摘　　要：为有效预防岩溶地区能源化工企业地下水污染,采用PI(保护层和渗透条件)法对我国西南岩溶地区某煤化工项目拟建场址周边地区的地下水防污性能进行评价。结果表明:根据地下水防污性能可将研究区分为防污性能很高区、防污性能高区、防污性能中等区和防污性能低区,各地下水防污性能分区与研究区的地层岩性和地下水埋藏条件具有较好的空间分布一致性。根据评价结果提出选址布局优化方案和分区防渗建议,可为该项目高效开展地下水污染预防工作提供参考。In order to effectively prevent groundwater pollution of energy chemical enterprises in karst area, PI(protective layer and infiltration condition) method was used to assess the groundwater vulnerability of the surrounding area of a coal chemical project in karst area in Southwest China. The results showed that the groundwater vulnerability of the study area were divided into very high vulnerability area, high vulnerability area, medium vulnerability area and low vulnerability area, and the groundwater vulnerability had good spatial distribution consistency with the formation lithology and groundwater burial conditions in the study area. Based on the assessment results, the optimization scheme of site layout and the suggestions of zoning seepage prevention were proposed, which could provide reference for the efficient groundwater pollution prevention work of the coal chemical project.
