摘　　要：温峤下山头桥是温岭市的国控断面。以2018年为例,采用每月总磷、高锰酸盐指数、氨氮、化学需氧量等数据,运用灰色聚类法和内梅罗污染指数综合评价河道水质,并将溶解氧变化和灰类变化结合起来获取连续时段的水质变化趋势,进而预测水质灰类。深入剖析了降雨量与总磷、高锰酸盐指数、氨氮、化学需氧量等污染因子月变化的联系,找出可能影响断面稳定达标的主要因素。Wenqiao Xiashantou Bridge is the national control section of Wenling City. Take 2018 as an example, the monthly data of total phosphorus, permanganate index, ammonia nitrogen, chemical oxygen demand were used, and comprehensive evaluation of river water quality by grey clustering method and Nemerow pollution index were made. The change trend of water quality was obtained by combining the change of dissolved oxygen and grey category, and furthermore the grey class of water quality was predicted. The relationship between rainfall and monthly variation of total phosphorus, permanganate index, ammonia nitrogen and chemical oxygen demand was analyzed in order to find out the main compliance factors that might affect the stability of section.
