Study On Ecological Landscape Restoration Design Of Watercourse In Xi ’an

From ancient times to present,life to work and other activities of life in the earth can not be separated from the maintenance of the ecosystem,its composition structure and types are complex and diverse.The largest ecosystem in the world is the biosphere,and the river ecosystem occupies the main part.Over time,the global economy has been rising.The development of society is accompanied by the continuous and excessive extraction and utilization of natural resources,which seriously affects the natural situation of river channels.Since the 20 th century,the living standards of residents have greatly improved,people are no longer satisfied with the simple status quo of food and clothing,they gradually began to yearn for a higher level of spiritual satisfaction.At present,the river is no longer the natural scenery with beautiful scenery in the historical period,and its ecosystem also loses its ability of self-purification and circulation.However,with the rapid development of economy,at the same time,it also promotes people’s deeper learning of knowledge,science and technology,and the higher level of cognition and research related to river ecological landscape restoration.Therefore,how to carry on the river ecological landscape restoration design is our country’s current focus and urgent need to solve the problem.In this paper,the ecological landscape restoration design of waterlogging river in Xi’an is studied.Firstly,the related concepts,theories and design principles are studied.Then,in view of the current situation of Xi’an waterlogging river,field investigation and data collection,found that there are a series of environmental problems.That is,the water quality of river is destroyed,the hydrophilicity of river bank is poor,the artificial trace of bank slope is heavy,soil erosion is easy to occur,and some scenic spots lack unique shining points and so on.The waterlogging river belongs to one of the "eight waters" of Xi’an,and is located in the tourism belt of Guanzhong Ring Line at the same time.Therefore,in view of these current problems,based on various theoretical concepts and literature,from the river ecological security,history and culture,garden art,social and economic aspects,summed up targeted technical methods and measures to repair the river ecosystem and node ecological landscape construction of the two aspects of the overall design strategy research.In the end,the ecological landscape design of the four node areas of waterlogging river Yukou water source protection area,Tianqiao lake,flying college ecological park and Wei waterlogging wetland is carried out while perfecting the river body shape,multi-level purification of water body,ecological river bank and slope sponge city.It is helpful to promote the overall image of waterlogging river and even Xi’an,and make it a green urban space which integrates the functions of safety,ecology,culture,leisure and economy,and has a certain role in promoting the development of tourism industry in the city and even Guanzhong area.At the same time,it is hoped that the research ideas and methods can provide some reference value for the restoration of other river natural environment.
