Ecological Revetment Highway Construction In Yunnan

At present the National Highway Construction has shifted its focus from better conditions to the mountain plains, which makes the environmental protection of highway construction in mountainous areas increasingly prominent. However, the highway construction is a modernization project based on the cost of damage to the ecological environment, cutting excavation and embankment filling so on have led to destruction of the original vegetation, animal habitat destruction, soil erosion, such as a series of eco-environmental problems。So restorage and reconstruction of the natural vegetation of the highway and the road sides is imperative.Ecological slope protection at the application of high-grade highway construction is aimed at using the form of a combination of bio-defense and structure protection to govern landslides, and govern earth excavation through the ecological protection caused from substantial soil erosion, restore the vegetation in both sides of the roads, improve road landscape, reduce surrounding environmental impacts caused by highway construction. Now the application of ecological revetment in high-grade highway construction increasingly widespread, which technical development is also quicker. But in the engineering apply in the process have no related design norm and quality acceptance standard, also have no specialized design unit and construction troops. Aiming at the present condition of the theories research after its practiced at engineering in the ecosystem protects, this text first introduce the advantage and limiting of the ecosystem protect usage in the superhighway from the function mechanism and protection function, then introduce 12 kinds of main types and its characteristics in the application of ecosystem protect, elaborate the technique project and vegetation to carry on in the applying of ecosystem protect.For the design project and engineering solid example currently to superhighway ecosystem in Yunnan carry on thorough analysis, and aim at the problems of ecosystem protect application in the superhighway of Yunnan put forward a homologous suggestion.Pass an above contents, clarified the application of ecosystem protect in the superhighway construction at Yunnan. Need according to the ground plateau and geography complicated in Yunnan, characteristics synthesizes to make use of a living creature protection and structure protection technique,Pass the organic combine to make up each limit in managing a slippery ascent. strengthen vegetation sieving and cultivate of different weather area, to adapt to diverse weather in Yunnan, In the meantime start to set up environmental protection consciousness when choose a line stage in the superhighway,orchestrating consider the problems of ecosystem protect application in the superhighway.
