  • Some different methods for lake trophic status evaluation were compared based on lake eutrophication index screening, and the preliminary proposal values of the lake nutrient water quality standards developed, in order to provide scientific basis for better control and management of lake eutrophication. Comprehensive trophic status index method and chlorophyll-a content classification method were respectively combined with frequency distribution method in statistics to evaluate the nutrition status of Fuxian Lake. The results showed that the two methods had little difference in evaluation standards and their effects on total environmental capacities were little. After comparing the application scopes of the two methods, nutrient standards were determined. Fuxian Lake belonged to poor nutrient lake, and the nutrient standards of Chl-a, TP, TN, and SD were 1.600 mg/m3, 0.006 mg/L, 0.173 mg/L, and 7.000 m respectively.
