Abstract
Based on the monthly monitoring data of water quality in 2016,the water quality and eutrophication status of the reservoir were evaluated by single factor evaluation and comprehensive nutrition state index method,and the correlation of main environmental factors and the reservoir pollution sources were analyzed.The results showed that the general water quality of Mei Wan reservoir was class IV,the exceeding pollutant was TP,and belonged to mild pollution level.In November,the water quality meet class Ⅲ standard,while in the remaining months it meet class Ⅳ standard.TN was in the inferior class Ⅴ level throughout the year.Reservoir in winter and spring was medium? eutrophic,and in summer and autumn was mildly eutrophic,overall it was in a mild eutrophic state.There was a very significant correlation between chl-a,water temperature and CODMn,but the correlation was not significant between P and N.There was significant positive correlation between TN,CODMn and water temperature.Meanwhile,we put forward environmental remediation proposals to the pollution sources in the reservoir area.关键词
