| 摘 要： | [目的]评价汾河运城段水质情况。[方法]运用主成分分析法(PCA)对2015年汾河运城段的水质进行评价。[结果]在选取的4个指标PH、COD、DO和NH_3-N中,NH_3-N为主要污染因子;在全年45个监测周中,水质情况总体表现为丰水期优于枯水期。[结论]汾河运城段水质处于国家劣V类,须采取相应的手段控制污染,改善水质。

| Abstract: | Objective] To evaluate water quality in the Yuncheng section of Fenhe River.[Method] Water quality in the Yuncheng section of Fenhe River in 2015 was evaluated by using principal component analysis ( PCA).[ Result] Among the four indicators including pH, COD, DO and NH3-N, NH3-N was the main pollution factor.In the 45 monitoring weeks in 2015, the water quality in the wet season was gen-erally better than that in the dry season.[Conclusion] Water quality in the Yuncheng section of Fenhe River was worse than Grade V, so it is needed to adopt corresponding measures to control water pollution and improve water quality . |
