Analysis on Irrigation Utilization Scheme of Dali River in Zizhou County
Water resources are in short supply in the loess plateau region.In order to improve the utilization of water resources and make up for the problem of agricultural irrigation water demand,based on the status quo of sewage treatment,river water quality and irrigation utilization in the Dali river basin,the method of water supply and demand balance was adopted to discuss the utilization scheme of irrigation water based on the analysis of irrigation demand and availability.This paper puts forward the scheme of using rolling dam to hold water,pump water to the treatment plant,and then the treated water enters the reservoir through the lifting pump station for ecological node and ecological forest(carbon sink forest)irrigation,which can provide scientific basis for sewage treatment and agricultural irrigation of the Dali river basin.
