摘　　要：地表水水质评价是区域水资源管理与水污染防治的基础。本文利用牟汶河莱芜(三)水文站控制断面2008-2018年的水质监测数据,采用内梅罗污染指数法和单因子评价法对牟汶河的水质状况进行评价,基于水质评价结果,采用Mann-Kendall趋势检验法对水质变化趋势进行分析。结果表明:(1)莱芜(三)水文站以上牟汶河河段总氮的污染指数均大于1,总磷指数也存在多年大于1的情况,总氮超出Ⅳ类水质标准2.8-9倍,总磷在2011-2014年分别超出Ⅳ类水质标准1.03和1.6倍,水质情况较差;(2)莱芜(三)水文站以上牟汶河河段汛期和非汛期的水质整体处于中度污染,非汛期污染指数高于汛期;(3)总体上莱芜(三)水文站以上牟汶河河段水质状况不断好转。Surface water quality evaluation is the foundation of regional water resources management and water pollution prevention.Based on thewater quality monitoring data in 2008-2018 of the control section of the Muwen River Laiwu(3)Hydrological Station,The paper uses Nemerow pollution index method and single factor evaluation method to evaluate the water quality of Mouwen River.Combined with the results of water quality evaluation,the paper adopts the Mann-Kendall trend test method to analyze the trend of water quality changes.(1)The results show that the pollution index of total nitrogen is greater than 1,and the total phosphorus index has been greater than 1 for many years in the Muwen River section above the Laiwu(3)Hydrological Station.In addition,the total nitrogen exceeded the Type IV water quality standard by 2.8-9 times,and the total phosphorus exceeded the Type IV water quality standard by 1.03 and 1.6 times respectively in 2011-2014 in the Muwen River section above the Laiwu(3)Hydrological Station.The water quality of this section is poor.(2)The results show that the non-flood season pollution index is higher than that in the flood season,and the water quality during the flood season and non-flood season is generally at a moderate level of pollution in the Muwen River section above the Laiwu(3)Hydrometric Station.(3)On the whole,the water quality of the Mouwen River section above the Laiwu Hydrological Station(3)has continued to improve.
