摘要
为了分析彰武县2019年高效节水灌溉项目可行性,项目区设计水平年多年平均地下水资源可利用量为741.08万m3,设计水平年总需水量为375.63万m3,地下水资源量大于总需水量.项目实施过程中无需从外界客土,开挖土方就地回填,回清淤土方就近堆放沟边或就近填坑处理,不向项目区外运输,经分析评价项目可实现水土资源平衡.
Abstract
n order to analyze the feasibility of high-efficiency water-saving irrigation project in Zhangwu County in 2019,the average annual availability of groundwater resources in the project area is 7,410,800 m3 at the design level,and the total annual water demand at the design level is 3,756,300 m3,with the groundwater resources greater than the total water demand.During the implementation of the project,it is not necessary to excavate the external passenger soil,backfill it on the spot,return the dredged soil to the nearby ditch or fill the nearby pit for treatment,and do not transport it outside the project area.Through analysis and evaluation,the project can achieve the balance of water and soil resources.
