Research On The Greening Landscape Design Of Urban Viaduct

With the rapid development of the economy and urbanization in recent years,the contradiction of traffic capacity increase continually between the existing traffics and original urban roads.A lot of viaducts start to construct in the city in order to alleviate traffic pressure.The construction of viaducts interflow becomes a scenery line in the city,further improves and enriches the modern city life.But the huge sizes and hard linellae of viaducts affect the urban landscape.It needs green to rich the urban colors and improve the urban ecological environments、the urban ecological benefits、functional efficiency and the landscape characteristics.Therefore,greening landscape of viaducts interflow have attracted much attention.Greening landscape of urban viaducts possess the functions of guilding traffic 、purifying the air in cities and improving the urban landscape.The paper determinately takes greening landscape of urban viaducts as the research object,defines the related concepts of greening landscape design of urban viaducts,and has a research on related discipline theories of development history of greening landscape design of urban viaducts at home and abroad,thus these lay foundations for the paper.Based on the characteristics of viaducts in Hefei,it establishes nine greening landscape of viaducts as the investigation contents,and has the scene investigations and analysises respectively according to the types of the plants 、 the ornamental characteristics of plants 、 the hierarchical structure of the plants and the spatial structure of plants,especially takes Jinzhai road、Tongling road、Changjiang west road,which are representative viaducts in Hefei,as the examples to do the merit and demerit analysis of greening landscape present situations in detail from noumenon、line and node,summing up the practical experiences of greening landscape design of urban viaducts.It classifies urban viaducts in different aspects,expounds the special functions of greening landscape of urban viaducts in the city,analyzes the impact factors and design considerations of greening landscape of urban viaducts.On the basis of the preliminary summary,the paper takes greening landscape design of interflow viaducts of Jixian Road,which is the north-south traffic artery in Hefei,as the example,and put forward the design philosophy and the design mode of greening landscape design of interflow viaducts of Jixian Road.Also,it verifies its feasibility in the design practice.Hope the paper can provide certain theoretical basises for greening landscapedesign of urban viaducts in future.
