大中型灌区水权转让节水工程节水效果评估方法研究OA

China's water resources face issues like uneven spatial and temporal distribution,tightening rigid constraints,and prominent supply-demand conflicts.Implementing water rights allocation and trading is an important way to optimize water resource distribution.To meet the needs of water rights transfers,this study proposed a method to assess the water-saving effects of water-rights transfer projects in medium and large irrigation areas.Taking a large irrigation area in the Yellow River Basin as an example,the study used water conveyance efficiency analysis and water balance methods to evaluate the project's water-saving capacity and actual water saved,and analyze the effects of water-saving renovation projects in the area.The results show that:The water-saving capacity of the lined canal sections is 92.19 million m3,with a water-saving goal closeness of 0.96.The actual water saved by the project in 2025 is 95.52 million m3,and considering above-average rainfall in 2025,the normal water saved would be 92.18 million m3.Carrying out engineering water-saving effect evaluation based on measured data yields results that better reflect the actual operation conditions of irrigation areas.
