Analysis on Water Resources Supply and Demand Balance of Major Engineering Project of Rural Land Remediation in Jilin Province

Abstract

Water resources are an important influence factor of land remediation in Jilin Province. As support of food production, analysis of water resources supply and demand balance is an important part and technical support of the construction. After forecast of water demand and the calculation of water supply, in major projects areas of the demonstration construction of whole rural land remediation in Jilin province, the average water availability for many years is 736796.1 thousand m3 each year, including surface water availability 543393 thousand m3 and groundwater availability 193403.1 thousand m3.water demand is 463 694.4 thousand m3 in 2015; including water demand for life 49150 thousand m3 and water demand for agricultural irrigation 414544.4 thousand m3. 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 every project area.
