Research On Vegetative Colorful Landscaping Along Two Wings Of Freeway In Deyang

Landscape along the highway is a kind of dynamic four-dimensional landscape for occupants to view. The study involved Landscape along the highway should meet the security requirements and aesthetic needs of humanized landscape.This study set mountain landscaping along the section from K45+745 to K57+700 of Cheng-Mian highway as a design case. On the basis of summarizing the existing research, use the relevant information and data of the project road topography, green status and weather, water conditions which are get before design by field research, do original visual sensitivity assessment of landscape. According to level of visual sensitivity results from four assessments,which are the video, distance of the sight, the relative slope,and striking degree of the landscaping, combine application rules of colors along the highway landscape, form a total of 13 species of plant landscape mode for using along the highway to guide the construction of the plant, and form different characteristics landscape.(1)During the design process of mountain landscape along the highway, we could refer to the following influence factors which was get before design by summary and analysis:environmental characteristics of landscape along the highway, color characteristics of the landscape, biological & visual characteristics of the landscape plants, dynamic visual & psychology characteristics of occupants.(2)According to research results and the relevant planning information of Deyang, consider the topography, original vegetation and project funding of study area, figure out the main design area of design scope preliminary, totally thirty blocks. The average distance between them is 200m. This provides reference for similar landscaping.(3)In this article, we did pre-design assessment of landscape through visual sensitivity analysis. It develops four evaluation criterions:video, sight distance, relative slope and striking degree of landscape and get visual sensitivity comprehensive assessment score of different design block. The design blocks are divided into high, medium and low levels of visual environmentally sensitive areas, among them, there are 17 belongs to high sensitive areas,15 medium sensitive areas and 6 sensitive areas.(4)The landscape design of the colourful forest established five distinct scenic spots: Da Tong Wen Ying","An Xiang Xi Yuan","Sheng Yang Fu Cui","Chun Hua Chen Xi" and"Cu Jing Tian Gong"; five colorful themes were clearfresh, fragrant, ecological,new and prosperous, respectively; from the color, shape, attitude, taste, sound and other aspects, the colourful landscape with both ornamental value and local characteristics was outlined.(5)Five land types, five color themes and three landscape sensitive areas formed thirteen types of plant landscape configuration modes of the landscape applicatiom,which were:six for the highly sensitive areas, five for the moderately sensitive areas and two for low sensitive areas.
