摘要：

为了明确彰武水库环境质量状况,依照功能区对水质的要求和2009—2015年的实测水质数据,通过单因子水质标识指数法、综合污染指数法、有机污染指数法来评估其水环境状况,结果表明：（1）TN是该水库的主要污染因子,仅有4个月份能满足水质要求,其年均单因子水质标识指数都大于6;其次是TP,有53个月份水质超标,其年均单因子水质标识指数除2013年外均超标。（2）根据综合污染指数,该水库仅有5个月份水质合格,其他月份则处于污染状态,其中有39个月份为重度污染,这导致其年均和水期污染指数在污染与重度污染之间变化。（3）依据有机污染指数,有7个月份水质为基本合格,其他月份水质在较好与良好之间变动,没有发生有机污染;其年均和水期有机污染指数在较好与良好之间变化,有向水质恶化方面发展的趋势。

Abstract:

Three methods were applied to water quality assessment for Zhangwu reservoir, including the single factor water quality identification index, comprehensive pollution index and organic pollution index methods, so as to know its environmental quality status. The assessment was based on water quality data from 2009 to 2015 and water quality requirements. The results suggested that (1) TN was the main pollution factor in the reservoir, it could meet the requirement of water quality for only four months, and its annual single factor water quality identification index was greater than six; TP was the second factor exceeding the standard of water quality in 53 months, and its annual average index could not meet the requirement except in 2013; (2) from the perspective of comprehensive pollution, the water quality of only five months in the reservoir was qualified and that of the rest months were in pollution, with severe pollution in 39 months, which resulted in the pollution index of annual average and water phase changing between pollution and severe pollution; (3) from the perspective of organic matter pollution, the water quality of the reservoir changed between the grade of good and relatively good, and that of 7 months was basically qualified, there was no organic pollution; the organic pollution index of annual average and water phase varied between the level of good and relatively good, and there was a tendency to organic pollution.

Key words: Zhangwu reservoir, environmental quality, water quality, single factor water quality identification index, comprehensive pollution index, organic pollution index, assessment
