摘　　要：基于浏阳河梨、黑石渡和三角洲断面2005年1月—2018年11月水体中每月21项监测指标数据,通过评价函数构造与综合打分、改进层次分析法以及模糊综合评价法对浏阳河水质进行评价。结果表明:在167个考察月份内,梨断面综合水质状况最优且长期保持相对稳定,黑石渡和三角洲断面水质相对较差且波动较大,特别是在枯水期与平水期水体污染较为严重,为IV类,且主要为无机污染。但是,2008年以来,随着水污染综合整治政策的实施,黑石渡与三角洲断面水质得到明显改善。因此,科学有效的水质评价,能够客观反映水环境质量状况及其变化趋势,可以为浏阳河流域水质监测与污染防治提供参考。Based on monthly data of 21 monitoring indicators of Langli,Heishidu and delta sections of Liuyang River during the period of January 2005 to November 2018,the water quality assessment was performed by the methods of comprehensive evaluation function,improved analytic hierarchy process(AHP),and fuzzy comprehensive evaluation.The results showed that during the 167 months investigated,the comprehensive water quality in the Langli section was the best and remained relatively stable for a long time,while the water quality in Heishidu and delta sections was relatively bad and fluctuated greatly,especially in the dry season and normal season,the waterbody was seriously polluted mainly by inorganic pollution,falling into class IV.However,since 2008,with the implementation of the comprehensive water pollution control policy,the water quality of Heishidu and delta sections has been significantly improved.Thereforce,scientific and effective water quality assessment can objectively reflect the water environment quality and its change trends,and provide reference for water quality monitoring and pollution prevention and control of Liuyang River Basin.
