and demand,but tapping into water supply potential significantly improves outcomes.The optimal allocation plan is T14,with a carrying capacity of 3.80,approaching the"high-quality carrying"level.This plan includes achieving an advanced irrigation water use coefficient of 0.8 by 2030,ensuring that industrial water demand does not exceed 120.65 million cubic meters,moderately increasing the ecological water demand by 3%annually,and fully tapping the potential of underground water and drainage water utilization in the research area.This results in groundwater and drainage water availability reaching 432.79 million cubic meters and 247.44 million cubic meters respectively,while surface water availability remains unchanged at 31.38 million cubic meters annually.
