摘    要:根据对1999年长江三峡库区10个主要城市江段的12个监测断面(不考虑大肠菌群时为16个断面)的水质监测结果,采用综合污染指数法(P值法)对各监测断面、城市江段以及库区总体水环境质量进行了综合评价.结果表明,库区水质主体上是属于轻度污染,少数水域属于中度污染,个别情况下有重污染;主要污染区域为重庆主城区、长寿、涪陵和万州;主要污染物是大肠菌群、TP、非离子氨和石油类.

关 键 词:三峡库区  水质  评价  P值法

Abstract:One year water quality monitoring results of 16 sections alongside the Three Gorges Reservoir area were presented. From the evaluation carried out using the integrated polluted index (P value), some characteristicses of the water quality were obtained. The results showed that water quality of the Three Gorges Reservoir area was slightly polluted in 1999 mainly because of the discharge of urban sewerage and industrial wastewater. Main polluted city sections were along the river banks of Chongqing , Changshou, Fuling and Wanzhou. Evaluation also showed that there were 4 indicators that, to different extent, affected the water quality: colon bacillus, TP, non ionic ammonia and oils.
Keywords:Three Gorges Reservoir area  water quality  evaluation  P value
