Ecological Design In Flood Control Area

In today’s urban construction,revements used solely for flood control design,leading this important ecological and landscape corridor to lose its ecotone function.Concerning the integration of flood control and safety in ecological revetment designing,we should combine hydraulic engineering with ecological landscape architecture.Therefore,based on the research at home and abroad,the purpose of this paper is to establish a set of ecological landscape revetment design method based on flood safety,so that flood hydraulic engineering and ecological landscape design can be organically combined to expand the area of urban green space,water quality will be purified,flood control and storage capacity of river channels will be strengthened,and urban sewage discharge will be planned rationally.First of all,according to the survey of the Dashahe River in Jiaozuo,the traditional hydraulic engineering design method makes the Dashahe river revetment play a weak role in the urban ecology.The significance and feasibility of ecological landscape revetment reconstruction for Flood Control River are discussed based on the characteristics of hydrological region in Jiaozuo and the requirement of 50-year once-in-a-year water level line protection.This article will analyze the ecological revetment based on the following four items:The related concepts and theories of ecological revetment design are analyzed to provide the background for ecological revetment design theory.(2)Through analyzing the research situation of ecological revetment in Flood Control River at home and abroad,the paper provides guidance for the research of ecological revetment.(3)The comprehensive assessment of the ecological revetment of the Dashahe River is carried out through the analytic hierarchy process,and the comprehensive assessment index system of the ecological revetment is established,according to the section of urban ecological water body,three types of rectangular revetment,inclined revetment and compound revetment are taken as examples for comprehensive evaluation,and concluded that the best scheme is compound revetment.(4)The classification and field investigation of the ecological revetment of the city Dashahe River show that the flood control channel can be divided into rectangular revetment,inclined revetment and compound revetment according to the section of water body According to the ecological revetment material can be divided into mixed revetment,natural type revetment,artificial natural revetment.The selection of specific species needs to be designed according to the local river channel type.(5)Through the analysis and study of the Dashahe River in Jiaozuo,the guiding design of flood control ecological revetment can be divided into four aspects:ecological,stable,seasonal and landscape.Finally,it is proved that the ecological revetment reconstruction of Flood Control River course has the function of ecological landscape and Water Conservancy,which is obviously superior to the traditional river course design,the ecological design of Flood Control River course is analyzed and summarized in terms of water quality purification,flood control and storage capacity enhancement,urban sewage disposal,plant arrangement and comprehensive benefit,it can provide reference for other flood control river construction projects.
