Analysis of Water Environment Quality in Luding County Section of the Dadu River
摘要
Abstract
In order to master the overall water environment quality and trends of the Dadu River in Luding County and better protect the water quality at the beginning of the middle reaches of the Dadu River,it is important to propose more specific water pollution prevention and control measures.Based on routine monitoring data of water quality at the upstream and outlet sections of the Dadu River in Luding County,the single factor index method,Nemerow index method,and Spearman rank correlation coefficient method were used to analyze and evaluate the water quality of the Dadu River in Luding County.The results showed that from 2018 to 2022,the water quality at the exit section of Luding County was better than that at the upstream section of the entry.The water quality at the exit section of Luding County was increasing year by year,and the water quality tended to stabilize in 2021,The concentration of total phosphorus and permanganate index were as follows:wet season＞normal water level period＞dry season,and the water quality in June to August was relatively poor.From 2017 to 2022,the concentration of permanganate index in its exit section showed a significant downward trend.Systematic analysis on water quality and change trends of in Luding county section of the Dadu river can provide data support to local governments to carry out environmental protection work for the Dadu River.关键词
