Preliminary Study On The Models Of Ecological Afforestation In Beijing Suburb Highway

Ecological afforestation construction in highway is a important technological means that is a research focus of ecology highway construction in recent yeas. It can alleviate the discord between road system and its surroundings, eliminate the traffic environmental pollution, beautify the highway environment, and enhance the security and comfortableness. Therefore, study on the construction standard and models of ecological afforestation in highway has the important practical significance. The conclusions of this paper can be helpful to coordinate the relation between the highway construction and the ecological environmental protection, and to beautify the highway ecological environment, as well as to enhance economic efficiency.Through systemic investigation of Beijing suburb highways, this article summarizes the existing problems and the main afforestation pattern of highway afforestation. And based on the knowledge of Traffic Engineering, Restoration Ecology, Silviculture, Landscape Science, the research field on the concept and connotation of ecological afforestation construction , and its realization ways as well as the ecology afforestation patterns to be studied thoroughly. By analyzing the relation between highway ecology afforestation and the ecology highway construction, this paper gives a brief generalization of the definition and connotation of highway ecology afforestation. At the same time, it proposes how did the design point indicate species grouping and selection, landscape design, ecological construction and maintenance. Next, the main patterns of central partition belt, outer platform, roadside slope, roadside ditch, the interchange bridge area are generalized and estimated, including the existing problems in Beijing suburbs highway afforestation construction. Finally, according to the quantitative data and the qualitative description, as well as Beijing City Master Plan and suburbs function orientationon , the regions and types of suburb highway are divided, and the corresponding ecology afforestation optimization models and the applied technology are proposed in this article.
