Abstract
Urban and rural river dredging is an important measure to improve the ecological environment of rivers,which can remove riverbed sediments,restore the natural flow and ecological functions of rivers.Based on the definition,purpose,and technical methods of river dredging,its positive and potential negative impacts are analyzed on the ecological environment,and the balanced strategy is proposed between river dredging and ecological environment protection.River dredging can improve water quality,restore river ecology,enhance flood control and drainage capabilities,and increase biodiversity.However,river dredging may also damage aquatic habitats,alter the natural shape of rivers,cause soil erosion,and lead to groundwater level and water quality issues.Overall,it is necessary to carry out scientific planning and environmental assessment,apply ecological dredging technology,implement ecological compensation and restoration,and strengthen monitoring and management after dredging.关键词
