基于地下水安全的采补均衡曲线研究

Research on Exploitation and Recharge Equilibrium Curve Based on Groundwater Supply Security

通过对吕梁市平川区地下水补给规律及开采规律的分析,概化出地下水补给曲线、开采曲线,提出了补给量的变动、补给的变动、开采量的变动、开采的变动的概念。应用地下水补给量和开采量随降水量增减变化呈互逆变化的特征,提出了地下水采补均衡曲线,为划定地下水开采量的安全性提供了计算依据,对提高区域地下水资源供给安全保障具有现实意义。

Groundwater recharge and exploitation variation of the Pingchuan District in Lvliang City were analyzed for plotting the recharge curve and the exploitation curve of ground water. Definitions including recharge amount variation,recharge variation,exploitation amount variation,exploitation variation were proposed. Characteristics that the recharge and exploitation amount of ground water varied inversely with the precipitation were used to present the exploitation and recharge equilibrium curve of ground water. The results could provide calculation basis for determining the safety of groundwater exploitation amount, and could improve the regional groundwater supply security.
