The results showed that the water of grade I accounted for a high proportion, with mild pollution and strong self-cleaning ability; the pollutants(e.g. ammonium nitrogen, total phosphorus and fluoride) at each section mainly came from phosphate mines and phosphorus chemical companies; and the water quality among different sections was in the order Chayuan, Xingren Bridge, Xiasi, Locomotive Section, Yingpan, Panghai(from superiority to inferiority). This study has important reference values for improving the water environment, safeguarding the safety of drinking water supply and scientifically preventing and controlling water pollution in the basin.展开更多
