摘要:

【目的】评价引江济淮工程河南受水区现状节水水平。【方法】从综合、农业、工业、生活、生态环境5个方面选取11项用水指标建立引江济淮工程河南受水区节水水平评价指标体系，构建基于AHP-CRITIC法组合权重的TOPSIS模型，对受水区2020年节水水平进行综合评价。【结果】受水区9个县区中，评价分级为Ⅰ级的有1个（永城市），Ⅱ级5个（梁园区、鹿邑县、睢阳区、柘城县、夏邑县），Ⅲ级3个（郸城县、淮阳区、太康县）。节水水平Ⅱ级（较高）以上的县区占比为66.7%，受水区整体节水水平较高。万元GDP用水量、节水灌溉率、城镇人均生活用水量、城镇公共供水管网漏损率、再生水利用率是制约受水区节水水平的主要影响因素。评价结果与受水区实际情况基本相符。【结论】基于AHP-CRITIC组合赋权的TOPSIS评价方法适用于评价引江济淮工程河南受水区现状节水水平，评价结果与区域实际情况相符，可为水资源优化调配提供参考。

Abstract:

【Objective】The Yangtze-to-Huaihe hydraulic project was initiated in 2016 to move water from the Yangtze River to the Huai River to alleviate water shortage in the latter. In this paper, we analyze water saving levels in the beneficiary areas located in Henan province.【Method】We selected 11 water-related indexes covering agriculture, industry, living and ecological environment in the comprehensive analysis to establish an index system to evaluate water-saving levels in the beneficiary areas. A TOPSIS model was then derived, based on the combined weight of AHP-CRITIC method to evaluate water-saving levels in 2020.【Result】Among the nine counties we studied in the analysis, one county (Yongcheng) reached grade I, five counties (Liangyuan, Luyi, Suiyang, Zhecheng and Xiayi) reached grade II, and three counties (Dancheng, Huaiyang, Taikang) reached grade III water saving levels. Overall, water-saving levels in the beneficiary areas were higher. Water consumption per 10000-yuan GDP, water-saving irrigation rate, domestic water consumption per capita in urban areas, leakage losses from the water supply network in urban areas, and reclaimed water utilization were the factors that influenced the water-saving levels in the beneficiary areas. The evaluated results were consistent with the ground-truth data observed in the studied areas.【Conclusion】The TOPSIS method based on the AHP-CRITIC combination weighting is reliable for evaluating water-saving levels at regional scale. Our results provide guidelines for optimal allocation of the diverted water to the beneficiary areas in Henan province.
