摘　　要：本文通过对2018—2023年资阳市安岳县姚市河水质变化特征进行分析,弄清了河流主要污染成因,有针对性地提出了水质改善建议,推动了水质的持续改善。利用单因子评价法、综合污染指数法、Spearman秩相关系数法,分析研究了姚市河水质变化规律。结果表明:2018—2023年姚市河水环境质量总体呈平稳向好的趋势,主要监测指标呈显著下降趋势,主要污染物为化学需氧量、高锰酸盐指数。建议从完善污水处理基础设施、强化农业面源污染管控方面对姚市河流域进行综合治理,全面推进安岳县姚市河地表水环境质量稳定达标。The analysis of water quality variation characteristics of the Yaoshi River in Anyue County,Ziyang City,from 2018 to 2023,aims to identify the main causes of river pollution and propose targeted suggestions for water quality improvement,thereby promoting continuous water quality enhancement.Using the single-factor evaluation method,comprehensive pollution index method,and Spearman rank correlation coefficient method,the study analyzes the water quality variation patterns of the Yaoshi River.The results indicate that the overall water environment quality of the Yaoshi River showed a stable improvement trend from 2018 to 2023,with a significant decrease in major monitoring indicators.The main pollutants were chemical oxygen demand and permanganate index.It is recommended to comprehensively manage the Yaoshi River basin by improving sewage treatment infrastructure and strengthening the control of agricultural non-point source pollution,to ensure the stable compliance of surface water environmental quality in the Yaoshi River of Anyue County.
