Study On Ecological Restoration And Landscape Construction Of Water Environment In Xi'an City

The environment formed by water plays a vital role in the survival of organisms on the whole planet,and at the same time affects the development and life of human beings.Nowadays,with the rapid increase of population and the rapid development of industrial civilization,the surrounding environment of rivers and waters is affected by the rapid expansion of urbanization in modern times.The unreasonable use of water resources causes the shrinkage of the original ecological waters area.Small,rigid revetment and river diversion caused the destruction of the original river water environment ecosystem.The water environment ecosystem of urban rivers has become increasingly prominent.Xi'an has undergone countless changes in the times and contains a lot of historical and cultural traces.Because of its historic and geographical uniqueness,the water environment of Xi'an has high research value.Xi'an,once rich in water resources and with the theory of "Eight Water Around Chang'an",shows its unique water environment.Therefore,the water environment of Xi'an has been systematically studied in this paper.This paper studies the current situation of key water environment in Xi'an,including the Chan River,Ba River,Zaohe River,Weihe River,Fenghe River,Weihe River and Juehe River,and analyses the problems of the formation of their environment.It also classifies and summarizes the problems,analyses and studies several key problems,and achieves a new landscape construction mode by reducing artificial traces and enriching the landscape effect on the basis of safe flood control.The existing water environment control measures are applied to the construction of water environment landscape in Xi'an,and an ecological concept of landscape and restoration is established.The techniques of spray aeration,water aeration,ecological floating island and ecological wetland are artistically treated to make them more integrated with thelandscape around the water area and have more ornamental visual effects.Through the existing research on the ecological restoration of water environment to find suitable ecological restoration methods for the regional water environment of Xi'an City,and take the Weihe River and Juehe River as examples,but also get rid of the original focus on water conservancy and flood control construction,using the combination of landscape and ecological restoration to present a water environment landscape construction model with both ornamental and restoration functions.On the basis of the above research,this paper takes some sections of the Weihe River and the Juehe River as examples to carry out the actual planning,design and renovation scheme,and replaces the previous construction mode of "river + function" by the water environment construction mode of "river + ecological function + landscape".
