Landscape Design Of North Urban River Under The Function Of Flood Control And Disaster Reduction

With the rapid development of urbanization,the demand of urban river environment is becoming higher and higher.Urban river plays a more and more important role,not only affects the daily behavior and spiritual life of the surrounding citizens,but also determines the happiness index of people in urban life.Urban river management should be adapted to local conditions,not only consider the flood control and water supply,but also consider the landscape environment to urban development and the impact of surrounding people,which has become the main idea of urban river regulation.Therefore,it is necessary to study the landscape design of urban river under the premise of protecting flood control function.This paper takes the northern city river as the research object,firstly carries on the investigation to the northern city river course through consulting a large number of domestic and foreign urban river channel landscape design theory research and the practice case and summarizes the natural characteristics and related problems of urban watercourses in northern China.And then analyzes and studies the natural situation of river landscape in northern cities.On the premise of satisfying the function of flood control and disaster reduction,it is put forward that the design of urban river landscape is not only to meet the needs of flood control,but also to reform the original simple and simple way of bank treatment.Adopt the method of segmental design and different forms of bank protection to create a variety of functions of the landscape space.According to the local conditions,we should adopt flexible barge handling methods to create a different view of urban river course according to the river.For the northern urban river which has less water quantity and shorter flood period on weekdays,different functions of river channel space are created.It is the first time to put forwardthe division of section area and the ecological restoration method of each section under the function of flood control and disaster reduction of large,medium and small northern rivers.On the premise of satisfying the function of flood control and disaster reduction,it adopts the corresponding design method to different sections,which not only enriches the landscape effect of river,but also broadens the public space of the city.Finally,combining with the landscape design of Yuehe River in Hanyin County,Ankang City,Shaanxi Province,it has carried on the practice application to the above research content.
