摘要
本研究以2016-2020年宿迁市省控以上地表水断面(点位)监测结果为依据,分析水质变化趋势。研究表明,2020年宿迁市水质优良比例(Ⅰ~Ⅲ类)为92.3%,水质优良比例逐年上升,主要污染物为化学需氧量、氨氮、总磷。"十四五"时期,要围绕"保好水、治差水、排尾水"的总体思路,以水环境质量改善为核心,聚焦突出短板,推进水环境、水资源、水生态协同共治。
Based on the monitoring results of surface water sections(points)above provincial control in Suqian City from 2016 to 2020,this study analyzes the trend of water quality changes.Research shows that in 2020,the proportion of good water quality in Suqian City(classⅠtoⅢ)is 92.3%,and the proportion of good water quality is increasing year by year,the main pollutants are chemical oxygen demand,ammonia nitrogen and total phosphorus.During the"14th Five-Year Plan"period,it is necessary to focus on the overall idea of"preserving water,treating poor water,and draining tail water",focus on improving the quality of the water environment,focus on highlighting shortcomings,and promote the coordinated and co-governance of water environment,water resources,and water ecology.
