本文阐述了限量开采的定义及确定可开采量的理论基础，并结合永济市城区漏斗区地下水实施限量开采前后及对盈余区加大开采后的效果观测资料分析，论述实施限量开采最主要的是首先选用均衡法求得地下水天然补给资源量，运用数值法求得可采资源量及其在含水层中的空间分布。其次运用地下水系统理论对研究区地下水资源进行调控，使地下水得到合理科学的开发利用。同时指出限量开采的实施将使由于过量开采地下水引起的不良水环境问题得以改善。
This paper expounds the definition of limited exploitation and the theoretical basis for determining the recoverable amount. Combined with the analysis of the effect data after the exploitation of limited exploitation and groundwater exploitation in the funnel area in Yongji City, the paper discusses the most important First, we use the equilibrium method to find the natural recharge resources of groundwater, and use the numerical method to find the recoverable resources and their spatial distribution in the aquifer. Secondly, using groundwater system theory to control groundwater resources in the study area, make the groundwater reasonable and scientific development and utilization. At the same time, it is pointed out that the implementation of the limited exploitation will improve the bad water environment caused by excessive exploitation of groundwater.
