平原区深层地下水资源可恢复性研究

为合理开发深层地下水资源,确定深层地下水资源的可恢复性,以桓台县为例,在分析其水文地质条件的基础上,依据地下水位动态监测及地下水水质取样分析,通过对水动力和水化学动态特征两个方面的研究,探讨深层地下水资源的构成及特性.研究表明:随着不断超量开采,研究区深层地下水水位下降速率加大,深层地下水接受浅层越流补给和侧向径流补给特征明显,激发越流补给增加,但水化学组分并没有明显改变,深层地下水资源具有一定的可恢复性,但开采量必须得到合理控制.

Recoverability of Deep Groundwater Resource in Plain Areas

Based on the analysis of hydrogeology condition in researched areas and the monitoring data on deep groundwater level and quality,this article studies the recoverability of deep groundwater resources for rational development and utilization by means of analyzing their dynamic characteristics of hydrodynamic and hydrochemistry.Results show that the drawdown rate of water level increases,the feature of leakage recharge and lateral runoff recharge becomes obviously and the excited leakage recharge increases with excessive exploitation,but chemical components of deep groundwater do not change significantly.This study proves that deep groundwater resource has certain recoverability if exploitation quantity is reasonable.
