岩溶地下水资源是解决西南地区缺水问题的重要水资源来源,但是岩溶地下水污染问题已经严重影响岩溶地区人民的生产和生活。目前的岩溶地下水污染研究主要集中在对地下水的化学污染方面,对于微生物污染的监测主要基于卫生学检测,而对其在环境中的行为特征少有研究。微生物污染是岩溶地下水污染研究的重要方面,对于岩溶地下水污染物运移及污染物控制有重要意义。该文以重庆市青木关典型岩溶地下河为例,对暴雨期间岩溶地下河出口的水文、水化学和微生物指标进行加密监测,研究该地下河的微生物污染程度及微生物污染物在岩溶地下河中污染质运移的示踪意义。结果发现,青木关岩溶地下河存在严重的微生物污染,且不同阶段地下河中的微生物污染物含量和污染物来源均不同。

Karst groundwater is the most important drinking water source for Southwest China,where however the water quality due to contamination has become too bad for local people's production and living.Most current researches on Karst groundwater contamination have focused on chemical contamination while monitoring on microbial contamination has mainly focused on hygienic tests.Seldom has any research be done on the behavior characteristics in environment.Microbial contamination is an important part of the research on Karst groundwater contamination,which is very significant for pollutants transfer and control of Karst groundwater.A typical Karst underground stream in Qingmuguan,Chongqing is chosen as an example in this paper for an encrypted survey on the hydrological,hydrochemical and microbial parameters at the underground stream exit during a storm event.The results show that the underground stream was seriously polluted by microbes and the content and source of microbial pollutants from one section of the stream were different from that of other sections.
