中文摘要：

泰安市东武水源地近年来由于开采逐年增加、河床挖沙等因素的影响，水源地附近地下水环境出现了水位下降、水质退化等环境地质问题。利用水源地开采区及周边地区环境地质调查的基础数据，运用GMS（Groudwater Modeling System）对水源地及周边地区的地下水流运动及地下水溶质运移进行了数值模拟，结果显示由于水源地长期开采岩溶水，开采中心形成了明显的地下水降落漏斗，但是要现状开采条件下水源地及周边地区短期内不会出现严重的环境地质灾害。此外，由于河沙掠夺式开采的影响，水源地岩溶水补径排条件发生了改变，水源地地下水水质受地表水影响明显，需要引起足够的重视。

英文摘要：

Due to the increase of water pumpage and the sand excavation at the river bed,the groundwater table be-came declined and water quality degraded in Dongwu water sources area, Tai＇an City. This article, Based on the environmental geology survey data, and used GMS, simulated the groundwater flow and solute transfer. The result shows that because of the longtime mining of karst water, the cone of depression became obvious. However, there are no serious environmental and geologic hazards under the present mining conditions. Affected by the bed sand excavation, the hydrological condition changed a lot. So, the groundwater quality has obviously related with the surface water, and it will be paid much attention.
