Abstract: In order to investigate the community composition and distribution of Cladocera and Copepoda and to study the related influences of water environment, Cladocera and Copepoda and the factors of water environment in Baiyangdian were investigated in August 2018. Based on the technology of DNA barcoding, the species of Cladocera and Copepoda were identified, and the phylogenetic trees were built and their genetic distance were established. And 3 families 5 genera 8 species of Cladocera and 4 families 9 genera 14 species of Copepoda were investigated.Canonical correlation analysis(CCA)was used to analyze the relationship of Cladocera and Copepoda and water environment. The results showed that Zn content was the main factor for the difference of the regional distributions between Cladocera and Copepoda. The number and community composition of Cladocera species were negatively correlated with P content. The growth of each species was affected by different environmental factors, and the same environmental factor also had different effects on the distributions of different species.
