摘要

Water resources are an important influence factor of land remediation. As support of food production, analysis of 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 Baishan City, the average water availability for many years is 8990.1 thousand m~3 each year, in which surface water availability is 7210.6 thousand m~3, groundwater availability is 1579.4 thousand m~3. Water demand is 5552.4 thousand m~3 in 2015, in which water demand for life 4165.2 thousand m~3; water demand for agricultural irrigation is 1387.2 thousand m~3. Water supply is more than water demand; the results show that there is a slight surplus of water resources in the region. The basic supply-demand balance can be achieved in conditions of the design of water supply project in the project area.
