摘　　要：岩溶地下水资源是西南地区社会和经济发展的重要保障,随着城市化进程的不断加快,西南地区岩溶地下水污染问题也日益凸显,直接威胁当地群众的健康安全,已成为社会热点。以西南地区典型岩溶地下水系统污染实例为研究对象,通过分析每个岩溶地下水系统污染实例的水文地质条件、污染源特征、污染物迁移规律及污染危害等方面,归纳总结西南地区典型岩溶地下水系统污染模式,分为四种:间歇型入渗污染、持续型入渗污染、灌入型污染和越流型入渗污染。该项研究便于识别污染物的运移特征及规律、掌握污染范围和污染程度,为西南岩溶地区地下水污染物的防治工作提供重要的借鉴意义。Karst groundwater resource is an important guarantee for the social and economic development in southwest China.With the continuous acceleration of urbanization process,the problem of karst groundwater pollution in southwest China is becoming increasingly prominent.Posing direct threats to the health and safety of the local people,it has become a hot social issue.In this paper,we studied the typical karst groundwater system pollution cases in southwest China.Through the analysis of the hydrogeological conditions,characteristics of pollution sources,law of pollutant migration,and pollution harm of each karst groundwater system,we summarized the typical karst groundwater system pollution models in southwest China,including intermittent infiltration pollution,continuous infiltration pollution,pouring pollution and leakage infiltration pollution.This study can help researchers to better identify the characteristics and laws of pollutants transport,and more accurately grasp the scope and extent of pollution.It can provide important reference for the prevention and control of groundwater pollutants in karst areas in southwest China.
