摘　　要：评价黑河中游水资源承载力对促进该区域水资源的高效利用并推动经济可持续发展具有重要意义。为此,选取10个主要评价指标,并采用模糊综合评判模型定量分析了黑河中游2000~2020年水资源承载力动态变化状况。结果表明,黑河中游水资源承载力综合评分值在0.3~0.5之间,其中最高值出现在2020年,达到0.471,整体水资源承载力处于中级阶段,即可承载状态。黑河中游应调整用水结构,加强发展节水型经济和生态环境保护,以提高水资源的合理高效利用。The evaluation of carrying capacity of water resources in the middle reaches of the Heihe River is important to promote the efficient use of water resources and sustainable economic development of the region. This paper quantitatively analyzed the dynamic changes of the water resources carrying capacity of the middle reaches of the Heihe River from 2000 to 2020 by selecting 10 evaluation indexes and using the fuzzy comprehensive evaluation model. The results show that the water resources carrying capacity of the region is between 0.3 and 0.5, with the highest value reaching 0.471 in 2020, and the water resources carrying capacities are in a bearable state. In order to improve the rational and efficient use of water resources, the middle reaches of the Heihe River should adjust the water use structure and strengthen the development of water-saving economy and ecological environmental protection.
