Study On Ecological Restoration Technology Of Highway Area In Shaanxi Province

Highway construction inevitably impact on roads through the region’s ecologicalenvironment, mainly for change in topography, disturbed soil, destruction of plant communitystructure and reduce biodiversity, local regional climate effect, increase the risk of soil erosion,etc. If they do not implement protection measures, not only the facility safety and safety ofhighway itself not guaranteed, will adversely affect the surrounding area ecologicalenvironment. Therefore expressway restoration and reconstruction of ecological environment,will become the indispensable important content in the road engineering in the future.Highway construction is the main environmental problems in ecological environmentproblems, with a focus on the expressway of vegetation and soil, and soil field vegetationrecovery and reconstruction. Technical difficulties are a unity of slope protection andvegetation restoration and difficult conditions, and the vegetation restoration andreconstruction of extreme environmental conditions.This article selects in shanbei region, Shenmu~Jiaxian~Mizhi expressway, theguanzhong region, provincial highway in southern shaanxi-Pucheng to Huanglong road andxi ’an to Lantian to Shangzhou expressway as an example, the analysis of the expressway inshaanxi, the guanzhong and highway ecological environment characteristics, the influence ofhighway construction on the expressway ecological environment, puts forward the highwayunder different regional expressway ecological recovery measures and technology strategy.In this paper, the research results can be mainly divided into the following severalaspects:(1) Preliminary divided into districts and shaanxi highway network ecosystem restorationmodel, points area, road type, build the parts suitable for different areas in shaanxi provincehighway construction under the mode of ecological landscape restoration technology,expressway ecological landscape restoration in the region for the future design, construction,management work provides technical basis for the basis.(2) Comparative study on the ecological slope vegetation restoration planting technology, the vegetation planting technology on the expressway regional suitability and applicabilityanalysis section, through the extensive research of typical expressway built plantingtechnology and artificial slope planting simulation experiment research, summed up thedifferent sections of suitable planting technology.(3) Plant ecology based on the typical area of vegetation restoration and the expresswayecological environment engineering practice analysis, select the suitable for different regionsunder the condition of the highway ecological recovery plant species.
