TTo explore the status quo of water quality of Xichong River and its characteristics as well as to provide water quality control measurements for small river basin similar to the Xichong River elsewhere,an analysis of water quality of Xichong River was carried out according to the monitoring data for the past five years with regards to KMnO_4,TP,COD and NH_3-N from five monitoring sections,among which the Chairongqiao monitoring section is the only control section at provincial level and was the focus for the analysis. The results show that: in the past five years,although the average monthly and annual evaluation results of Xichong River are in the state of incomplete compliance with water quality standard,the indicators are in the form of tortuous improvement with the comprehensive river regulation being underway along Xichong River,among which annual monthly average of NH_3-N satisfied the requirement of relevant water quality standard in 2015. Therefore,water quality of Xichong River will be not far away from standard compliance in the years to come.
