摘　　要：利用平均综合污染指数和秩相关系数法,对“十二五”至“十三五”期间安阳市地表水环境质量状况进行了综合分析。结果表明:“十二五”至“十三五”期间,安阳市河流各污染因子下降趋势的显著性顺序为:氨氮>总磷>化学需氧量>高锰酸盐指数>生化需氧量,除生化需氧量外,均呈现显著下降趋势;近10年来,安阳市河流Ⅰ~Ⅲ类断面比例呈显著上升趋势,劣Ⅴ类断面比例呈显著下降趋势,“十三五”期间,河流断面水质Ⅰ~Ⅲ类占比增加43.5%,劣Ⅴ类占比下降47.8%,5年间劣Ⅴ类水体呈显著下降趋势,尤其是2020年劣Ⅴ类断面消除,整体水环境质量显著好转,但安阳市地表水污染属于典型的有机型污染。分析了安阳市水环境污染与治理现状,提出了相应的治理对策,为解决安阳市水环境问题提供有力支撑。The average comprehensive pollution index and spearman correlation coefficient method are used to comprehensively analyze the water quality of Anyang City from the 12th to 13th Five-Year Plan.The results show that during the period from the 12th to 13th Five-Year Plan,the order of the downward trend of river pollution factors in Anyang City is ammonia nitrogen>total phosphorus>chemical oxygen demand>permanganate index>biochemical oxygen demand,which shows a significant downward trend except biochemical oxygen demand;In recent ten years,the proportion of class I~Ⅲriver sections in Anyang City has shown a significant upward trend,and the proportion of inferior class V sections has shown a significant downward trend.During the 13th Five-Year Plan period,the proportion of class I~Ⅲriver section water quality has increased by 43.5%,and the proportion of inferior class V has decreased by 47.8%.In five years,the proportion of inferior class V water body has shown a significant downward trend,especially the elimination of inferior class V sections in 2020,and the overall water quality has improved significantly,but the surface water pollution in Anyang City is a typical organic pollution.This paper analyzes the current situation of water pollution and treatment in Anyang City,and puts forward the corresponding treatment countermeasures.This research will provide support for solving the water environment problems in Anyang City.
