Curving cutoff is one of the important measures in the regulation of inland waterways.However,while it facilitates the navigation of ships,it also has a certain impact on the aquatic ecological environment of the original river channel and oxbow lake.This article focuses on the ecological impact and restoration issues of the curving cutoff project.By analyzing the quantity of the Pinglu curving cutoff project and combining existing research results,it is proposed that the curving cutoff project will cause damage to the biological habitats in the main river channel and oxbow lake,as well as varying degrees of population reduction.Restoration and mitigation measures for the ecological impact of the curving cutoff project are proposed from three aspects:formulating ecological protection plans,constructing biological habitats,and carrying out construction of river sections for breeding and releasing,the selection and construction methods of biological habitats are analyzed in detail.These measures can provide reference for the green and orderly development of the Pinglu Canal.
