基于单位脉冲-海水入侵响应矩阵的地下水管理模型及应用

Research on groundwater management model and its application based on unit pulse saline intrusion response matrix

分析了目前我国地下水管理模型研究的现状,针对我国沿海城市普遍存在的海水入侵问题,提出了建立单位脉冲-海水入侵响应函数的思路和方法,并以此为基础构筑大连市地下水系统管理模型,针对现状开采井布局制定两个优化管理方案:一个是在满足各约束条件下获取最大开采量;另一个是保持天然径流的10%排泄入海时,求取最优开采量.该研究成果可为解决我国沿海城市地下水资源开发与海水入侵的矛盾提供参考.

By summarizing the current research in the field of groundwater management, the saline intrusion in the coastal zones was analyzed. The way forming pulse-saline intrusion coefficients is discussed. Then a groundwater management model for Dalian was developed based on the coefficients and two optimal schemes were provided. Both schemes are based on current wells distribution. One is to maximize groundwater pumping quantity under related constrains. The other is the same except keeping 10% natural groundwater disputing to sea. The results may be used for the groundwater management in other coastal zones.
