摘　　要：在全面认识苏锡常浅层地下水水文地质条件的基础上,对区内的各种与浅层地下水防污染有关的地质环境因素进行判别,选择含水层厚度、包气带岩性、水位埋深、含水层顶板厚度做为评价的4个因素,以G IS软件ArcInfo为主要工具,通过信息量的空间叠加分析,进行浅层地下水系统防污染性能评价。通过实际水质分析数据,验证了方法的合理性,旨在为加强浅层地下水资源管理提供指导。Based on a complete knowledge of the shallow groundwater conditions in Su-X-Chang Region, the authors distinguished the geoenvironmental factors related with shallow groundwater pollution-proof in the study region, four factors were chosen for evaluation： aquifer thickness, vadose lithology, water level burial and roof thickness of aquifer. The pollution-proof performance was evaluated based on GIS, and through a space superposition analysis of information and the rationality of the evaluation was validated by the practical water quality data.
