Research and Application of Small-scale Typical Rural Water Resources Balance Model
The problems of water resources and water environment in rural areas are widely concerned.Based on the law of dualistic water cycle,this paper systematically analyzes the change laws of different types of water in rural areas from natural and social,and constructs the rural water balance model and rural water quantity calculation model.The wa-ter balance model summarizes the change law of water resources in rural areas,and the water calculation model is used to construct the calculation methods of different types of water.The amount of water resources in a typical village in Central Shanxi was calculated by using the meteorological,soil and survey data to verify the scientificity of the water balance model.The error of water resources balance model is 3.12%,which can better reflect the relationship between the input and output of rural water resources,and the proportion of water input and output under natural force is 60.72%and 95.27%respectively,which has a stronger"natural"attribute.It can provide theoretical support for improving the effi-ciency of water resources utilization in rural areas,optimizing the allocation of rural water resources,and solving systemic water resources problems.
