摘　　要：本文以西南岩溶山区遵义市燕子洞地下河系统为例,在全面阐述研究区水文地质条件基础上,结合水文环境地质调查、示踪试验、地下水特征污染分析及水质动态监测成果进行综合分析,归纳总结提出了遵义市燕子洞地下河污染模式为间歇性直排灌入型污染,在西南岩溶山区地下河系统污染模式中较为典型,该污染模式的建立对西南岩溶山区地下水污染物的运移规律、污染羽分布范围及污染动态变化特征的认识具有重要意义,为西南岩溶山区地下水污染防治提供重要的借鉴意义。Taking the Yanzidong underground river system in the Southwest Karst Mountains of Zunyi as an example, based on a comprehensive description of the hydrogeological conditions in the study area, combined with hydrogeological survey, tracer test, groundwater characteristic pollution analysis and water quality dynamic monitoring results, a comprehensive analysis is made. It is concluded that the pollution model of Yanzidong Underground River in Zunyi is intermittent direct drainage and irrigation, which is typical in the underground river system of karst mountain area in southwest China. The establishment of the pollution model is of great significance to the understanding of the transport law of groundwater pollutants, the distribution of pollution plumes and the characteristics of pollution dynamic change in the karst mountain area of southwest China, it provides important reference for the prevention and control of groundwater pollution in karst mountain area of southwest China.
