摘要: 本文基于2009、2012、2015、2018、2021年统计、国土调查和影像数据,采用熵权法和TOPSIS模型协同分析黄河流域(甘肃段)57个县级行政区的水资源承载力水平。结果表明:①2009—2021年,黄河流域(甘肃段)水资源子系统、社会经济子系统和生态环境子系统等级低和较低的县级行政区数量明显减少,等级高和较高的数量增加;②黄河流域(甘肃段)水资源承载力为不理想的区域集中位于陇中及陇东,水资源承载力为中等理想、较理想和理想的区域集中在玛曲、碌曲、卓尼及夏河县等甘南高原区域;③研究时期内,黄河流域(甘肃段)大部分区域水资源承载力为稳定或提高,这也反映了近20年环境治理成效显著,水源涵养能力与水资源综合利用效率稳步提升。

Abstract: Based on the statistical, territorial survey and image data of 2009,2012,2015,2018 and 2021, the entropy weight method and TOPSIS model are used to collaborative analysis the water resources carrying capacity of 57 county-level administrative regions in the Yellow River basin(Gansu section). The results show that: ①From 2009 to 2021, the number of county-level administrative districts with low levels of water resources subsystem, socio-economic subsystem and ecological environment subsystem in the Yellow River basin (Gansu section) decreased significantly, while the number of high levels increased. ②The regions of the Yellow River basin (Gansu section) with unsatisfactory water resources carrying capacity are concentrated in Longzhong and Longdong, while the regions of Maqu, Luqu, Zhuoni and Xiahe county with medium ideal, relatively ideal and ideal water resources carrying capacity are concentrated in Gannan plateau. ③During the study period, the water resources carrying capacity in most regions of the Yellow River basin (Gansu section) is stable or increased. This also reflects the remarkable results of environmental governance in the past two decades, and the steady improvement of water conservation capacity and comprehensive utilization efficiency of water resources.

Key words: water resources carrying capacity, index system, entropy weight method, TOPSIS model, the Yellow River basin(Gansu section)
