Study On The Road Ecological Capacity And Regionalization

The road ecological capcity is the capacity that the natural ecological environment in the road range may withstand highway construction safely on the understanding that it does not send degenerated. The road ecological capacity regionalization research through the rank division to the national road ecology capacity, to perform the ecology capacity region difference.Highway engineering construction has very deep effect on ecological environment; ecological environment regionalization for highway can help constitute the predictive and measure protection on the course of planning,design and construction etc,and constitute the measure for highway construction in favor of ecological environment protection. In this paper,by the research of the ecological capacity regionalization for highway,it is put forward to the genre system of ecological environment regionalization for highway,and is researched the characteristic and property that several familiar highways impact on ecological environment. It is brought forward aim,methods and principle of the ecological environment regionalization for highway,and is researched the relations among genres factors and indexes.The paper is researched affecting factors of ecological environment for highway, and is established the index system of it,on the basis of index system,it is studied preliminarily division drawing and project,and is made ecological damanding capacity map for highway and ecological supplying capacity for highway by the ARCGIS software,based on the two parameter maps,it is obtained the ecological capacity regionalization map for highway finally.According to the ecological capacity map for highway, researched the project of the ecological capacity regionalization for highway,in the paper country is divided into the five large regions, including ecological capacity earning region,ecological capacity inferior earning region, ecological capacity saturating region , ecological capacity lossing region and ecological capacity seriously lossing region, then it is carved up the secondary affecting region in the large region,the paper is gotten twenty-two affecting region in all,it is evaluated regions at last.
