Research On Landscape Of River Corridor Based On The Perspective Of Landscape Infrastructure

Nature gave birth to the river, the river nurturing the human. From ancient times to the present, People have been lived beside the river, multiplied the next generation, created towns and civilization. Whether in ancient or modern,human life and the development of the city are inseparable from the water, the place back the mountain and faced the water has become the most ideal place for human habitation. Water plays a decisive role in the development of human history. After the industrial revolution, with the continuous expansion of cities, most of the rivers in the city are facing the fate being spillways, sewers, and even landfill. In the initial stage of our country construction, extensive development led to the majority of flows through the industrial city are subjected to varying degrees of pollution,gradually dark, smelly.With the rapid development of cities, urban ecosystem is deteriorating. From the landscape space was compressed to the river water pollution and the river space was in the doldrums, and then to the increasingly unbearable air pollution, which all indicated that the urban ecological environment was fragile. With the rise of ecological city and garden city movement, more and more scholars and experts begin to study and practice, From the"garden city" of Howard to "Landscape Urbanism" of Charles Waldheim, they all made a integration that what role Landscape Architecture can make in the city.Based on this, this paper takes the city river corridor landscape as the research object,using landscape infrastructure as the research perspective, combined with the status quo of city river corridor in Chengdu, utilizing the analysis method of landscape connectivity of landscape ecology theory to research the landscape of Chengdu River corridor,and then putting forward the optimization strategy of Chengdu river corridor landscape based on landscape infrastructure.Firstly, this paper uses the relevant theories of landscape urbanism theory, combined with domestic and foreign river corridor landscape infrastructure related cases. On the macro level, this paper analyzed the connectivity of the river corridor and the ring degree through quantitative study of landscape ecological connectivity from the river of the river network and one or two important corridors in the main scope of Chengdu, Under this basic frame,we can find out the breaking point of river corridor landscape connectivity and put forward the corresponding optimization strategy; Secondly, in the micro level, this paper analyzes river corridor space pattern and vertical space in each section within the Funan River, which combined with the space openness and landscape continuity of landscape infrastructure. And categorizing corridor space according to the different problems, then we can put forward the corresponding optimization strategy according to the different function. This paper took the typical space modes named M1,M2, M3, and put forward optimization strategy for those typical space modes guided by space openness and versatility; Finally, this paper will make some construction suggestions about the main landscape elements inside the river corridor based on the above two aspects analysis of the optimization results.The healthy development of the city landscape along the river corridor has been accompanied by the development of urban construction. The research perspective of incorporating river corridor landscape into landscape infrastructure can provide a new idea and method for the healthy development of urban rivers. The river corridor became the ecological corridor and the green skeleton of the city, which will better guide the development of urban rivers. The research framework of river into landscape infrastructure will open a new window.
