大同市区二十年地下水动态研究

本文首先分析了大同市地下水开采与地下水降深之间的对应关系，同时分析了影响地下水动态的其它因素，然后将地下水开采和大气降水量这两个影响地下水动态的主要因素与地下水动态进行复相关计算，求出相关方程，并进行不同开采量的地下水降深预测，最后根据这些地下水动态研究结果提出了解决大同市水问题几项对策建议。本文的研究结果同时表明，地下水动态研究非常必要且现实意义明显。通过动态变化可以了解地下水的补排及储水介质的变化情况，利用动态变化规律可以预测水文地质条件的变化趋势，根据地下水动态变化特点可采取有针对性的、灵活的取水方案。可以说，地下水动态研究成果在水资源的开发、利用、保护中具有极大的可利用价值。

Study on Groundwater Regime over the Past 20 Years in Datong urban district

The article first analyzed the correlation between groundwater exploitation and draw-down as well as other elements which also affect groundwater regime, then does the multiple correlative calculation between ground water exploitation and atmospheric precipitation the two main affecting elements and ground water regime, obtained the multiple correlation equation, then carried on the forecast about groundwater draw-down according to different exploiting amount. Finally proposed some suggestions and counter measures on how to solve water problems in Datong City. The research results shown that it is essential to carry on groundwater regime research and with obvious practical significance. Through the variation of groundwater regime, we can know the ground water recharge and discharge and the variation of water storage. Using the rule of regime variation enable to forecast the change tendency of hydro-geological condition. According to the change peculiarity, we can take counter and flexible water exploitation schemes and optimized use of groundwater. The research results of groundwater regime have a great utilizable value in the exploitation, utilization and protection of water resource.
