Study On The Main Design Elements Of Ecology Landscape Greenbelts For Urban Roads In A Mountainous City

China is a mountainous country in which 2/3 of the land area is a mountainous region. Mountainous town accounts for about half of the national total town. Development of mountain city plays an important role in the overall development of the nation. With the acceleration of city, The Similarly phenomenon in the construction and the disappearance of city characteristics are more serious. As urban road ecological landscape green belt is the basic frame of city landscape, its design, construction level will be directly related to the whole image of the city. It is a direct and effective means to avoid "the similar of city Construction" phenomenon by building ecological green landscape of urban roads.The design theory and method of urban trunk road ecological landscape greenbelt which is relatively rare in domestic and abroad and the design factor is less. But the geological conditions characteristic of the mountain city makes road complexity, therefore putting forward specific design strategy is particularly necessary.This research is written according to the landscape design of Qianzhong Road ecological greenbelt in which the author participated. Through practical experience of the landscape design of Qianzhong Road ecological greenbelt and the Field research of Jinyang Road ecological greenbelt, this research will be discussed on design elements.Through the analysis of related theories at home and abroad and the construction of several ecological greenbelt areas of Guiyang, this research draws three important design elements: the natural elements; the cultural elements and the humanistic elements. The natural elements include terrain elements, plant elements, water elements, soil elements, ecological elements. The cultural elements include the historic cultural landscape, folk cultural landscape, various forms of cultural landscape. The humanistic elements include car crowd visual experience, slow system, landscape service facilities. This research examines their concept, theory, puts forward the design idea and the design strategy, proposes the method of integration among these design elements. Finally this research puts forward the guidelines of the design theory and finally becomes a set of design theory of mountainous city urban road ecological greenbelt.
