吉林省松嫩平原地下水超采形势分析

通过对松嫩平原地下水超采形势分析,掌握地下水资源的补给及开发利用状况、地下水位下降趋势情况,为监测、监督地下水的过量开采与污染、保护、合理利用地下水资源,促进地下水可持续利用提供基础数据与决策依据。依据近10年地下水水位、水质监测数据,采用超采系数法、地下水位下降速率法,结合地下水资源均衡和地下水水质污染情况,通过数值模拟、数理统计、条件类比、地质分析等方法,综合分析确定地下水超采形势。

Situation analysis about groundwater overdraft in Songnen plain of Jilin Province

The situation of the groundwater recharge, exploitation development and utilization and groundwater lowering trend are known based on the groundwater overdraft situation analysis of Songnen plain, it provides basic data and basis for decision-making to monitor and supervise the groundwater overdraft, pollution, protection, and rational use of groundwater resources and promote the sustainable use of underground water. The situation of groundwater overdraft is determined according to the water quality monitoring data and groundwater level for 10 years, the calculating overdraft coefficient, declining rate of the underground water level, and the balance of groundwater resources and groundwater pollution situation, through the numerical simulation, mathematical statistics, comparison, analysis, the other methods of geological conditions and the comprehensive analysis.
