摘要
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 .关键词
