Analysis And Evaluation The Landscape Pattern Of Changde Urban Road

Roads should reply on the city. China is at its high-tide period of urbanization that the rapid development of urban economics and expanded urban extent both need the relevant road system which produces the contradiction between the environments along the road lines. People have had a deeper requirement on road environment which goes along with the development of economics and creature. People do not focus on the outer beauty any more, but the landscape ecology and the natural, which belongs to the sustainable development. It also satisfies the new demand of the city Changde, after participate into the "3+5" city group. This research is not only in this background, both to the environment and to match the least reduce waste of resources.This article analyses the landscape design on the base of landscape ecology and also uses analytic hierarchy process and fuzzy analysis hierarchy process as a tool which fix on the road landscape. The article also carries out the scientific assessment and provides the references. The conclusions as follows:From the landscape pattern, this article utilized basic principle and the method of the landscape ecology, unified the characteristics of road influence people, select plaques size, number, landscape diversity, landscape dominance index, evenness, patch fractal dimension, landscape polymerization degree index parameters for urban road landscape pattern Changde city were analyzed.Look from the landscape elements, the urban road as people travel channel, plays a main function part ways, bicycle lanes, motor vehicles in urban road landscape of pavement proportion bigger; Look from landscape integral pattern, since the city road is a kind of artificial landscape, a patch points between landscape elements are close, dimension index not complex landscape shape; From horizontal dimension and landscape scale concluded. Each scenic area is large, each landscape diversity in the area of the weighted average patch fractal dimension differ not quite, each landscape areas fragmentation is severe, and the economy relatively developed area of relatively high.The city Changde has a better score in integrative landscape which in accordance with reality. The road design is reasonable which also in accordance with topography that does not exist devastating human behaviors. The road area has 7.6 percent of the hole construction land, while the high sensitivity. The city has relative coordination between traffic and ecological environment, lower pollutant discharge and unfavorable noise pollution.Due to the road environment, the city should reinforce the management and supervision. Second, Changde should reinforce the landscape which combines the arrange function. The city should reinforce the construction of traffic island, traffic bridge and separation strip. The separation strip can fall off the visual fatigue and decrease noise. Besides, the construction should focus on its details, like green diversification and quantification in ecological benefit. Due to the less green space in road, the city could develop the vertical green which expands green space and enrich the green layers. The reasonable arrangement could play a role in developing the quality of landscape ecological system adequately.
