为评估黄河流域九省(区)的水资源可持续利用水平,改善水资源状况,实现地区水资源可持续利用,基于水足迹模型提出适合黄河流域九省(区)的水资源可持续利用综合评价指标,并且使用Spearman相关分析法和多元线性回归分析法对黄河流域九省(区)水资源可持续利用水平的驱动因素进行了分析.研究结果表明:2010-2020 年黄河流域九省(区)的水资源足迹呈现先增后减的小幅度变化,水环境足迹呈现减小的趋势,水资源足迹和水环境足迹空间分布极不均匀;黄河流域九省(区)整体的水资源可持续利用水平出现了不同程度的上升趋势,上游省(区)的水资源可持续利用水平较高,而中下游省份的水资源可持续利用水平较低.水资源可持续利用水平的主要驱动因素为人口密度和第二产业占比,其次为人均用水量、废水处理率和化肥施用强度.
Comprehensive Evaluation of Sustainable Water Resources Utilization in Nine Provinces of the Yellow River Basin Based on Water Footprint
In order to evaluate the sustainable utilization level of water resources in the nine provinces(autonomous regions)of the Yellow River Basin,improve the status of water resources and realize the sustainable utilization of regional water resources,this paper proposed a comprehensive evaluation index of sustainable utilization of water resources suitable for the nine provinces(autonomous regions)of the Yellow River Basin based on the water footprint model.Spearman correlation analysis and multiple linear regression analysis were used to ana-lyze the driving factors of sustainable water resources utilization in the nine provinces of the Yellow River Basin.The results show that the wa-ter resources footprint of the nine provinces(autonomous regions)in the Yellow River Basin from 2010 to 2020 increases first and then de-creases in a small amplitude,and the water environment footprint shows a decreasing trend,and the spatial distribution of water resources footprint and water environment footprint is very uneven.In the nine provinces(autonomous regions)of the Yellow River Basin,the level of sustainable utilization of water resources has increased to different degrees.The level of sustainable utilization of water resources in the up-stream provinces(autonomous regions)is higher,while the level of sustainable utilization in the middle and downstream provinces(autono-mous regions)is lower.The main driving factors of sustainable water resources use are population density,wastewater treatment rate and the proportion of secondary industry,followed by per capita water consumption and fertilizer application intensity.
