摘要
根据黄河流域生态环境质量提升和高质量发展的国家战略要求,为推动水资源节约集约利用,构建涉及水资源系统、社会经济系统、生态环境系统的15个指标评价指标体系,采用熵权法,对2018-2021年黄河流域上中游50个地级市水资源节约集约利用水平进行评价,并利用障碍度模型识别影响水资源节约集约利用水平的主要因素。结果表明:研究区水资源节约集约利用水平整体呈上升趋势,由2018年的0.505增长到2021年的0.553;再生水利用率、农业用水比例和污水处理率是影响研究区水资源节约集约利用水平提升的主要障碍因子。在此基础上,从水资源节约集约利用措施和非常规水资源利用措施2个方面提出了水资源节约集约利用的建议。
Facing the national strategic requirements of improving the ecological environment quality and high⁃quality development in the Yellow River Basin,in order to promote the conservation and intensive utilization of water resources,this paper constructed 15 evaluation in⁃dexes including water resources system,socio⁃economic system and ecological environment system.The entropy weight method was used to evaluate the water resources conservation and intensive utilization level of 50 cities in the upper and middle reaches of the Yellow River Basin from 2018 to 2021,and identified the main factors affecting the water resources conservation and intensive utilization level of cities in the study area by using obstacle model.The results show that the overall level of conservation and intensive utilization of water resources in the study area is on the rise,from 0.505 in 2018 to 0.553 in 2021.The utilization rate of reclaimed water,the proportion of agricultural water use and the sewage treatment rate are the main obstacle factors affecting the improvement of the level of conservation and intensive utilization of water resources in the study area.Based on this analysis,the countermeasures for the conservation and intensive utilization of water resources were put forward from four aspects of water saving,social and economic development,ecological environment protection and unconventional water resources utilization.
