以重庆市南山老龙洞地下河流域为研究单元，通过主成分分析和实地调查，研究该区域人类活动对岩溶地下水水质的影响，并探讨污染物的来源。结果表明，受城镇区人类活动影响，老龙洞地下河流域地下水 NO3--N和PO43--P污然最为严重，按 GB5749-2006规定，研究区的地下水已不可作为饮用水源。老龙洞地下河水NO3--N含量逐年在减少，而PO43--P却在增加，赵家院子泉水PO43--P增长也十分迅速，老龙洞地下河流域地下水受城镇化影响越来越明显。老龙洞地下河水受城镇人类活动、工业活动、农业活动的共同影响，污染比泉水严重。老龙洞地下河中NO3-和SO42-含量的减少，说明采取一些积极的措施，地下水的污染是可以得到治理的。

By analyzing principal components and field survey data of subterranean rivers flow through Laolongdong in Chongqing Nanshan, the impact of human activities on karstic groundwater quantity and the source of contaminant are studied in this paper. Results shows that groundwater in the studied area has heavy pollution of NO3 - -N and PO4 3- -P because of human activities and can not be used as drinking water according to GB5749 -2006. The yearly reduction of NO3 - -N con-tent and the increase of PO4 3- -P content embody the sever impact of urbanization. Groundwater under and around Laolong-dong, which is badly affected by human activities, industrial activities and agricultural activities, has much more serious pol-lution problems than spring in this region. The reduction of NO3 - -N content indicates that pollution could be under control with active measurements.
