摘　　要：为探究承德地区主要水系水质状况及污染特征,选取承德市地表水水质监测站2017~2020年29个断面监测数据,采用单因子评价法、综合污染指数法和主成分分析法对承德地区主要水系水环境质量进行综合评价。评价结果表明,总体来看2017~2020年承德地区主要水系整体水质较好;从时间上来看,2019、2020年承德地区主要水系水质较2017、2018年有较为明显提升;从空间上来看,宫后和承钢大桥断面污染相对较为严重。承德地区水系水质主要受总磷、COD和高锰酸盐指数影响较大。In order to explore the water quality and pollution characteristics of the main water system in Chengde area,the monitoring data of 29 sections of Chengde surface water quality monitoring station from 2017 to 2020 were selected,and the water environment quality of the main water system in Chengde area was comprehensively evaluated by single factor evaluation,comprehensive pollution index and principal component analysis.The evaluation results show that generally speaking,the overall water quality of the main water system in Chengde is good from 2017 to 2020;From the perspective of time,the water quality of the main water system in Chengde in 2019 and 2020 was significantly improved compared with 2017 and 2018;From the perspective of space,the section pollution of Gonghou and Chenggang bridges is relatively serious.The water quality of the main water system in Chengde is mainly affected by the total phosphorus,COD and permanganate index.
