Research On Greening Strategy Of Gansu Province Highways

The highway greening in addition to promote the balanced development of the ecological environment, to achieve coordinated development of land and resources, but also can effectively reduce the occurrence of traffic accidents. Therefore, road greening especially highway greening gradually has get attention, and now also get some achievements. Gansu Province highway greening strategy has been mainly researched in the paper. Firstly, the paper puts forward the significance of this paper, the basic situation of highway greening at home and abroad, and the natural conditions such as soil vegetation in Gansu province were analyzed briefly, the research main content is described. Then the highway greening and recovery of some basic theoretical are analyzed and discussed, highway construction has important significance. For improving the ecological environment in Gansu Province.The ecosystem of the "highway" and "highway ecological restoration system" concept is introduced preliminary, with the highway construction, there will be some ecological problems. In this part some ways to restore the ecological environment also has been put forward. Finally, to strengthen the related concepts and theories of highway greening from many aspects. Secondly, combined with the natural factors of Gansu Province, we try to analysis f the suitable local highway greening plant. The basis of selection mainly includes the local natural environment, the natural geographical factors, the natural plant species, the natural ecological factors, the distribution and selection of the regional plants, and so on. Based on the analysis of ecological environment in Gansu Province, the existing problems of highway greening are put forward according to the distribution of highway greening in Gansu province. Aiming at the problems of highway greening in Gansu Province, this paper puts forward the solutions. At last, the paper summarizes the situation of highway greening in Gansu province and puts forward the prospect of the future.
