| The paper focuses on the landscape ecological problems about highway construction, and put the forward ideas that highway and environmental fusing together. The landscape design key point is neither highway, nor highway landscape, but the "combination" on the highway and along its environment. The landscape design met traffic function, while making highway landscape close to nature and reduce artificial trace, then through various design gimmicks to expressed regional characteristic, then to create feature local landscape.The article is to instruct the highway regional ecological landscape design with landscape ecology and road ecology, and explore suitable ecological landscape planning and design countermeasures for highway regional. This can provide a new approach to the ecological and environmental highway construction. The research is contributes to protect, use, create and perfect the natural landscapes and humanistic landscape of the highway, and minimize the affect of the highway construction, to protect biodiversity and also have important significance in landscaping and sustainable development.By consulting a large number of literatures and practical projects, elaborated domestic and foreign highway development status and science-induced environmental problems. Then summarized the present development about domestic and foreign road landscape in ecological areas. Referenced the research results, then got the highway regional ecological landscape planning theory basis and technical support. Combined the theoretical and practical cases together, then summarized the guiding idea, principle, method and content of regional ecological landscape planning and design. After investigating and researching the natural, ecological and humanistic environment of the Shi-Tian highway, took the landscape ecology, road ecology, landscape ecology theory for guidance, and took roads affected zone as research scope, and combined road with surrounding environment, and made Shi-Tian highway as part of nature, then planned it as a whole within a certain region along the natural and humanistic environment, to divide the whole road into four big biotas: rural biota, farmland biota, mountain biota, and the rivers biota. Based on actual conditions, design these local ecological landscape designs in detail.After research the highway, summarized the regional ecological landscape planning and design methods. Ecological aspects: though recovery destroyed vegetation, rebuilding animals habitat, building ecological corridor which helps animals pass by, restoring farmland, forest, wetland, recovering expressway ecological environment, maintaining ecological balance, restoring original appearance of nature. Landscape aspects: combine natural design type and rural design type together, through the community type of plant configuration mode, widely used local plants, make the road landscape and its surrounding natural landscape has the same style, to get the purpose that the highway landscape combines with its surrounding landscape, constructing harmonious and unified ecological green corridor. Cultural aspects: make full use the rich cultural resources of Han River, through borrowed scenery, getting the scenic spots, native residents into man's view, making people feel rich culture atmosphere. |
