Study On The Landscape Evaluation Of Firstgeade Highway Upgrading And Rebuilding In The Grassland

At present, People have already been aware that the road not only should has the transportation function, but also the esthetics function of road should be considerfrom many point of view, such as landscape, environment, etc. Road landscape would strongly affect the sight of the user, including the drivers, and directly influence the riding comfort and safety. Inner Mongolia grassland area will face a large number of firstgeade highway upgraded to expressway task in the Eleventh Five-Year. The grasslands area firstgeade highway has its own landscape characteristics, upgrading it will be change the landscape. Therefore, in the context of our country will face a large number of tasks to upgrade the road in prsent and future , we carry out the landscape evaluative of grasslands regional upgrading roads is a very meaningful study.This paper elaborates firstly the concept and characteristics and component of the road landscape with which be the theories foundation of the evaluation of road landscape. Immediately, illustrating difficulties, directions,and supportive theories of establishing road landscape indicator set, with the foundation of the theories of three aspects of landscaping, making sure the environment, function and esthetics of the road are the main contents of the evaluation of road Landscape from visual landscaping,environmental ecological virescence and popular behavioral psychology, and selecting indicator. It carries on filtering the landscape indicators in this foundation, andconstructs indicator set which is suitable for the grassland firstgeade highway upgraded landscape evaluation. Finally, summarizedand analyzed the method of which be used in the evaluation of road landscape,making sure adopting the method of Fuzzy comprehensive evaluation based on the Analytic Hierarchy Process (AHP) to evaluating the road landscape, elaborating the step of that method.The grassland area landscape evaluative research by the numbers in this article,has the instructionsignificance to our country grassland area highway ecology route selection,the landscape construction and the landscape management maintenance. The evaluative indicator set and the evaluative method, which this article proposes, has the model function to other roadlandscape constructions m our country.
