摘　　要：对粤北某地下河系统选取4个典型岩溶水点作为取样点,结合系统内垃圾填埋场、养殖场及废弃洗矿场等污染源对地下河水质状况影响进行分析评价,并在雨季暴雨后再次对这4个岩溶水点进行取样分析,对比干旱期与暴雨后不同降雨条件下地下河水质变化情况,分析污染状况。最终从系统地下河总出口水质分析得出,该地下河系统在干旱期能有一定自净能力,但在暴雨后水质受上游污染源的影响就较大。Four typical karst water points are selected as sampling points for an underground river system in northern Guangdong. The influence of waste landfill, aquaculture farm and waste washing yard on the water quality of underground river was analyzed and evaluated. The four karst water points were sampled and analyzed again after rainstorm in rainy season. The water quality changes of underground rivers under different rainfall conditions during drought period and after rainstorm were compared, and the pollution status was analyzed. Finally, from the water quality analysis of the total outlet of the underground river system, it can be concluded that the underground river system has a certain self-purification capacity during the drought period, but the water quality is greatly affected by the upstream pollution sources after the rainstorm.
