| "Eco-highway" is an advanced construction concept is the future direction of developme nt road, co-existence mainly people, nature, when construction will reduce the human factor to a minimum damage to nature, to highway construction and ecological environment coordi nation purposes。But for now, China’s late start of the study of ecology road,Ganzi Tibetan Autonomous P refecture in Sichuan Province as a national key ecological function areas, they belong behind the poor western regions, mainly for road construction Bao Tong, Paul Chang-based。Therefore, for the construction of a more ecological highway behind more developed inla nd regions.In recent years, Ganzi proposed’ecological state "development strategy, the curre nt necessary to develop the economy, but also to protect the ecological, can no longer take th e old road after the first destruction of governance,Based on the combination of Ganzi Ganzi ecological environment and culture, based on the analysis of geographical features, the impo rtance and significance of mountain ecosystems Ganzi road construction.Highway is an artificial ecosystem, its impact on the ecological environment along the m ulti-level, multi-faceted,Therefore, the construction of ecological highways need to be addres sed are multi-faceted, multi-level,For example:line selection, roadside vegetation restoration , soil conservation, prevention, road transport of dangerous goods risk prevention, wildlife co nservation issues such as road noise,This paper focuses on two of the content, the ecological line selection, revegetation.First Ganzi to develop economic and social, ecological road const ruction is a very long period after Ganzi unavoidable choice,Full field of tourism as the core of economic development, but with 318,317 national highway as the support, not enough to a chieve the goal of global tourism, passage between the county and the county needs to get thr ough,Therefore eco line selection can not be ignored, should take full account topography, as much as possible to avoid the nature reserve, environmentally sensitive areas of drinking wa ter source protection areas, scenic spots and so on, in environmentally sensitive areas will ine vitably need time through, we must strictly implement the State concerned laws, environmen tal protection and reasonable conduct comparison and engineering comparison, has determin ed the correct alignments.Kowloon county road to asbestos as an engineering example, route selection process adhere to building a resource-saving and environment-friendly road as the basic concept of the project through farmland, basic farmland, woodland area of selection, an d a line through natural analysis of the impact of protected areas, a reasonable choice of align ments nine stone road, correctly handle the relationship between transport development and e nvironmental protection.Second, the technical content of complex ecological restoration, ma ny, but vegetation restoration technology is an important part of any ecological road construc tion plains, mountains and other regions and central part, need to take green design, to avoid road area within the range of vegetation restoration incompatible with the surrounding enviro nment, according to different backgrounds native plants, build new tree, shrub and grass mul ti-level plant community, the goal is to foster plant community succession roadsidedeforestry focus now,"Natural harmony" is one of the important goals of vegetation recovery.Research on the roadside vegetation restoration techniques, presented the best plant design, planting, c ustody technologies to solve transportation construction projects mountain vegetation restora tion problems in order to create favorable environmental conditions, protect the seedlings thr ive.And State Road 318 line segments vegetation Kangding to xinduqiao restoration project, for example, by fully investigating the ecological environment ecological and environmental conditions of climate, soil, vegetation, wildlife and other resources Kangding area, research t he best programs in the road vegetation recovery. |
