| 摘 要： | 三峡水库蓄水以后，为了研究三峡库区水质如何变化这一国内外广泛关注的问题，通过对三峡水库重庆段近几年水质数据的分析，采用季节性Kendall检验法分别对库区干流6个水质监测控制断面和主要支流的3个代表断面近6 a（2003~2008年）的主要污染指标总磷、高锰酸盐指数和石油类进行水质趋势分析。结果显示，库区江段水质参数浓度趋势以下降变化为主，总体水质状况6 a来基本趋于好转；库区重庆江段受总磷污染较为严重，且以呈上升变化为主，应加强对其污染源的控制和治理。

| Abstract: | After the impoundment of Three Gorges Reservoir,in order to study the water quality variation tend of the reservoir area,which is an attention-attracting issue at home and abroad,the water quality trend of TP,CODmn and petroleum at 6 cross-sections of the main stream and 3 cross-sections of the main tributaries is analyzed with the seasonal Kendall method by using the water quality data of Chongqing reach in recent years(from 2003 to 2008).The analysis results show that the pollutant concentration has a dow... |
