摘　　要：目前我国已经进入快速城市化阶段,城市化的同时产生的生活污水及废弃物不断增加,对环境的污染加剧。为了了解人类活动尤其是城市化对岩溶地下河水质的影响,对重庆市南山老龙洞地下河流域上游的污水和老龙洞地下河出口处的河水的温度、pH、电导率、溶解氧和阴阳离子等水化学指标进行了一年的连续性观测。结果表明,老龙洞地下河的主要污染源是上游城镇产生的生活污水,各项指标都超过了国家地下水质量标准,急需治理。At present our country has entered the stage of rapid urbanization, at the same time sanitary sewage and waste is increasing and the environmental pollution is aggravating. In order to understand human activities especially the effection of urbanization on the water qualitative of karst subterranean river. An observation on the water chemical index of Laolongdong subterranean river＇s outlet and it＇s upper reches sewage had been carried through continuously in a year, such as water temperature,pH, electrical conductivity, dissolved oxygen and the positive and negative ions.The results show that the main pollution sources of the Laolongdong underground river is from the upstream sewage of the town,and all the indexes are worse than the National Groundwater Quality Standards, and the water of Laolongdong subterranean river is in urgent need of management.
