Abstract
Selecting water quality data from the water resources quality monitoring sections in Suzhou City from 2021 to 2025,the main pollutant factors are dissolved oxygen,permanganate index,chemical oxygen demand,five-day biochemical oxygen demand,ammonia nitrogen,and total phosphorus.The single factor evaluation method and Nemerow index method were used to analyze the trend of water quality changes.The results of the single factor evaluation indicate that the proportion of excellent Class Ⅲ monitoring sections in Suzhou City continued to increase from 2021 to 2025;according to the analysis using the Nemerow index method,the Nemerow index value of the exceedance factor shows a downward trend on both annual and monthly scales.关键词
