The Protection Research Of Highway Slope Ecological In Northwest

With flying development of the construction of highway, environment along highway has been badly destroyed for a long time. For improve and change this situation, the problem of ecology rebuild for highway has been attached attention on and researched from different ways both in and abroad already. As an important parts of highway, the preventive measures for slope has been paid much attention by highway builders. However, only depended on the tradition preventive measures can not satisfy modern developing ideas, attention to plants landscape has become to the main direction of slope ecological protection.Based on comprehensive analysis of local condition such as climate, topography and physiognomy, natural vegetation, select the greening project of the national highway (GZ45) of Shaanxi part BT24, intimate combine the project of highway and investigate scene, after research the content and theory of slope ecological protection, innovating and developing that in a single step. Do the investigation and analysis on plants selection and grow state, plants combination pattern, the technology of ecological protection and slope landscape design and other aspects. At last summarize some concrete measures that slope ecological protection and landscape building on Bao Tian highway.(1) Selecting local plants with deep and shallow roots to plant, considering the way of slope ecological with recent and future vegetation, multilayer is according with landform condition in northwest.(2) Geogrid and Spray Seeding Technique have better applicability; Geogrid has obvious action on the slope of Bao Tian highway.(3) Linearity landscape and pattern landscape on slope are according with the characteristics of Bao Tian highway,improving the highway space, slope landscape is becoming to the carrier of highway culture.The finally sight of highway slope should conform to local nature and environment's characteristics, landscape design of slope emphasis on selecting plats and disposition pattern, adjust measures to local conditions, landscape manifest region culture feature and create the expressway space with fine environment, realizing harmonious unification between landscape and nature environment. The research hopes to give some important action for the similar areas in the protection of slope ecological and landscape restores of highway.
