汾河水质状况研究

摘要

Based on the common monitoring data of 21 sections along the Fenhe River in 10 years, this study selected five main pollution indexes and analyzed the changing tendency of water - quality in the upper, middle and lower reaches of Fenhe River by using comprehensive water - quality index. The status and characteristics of water - quality and pollution were discussed by analyzing the change of water - quality along the river and the change of several important water - quality indexes. This paper summarized the changing tendency of the main pollution indexes, discussed the reasons of water pollution and improvement ac- cording to practical pollution situation in Fenhe. Some suggestions on the further improvement of water environment quality of Fen- he River were also put forward.%通过对十年来汾河沿程21个断面的常规水质监测数据进行整理分析，筛选出5项主要污染指标，采用综合水质指数法分析汾河及上、中、下游各河段水质变化趋势，运用沿程水质变化和几个重要水质指标的比值变化分析汾河水质状况和污染特征，总结主要污染指标的变化趋势，结合汾河流域实际排污情况探讨水质污染和改善原因，并对进一步改善汾河水环境质量提出建议。
