摘要：Due to the many indicators affecting the health status of the Qijiang River, an evaluation system needs to be established for evaluation. According to the 12 indicators such as the degree of variation of the flow process in the indicator layer, Qijiang was evaluated. According to the survey, the main pollution of Qijiang water quality comes from domestic sewage, industrial sewage, mining and coal mining. Through the evaluation of the grading indicators and the gradual addition, Qijiang's comprehensive score is 48.09, and the river is in a sub-health state, and finally proposes a treatment plan.
