Starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well-studied determination method of determining the two hydrographical coefficients: rainfall infiltration replenishment rate and irrigation replenishment rate. Then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage,exploitation on water regulation. After analyzing the adaptability of molepipe drainage, an underground water table regulation is given out.
论文从灌区的地下水资源及其可开采量评价分析方面入手，在对两个主要的水文地质参数即降雨入渗补给系数、灌溉入渗补给系数确定方法研究的基础上，对灌区的地下水资源状况进行分析，依据灌区的灌溉、降雨、排水条件及各种现状因素，建立了地下水资源量计算的数学模型，西安理工大学工程硕士专业学位论文计算得到青铜峡灌区地下水的最大补给量和可开采量；另外对在开发利用地下水资源过程中的地下水位的调控进行了初步的探讨，在银北灌区开展对暗管排水调控地下水位的试验研究。
