Study On Ecological Restoring Technology Of Mountain Area's Expressway

In recent years, with China's rapid development of economy, the road construction in mountainous areas have flourished, but at the same time the road construction by environmental problems also emerged. How to take effective measures to prevent or reduce road environmental pollution, and restore the ecological environment is a long-term and arduous task which places in the vast road workers.At present, mountain area's expressway construction still remains in the "first construction after green, damage to resume after" stage. Its root is we ignored the ecosystem of road region with the biological characteristics. This article starts from the connotation of ecosystem of road region and analyses composition and characteristics of the ecosystem of road region detailedly. On this basis, focus on discussing the basic ideas of ecological restoration of road region in mountainous areas, and make environmental protection and ecological restoration impenetrate the whole process of mountain area's expressway construction. At the same time, the ecology restoring technology acts as the core of ecological restoration, After investigating the ecology restoring technology taken to the environment of the expressway at present, also uses the foreign outstanding experience and achievements for reference properly, the paper makes overall researches on the restoration of vegetation, land resources restoring technology, wildlife resources protection technology, and sound technologies for environmental protection and water protection technology. Finally, the paper bases on the issue of expressway ecological evaluation indicators and ecological restoration technology which is a son of the western issues "Qinling mountain area's expressway construction ecological protection technology research" to elaborate that ecological restoration apply to expressway construction in practice along the expressway from Hu County to Yang County Shan'xi Province.
