摘　　要：为了合理地评价浙江省“剿灭劣Ⅴ类水”的成果,采用2017—2020年浙江省地表水质日监测数据筛选出水质类别为6的频率最大的4个站点,应用单因子水质标识指数法和改进的综合水质标识指数法对监测数据的月均值进行综合评价。结果表明,自“剿灭劣Ⅴ类水”活动以来,这4个站点的水质总体上呈现出好转趋势,水质全部介于Ⅱ—Ⅴ类之间,但仍会出现超出相应的水环境功能区划标准的月份,甚至个别指标的单因子评价结果为劣Ⅴ类。In order to display the achievements of“eliminating 5 types of inferior water”in Zhejiang,based on the surface water quality data of four monitoring stations with the highest frequency of LevelⅥin Zhejiang from 2017 to 2020,the single factor water quality identification index method and the improved comprehensive water quality identification index method were used to comprehensively evaluate the monthly mean value of monitoring data.The results show that since the campaign of“exterminating 5 types inferior water”,the water quality of the four stations showed a trend of improvement,all the water quality is between LevelⅡandⅤ.However,there were some months beyond the corresponding water environment function zoning standards,even the single factor evaluation results of some indicators were inferior to LevelⅤ.
