山东省龙口市平原区地下水资源评价

GROUNDWATER RESOURCES EVALUATION OF THE PLAIN AREA OF LONGKOU, SHANDONG PROVINCE

采用迦辽金有限单元法对龙口市区地下水资源进行评价。按当地设计的开采量预报 ,本区未来地下水位降落漏斗范围有所缩小 ,地下水位负值区面积基本没有变化。只有采取如下措施 :增开新的水源地 ,充分利用地表水及加强水库工程 ,合理布局开采井 ,再生水利用及引进容水 ,方能达到最优的环境和社会效益。

This paper presents the evaluation of the groundwater resources in the plain area of Longkou by using Galerkin Finite Element Method. According to the designed water exploitation amount, we have predicted the trend of the groundwater level fluctuation in the study area. The study shows that the drawdown area still remains even though the groundwater level has the tendency of rising again in the hoper area. To meet the most optimum environmental and social benefits in the study zone, there is a need to take the following measures: developing new water source regions, using efficiently surface water and reinforcing water reservoirs engineering, Locating adequately pumping wells, reusing waste water and importing supplementary water resources.
