【摘要】 苏锡常地区超量开采深层地下水已引起严重的地质灾害问题,在当前严禁开采深层地下水的形势下,浅层地下水系统水资源的分布及可开采资源量的大小就显得十分重要,需要对该地区浅层地下水资源量进行评价,查明其可开采资源量。通过对苏锡常地区浅层地下水水文地质背景条件的研究,划分了多个浅层地下含水子系统,分析了各子系统的补径排条件,建立了整个浅层地下水系统水流的数值模型(GMS)。在给定的基本水位约束条件下,苏锡常地区浅层地下水系统可持续开采的水资源量每年可达到10．57×10~8m~3。更多还原

【Abstract】 Serious geologic hazards have been caused by excessive exploitation of the deep groundwater for a long period in the Suzhou- Wuxi-Changzhou area of Jiangsu Province.For this reason,the government has delivered a ban on pumping the deep groundwater.Therefore,it is important to evaluate the shallow groundwater resources in the study area.This paper gives brief preliminary results and information about shallow groundwater system,including water bearing structure,distribution pattern,supply sources,runoff and drainage.Then an uniform model of groundwater flow in the shallow aquifer has been remade considering the whole study area.Groundwater of exploitable water resources in this area are forecasted with the calibrated model by restricted water level which is of referential value for making water resources development plan and water supply in the area.更多还原
