【摘要】 在资源型缺水城市，当无外来水源时，为满足城市日益增长的供水需求，决策者们常常选择超采地下水这一办法．尽管此举可能引发许多环境问题，但是在国内仍屡见不鲜．毫无疑问，如果继续超采地下水，完全可以想见，地下水资源最终将枯竭．本文研究了地下水枯竭现象、地下水枯竭的速度、深度、地下水枯竭产生的条件以及研究减缓地下水枯竭过程的对策措施．本文提出了地下水资源枯竭的概念及确定枯竭速度、深度和枯竭年限的计算方法并应用于大同市．所得结果，对于大同市地下水资源的开发和管理具有重要的指导意义．更多还原

【Abstract】 It is wellknown that the overdevelopment of ground water will result in many enviromental problems. If the ground water is being overdeveloped constantly, this kind of resource will be depleted. Therfore, it is necessary to study this phenonmenon, i. e. ground water depletion. After the concept of ground water resources depletion is defined, the rate depth and period of depletion, and the relative calculation method are studied in detail. Case studies, as that for Datong, show, that the result is satisfactory.更多还原
