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.
