VULNERABILITY TO CONTAMINATION OF GROUNDWATER IN URBAN REGIONS

摘要: 地下水污染敏感性分析与制图是目前国际上水文地质工作的热点.总结了过去所用的评价方法, 在GIS平台上根据我国城市的实际情况, 对原有的DRASTIC模型加以开发改进, 提出了DRAMIC模型并加以解释, 以作为我国统一的城市地下水污染敏感性分析的通用指标.最后介绍了如何用GIS来作地下水污染敏感性分区图.Abstract: The evaluation and mapping of the groundwater vulnerability to contamination are of primary importance for hydrogeological studies. In this paper, the traditional methods are reviewed and a new DRAMIC model is presented by improving the DRASTIC model to make it suitable for the hydrogeological conditions of urban areas in China. The model DRAMIC can be used as a general index system for evaluating the vulnerability of groundwater to contamination in Chinese cities. In the final part of this paper, is introduced the method for the application of GIS to the mapping of the DRAMIC model.
