Study on Water Quality Evaluation of Reservoirs in Xinhui District,Jiangmen from 2011 to 2021 and Land Impact
摘要
Abstract
The impact of water quality eutrophication status and land use type of reservoirs in Xinhui District,Jiangmen from 2011 to 2021 was evaluated by using the single factor method,the comprehensive trophic status index method and remote sensing interpretation,in order to provide a basis for the protection of reservoir water resources.The data showed that:①The water quality of the reservoirs in the study area was mainly class II to III,and the water quality was maintained very well,and the reservoir as a whole was in the category of poor trophic to medium nutrition;②The heavy metals and phenolic substances in the reservoir were class I or not detected all year round,and the water quality changes were mainly closely related to TN,TP,nitrogen-phosphorus ratio and CODMn;③There was a certain correlation between the transparency,chlorophyll a,dissolved oxygen,Zn,Cu and land type of the reservoir in the downstream of Yamen waterway.The above results reflect that the water quality of the reservoirs in Xinhui District is generally stable and good,and the water quality of the reservoirs around Yamen Waterway exceeds the standard due to the influence of sewage discharge from surrounding factories,and the nutrient of water bodies has an aggravating trend.关键词
