Research On Ecological Landscape Renovation Of Riverfront In Tacheng City

In recent years,the rapid development of China’s industry,the continuous expansion of urban population,result in more and more serious impact of industrial pollution and urban land expansion in the city’s riverside space.For example,the intensified pollution of river water,the weakened function of river self-purification,the dramatically reduction of river wetlands area and so on.Therefore,the ecological environment of riverside space became into a vicious cycle,and the river landscape construction also appears convergence phenomenon.At present,the urban riverfront landscape construction,ecological restoration and watercourse regulation are carried out simultaneously,usually from the aspects of ecological,landscape,water conservancy,humanities to manage comprehensively.The study of the ecological landscape of riverside is based on the principle of improving the ecological environment of the riverside.Under the condition of satisfying the basic functions of the watercourse,the goal of harmonious development between man and nature should be achieved.The transformation of the riverside ecological landscape should get the goal of "people-oriented and environment-oriented".This paper mainly from the views of both the unity of opposites,ecological environment restoration and landscape design,seek a method to both the ecological environment and landscape construction taken into account.Based on the relevant literatures on the ecological transformation of riverside and the protection of urban rivers and wetlands,this paper summarizes the relevant concepts,principles,composition and classification of urban riverfront spatial planning at home and abroad.On the basis of relevant domestic and foreign related literatures on the transformation of ecological rivers and urban wetland landscapes at home and abroad,the method of urban riverfront spatial planning method is studied.Taking the riverside planning of Tacheng in Xinjiang as an example,the paper analyzes the urban river in the city of Jiawuertamu river and Chengdong river.In combination with Urban natural and cultural conditions and the status of urban construction,develop research program of ecological transformation of Tacheng urban river and river wetland,to provide operational guidance of improving the ecological environment of Tacheng.The main results of this paper include the following aspects:(1)Through the study of the theory and method of urban riverside space reform,in combination with the relevant literature,drawing on the successful experience at home and abroad,clarify the planning principles of urban riverside space.And around the different functions,grades,conditions of the river,Pattern,ecological restoration,plant configuration,node design and other key factors in the riverside space,the paper puts forward the theoretical method for the landscape design of different types of rivers.(2)Through on-the-spot investigation,on the basis of multi-angle analysis of the status quo of the Jiawuertamu River and Chengdong River,the status quo questions are classified and described,such as river hardening and simplification of the contradiction with the biological diversity,human behavior on the river pollution,channel status quo and modern urban construction conflict,urban river wetlands without planning management and protection measures hazards and so on.(3)Through the study of the reconstruction of the Jiawuertamu River and Chengdong River,improve the ecological environment of the river and restore the ecological environment of the rivers and riverside,so that the water environment and ecosystem achieve a virtuous circle until the riverside space update and human quality of life needs,and enhance the sustainable development of the city to achieve a balance between mankind and nature more harmonious blend.
