Forecast of Water Environment after the Implementation ofWater-Saving Projects

摘要

Inner Mongolia Hetao pla in is the biggest irrigation districts in Northwest China.Because of water shortage in recent years, particularly in Northwest China., so water-savingprojects will be carried out in Hetao irrigation area. This paper aims at reconstruction ofwater-saving projects of Hetao irrigation area in the Yellow River watershed. Through case studyon the Hetao’s Long Sheng irrigation experimental zone ,the groundwater level movement afterwater-saving projects reconstruction is predicted with Galerkin limited elements method .And the predicted results were compared with near Shahaoqu irrigation area. Then the resultswere proved reasonable. So, this results can provide reference for the water environmentalevaluation and management decision of Hetao irrigation area.
