Abstract

Water resources are an important influence factor of land remediation. As support of food production, analysis of soil and water resources supply and demand balance is an important part and technical support of the construction. According to some relevant calculation formulas on water resources assessment, after forecast of water demand and the calculation of water supply, in the project area of the demonstration construction of whole rural land remediation in Fuyu County, the average water availability for many years is 70581.6 thousand m3 each year, including surface water availability 57003.3 thousand m3 and groundwater availability 13578.3 thousand m3. Water demand is 58806.2 thousand m3 in 2015; including water demand for life 5150.9 thousand m3 and water demand for agricultural irrigation 53655.3 thousand m3. Water supply is more than water demand; the basic supply-demand balance can be achieved in conditions of the design of water supply project.
