Abstract
In September and November 2022,the phytoplankton and physicochemical indexes of 3 sampling sites in Xiaolangdi Reservoir were investigated and monitored.The results showed that a total of 19 species of phytoplankton were detected,which belonged to 7 phylums and 14 genera,were monitored.Among them,7 species were Diatoms,accounting for 36.8% of the total number of species.There were 4 species of Cyanobacteria,accounting for 21.00%.There were 4 species of Green Algae,accounting for 21.00%.Gymnophyta,Cryptophyta,Dinoflagellata,and Chrysophyta had 1 species each,accounting for 5.30%,respectively.A total of 9 species of zooplankton were monitored,belonging to 3 phyla and 8 genera,including 3 species of Protozoa,accounting for 33.30% of the total number of species.There were 2 species of Pangaea,accounting for 22.20%.There were 4 species of Arthropoda,accounting for 44.40%.According to Shannon-Wiener diversity index and Margalef richness index,it showed that the comprehensive status of aquatic organisms in Xiaolangdi Reservoir was Class Ⅲ.The evaluation results of water body eutrophic index method indicated that Xiaolangdi Reservoir was in the stage of mild eutrophication.关键词
