Study On The Freeway Landscape Partition Planning

With the rapid development of freeway, the highway constructions have increasingly prominent negative effects on the natural environment and ecological environment; and also threat the sustainable development of society and economy. Therefore, reasonable highway landscape planning has become an important component of the highway construction, besides, further study of landscape planning method is also the realistic need for planning, maintaining and utilizing the natural landscape, cultural landscape and ecological resources, in order to build a harmonious road system which is comprised of people, vehicles, road, resources and environment.Based on the collection of the materials and the analysis of the documents, combined with the actual situation of Shannxi freeway landscape, the thesis analyzes the main problems existing in the construction of the freeway landscape. Through analyzing the visual characteristics of the driver and the law of cognition to the environment, the thesis puts forward the planning idea "freeway landscape partition". Furthermore, using the method of the field survey, network survey, qualitative analysis of the maintenance documents and the weight of the regionalization index done by expert, the thesis determines the sense of beauty differences and the maintenance of the landscape elements, finally, and the thesis determines the results of the partition. According to the partition, the thesis determines the partition attributes. Based on the research results of the abroad and home, combined with the field investigation, the thesis analyzes the landscape design essentials. Taking the XiBao freeway landscape design in Shannxi as an example, the thesis evaluates the landscape resources along the freeway, determines the landscape partition of the Qinling landscape corridor and designs the elements.This thesis could enrich the freeway landscape design experience, protect the natural landscape and cultural landscape along the freeway, promote the process of freeway landscape planning research; besides, the achievements of the study have certain theoretical significance on promoting the sustainable development of our country's freeway and constructing a complete road landscape theory system and technical guidelines.
