Vision Control Method Reserch Of Urban Landscape Design

China is in the process of rapid urbanization. Behind the rapid development in the city, unreasonable construction, random contour lines, results in the destruction of the environment and urban characteristics of urban vision loss.We are getting in touch with the urban environment every time. Quality of the urban environment will directly affect the people. In western country, research on the urban visual landscape is relatively early, and has formed as a system. Meanwhile, some of the cities in China are also achieve some progress in recent years.Due to the research of city landscape visual control in China starts relatively late, the relevant information also less than other countries and regions. What's more, Cities in China mostly under construction, with more uncertain factor. So I will use the following process to talk:To analyzing the stories from London, Chicago and Hong Kong, combing out the overall method of urban landscape visual control.The method mainly focus on the overall visual urban environment and urban landscape environment, included definition, contour line of the whole city, key scenery composition, unit from the perspective of evaluation, route landscape and visual impact prediction analysis, and take Nanjing Youth Olympic Sports Park as an example.The significance of city landscape visual control is that the results applied in practice, protection and utilization of the Urban Vision. Throughout analysis the main method of city landscape visual control, in order to provide a complete visual control method of urban landscape, build more rational urban landscape.
