【摘要】：南水北调受水区是我国水资源最为短缺的地区之一。按照实行最严格水资源管理制度的要求,面向"节水优先"的国家水安全保障战略,开展受水区节水分析。基于对现有节水评价指标分析的基础上,构建了能够全面反映区域用水结构和全社会全过程用水效率的评价指标与评价标准。采用单一指标评价法,系统剖析受水区通水前后(2003-2015年)综合节水情势和各行业节水变化趋势,并利用所构建的综合评价体系对2015年受水区县、市用水效率进行综合评价。评价结果显示近年来,受水区大力节水,用水效率大幅度提高,但与国际先进节水水平相比较,受水区节水工作还存在很多改进空间,节约用水仍有一定潜力。
[Abstract]:The south-to-north water transfer area is one of the areas with the most shortage of water resources in China. According to the requirement of implementing the strictest water resources management system and facing the national water security strategy of "water saving first", the water saving analysis in the receiving area is carried out. Based on the analysis of the existing water-saving evaluation indexes, an evaluation index and evaluation standard which can reflect the regional water use structure and the whole process water use efficiency of the whole society are constructed. A single index evaluation method was used to systematically analyze the comprehensive water saving situation before and after water opening (2003-2015) and the changing trend of water saving in various industries. The comprehensive evaluation system was used to evaluate the water use efficiency of counties and cities in 2015. The evaluation results show that in recent years, the water-saving area has greatly improved the efficiency of water use, but compared with the international advanced water-saving level, there is still a lot of room for improvement of water-saving work in the water-receiving area, and there is still some potential for saving water.
