Lake Dredging and Rehabilitation
CHEN Youting
Abstract：A systematic analysis of the distribution characteristics and pollution status of lake sediments was investigated,exploring the sources of major pollutants in the sediments and their environmental impacts.Through field sampling,laboratory analysis,and data modeling,the spatial distribution patterns and temporal variation trends of sediment pollution were revealed.Targeted dredging measures and restoration recommendations were proposed to provide a scientific basis and technical guidance for lake management,promoting the sustainable development of the lake's ecological environment.Taking the Donghu Lake dredging project as an example,this study combined theoretical analysis with field research to explore the selection and implementation of dredging technologies.The principles,advantages,disadvantages,and applicable scope of different dredging techniques were analyzed,and the impacts of dredging on the lake ecosystem were assessed.Suggestions for the resource utilization of dredged sediments were also proposed.
