河南省“十三五”时期节水效果评估

Evaluation of Water Saving Effect in Henan Province during the 13th Five-Year Plan Period

摘要: 河南省水资源紧缺，供需矛盾突出。本文在分析河南省用水量变化的基础上，对2020年全省节水量、用水效率与用水水平进行了评估，主要结论为：“十三五”期末，全省年节水量约18.8亿m3，其中工业节水量最大，农业节水量较小；“十三五”时期全省用水效率持续提升，用水指标优于全国平均水平；但劣于华北地区用水指标，用水效率有提升空间。通过节水效果评估，简要提出了今后提高用水效率的应对措施。

Abstract: Henan Province is short of water resources and the contradiction between supply and demand is promi-nent. Based on the analysis of the change of water consumption in Henan Province, this paper analyzes and evaluates the Henan water saving, water efficiency and water use level in 2020. The main conclusions are as follows: at the end of the 13th Five-Year plan, the annual water saving of the whole province is about 1.88 billion m3, of which the industrial water saving was the largest and the agricultural water saving was less; During the 13th-Five Year Plan period, the water use efficiency of the province continued to improve, and the water use index was better than the national average level. Compared with North China, the water use level of Henan Province was still low and has room for improvement. Through the evaluation of wa-ter-saving effect, this paper briefly presents some countermeasures in the future.
