Abstract：To asist the water environment management of the Baiyangdian River Basin，water samples were collected from the Xiaoyi River and Juma River，two rivers that enter the lake，in April（spring） and July（summer）of 2O2l and 2O22. And the water quality was analyzed and evaluated by canonical correlation analysis.The results indicated that there were diferences in the dominant species of typical rivers.The dominant species of fish in the Xiaoyi River Basin were Rhodeus sinensis，Chanodichthys erythropterus ，Rhodeus ocellatus，Toxabramis swinhonis， Misgurnus anguillicaudatus ， Paramisgurnus dabryanus，Acheilognathus peihoensis，etc. The dominant species of fish in the Juma River Basin were Carassius auratus ， Hemiculter leucisculus， Pseudorasbora parua，Rhodeus sinensis ， Chanodichthys erythropterus， Acheilognathus peihoensis， etc. Water depth，pH，transparency，total nitrogen （TN），permanganate index（ CODMn ），and turbidity（TUR）were the main environmental factors affecting fish communities，with total nitrogen being the most important factor afecting the ecology of the watershed.

Key words： Baiyangdian watershed; fish community；canonical correlation analysis；environmental drivers
