Canal development has a significant promoting effect on regional traffic improvement and economic development.However,more and more attention has been paid to the negative environmental impact caused by its large development intensity and complex construction contents.Aiming at the identification of aquatic ecological impact of Pinglu Canal,through the analysis and classification of the construction contents of the inland waterway of Pinglu Canal,combined with the ecological impact analysis of waterway regulation and avionics junction construction,this paper proposes three types of key evaluation contents of aquatic ecological impact of inland river section of Pinglu Canal by analogy analysis and ecological factor identification,and analyzes the impact of construction contents on the main ecological factors.Further more,it sorts out the system of aquatic ecological protection measures from two dimensions of engineering design and ecological restoration.The research results can provide reference for the identification and restoration of the ecological environment influence in the canal development and construction project.
