Research On Harmony Between Expressway And Landscape Along The Route

The expressway is the product of economic development, also is one of national modernization level symbols, with the expressway construction development, on the one hand , the construction promoted the social economy growth, but on the other hand also affected even destroyed the ecological environment and the natural landscape along the route. In recent years, along with the people ecology environmental consciousness's enhancement and esthetic ability's enhancement, as well as walked the sustainable development path's request, the harmony between expressway and landscape along the route brought to people's attention gradually. How to reduce the destruction of expressway construction on the original landscape, and creates harmonious environment; How to enable the expressway construction both meet people's journey needs, and can harmonize with the environment, this is the new problem which expressway construction faced.The paper aims at landscape problem which exists in expressway construction in our country, takes the harmony between expressway and landscape along the route as breakthrough point, the study mainly include four aspects, they are the expressway landscape present situation evaluation along the route, the expressway route selection, the expressway visual impact evaluation and the expressway landscape designs. The conclusions of the study are as follows:(1) Through studying the domestic and foreign landscape assessment method, and unite expressway landscape environment characteristic, has established the expressway landscape evaluation indicator system along the route. It can provide the most basic condition for maintaining harmony between the expressway route selection and the landscape environment along the route, and avoids destroying sensitive landscape.(2) Analyzing the method of route selection in different stage and environmental condition, summarizes the landscape environment problem which in different route selection stage should be pay attention to. The selection of expressway corridor must harmonize with each kind of plan which related along the route, at the same time, in order to reduce the destruction of expressway construction on the landscape environment along the route, must act as circumstances permit in the route design phase, and respect environment fully. Also analysis route design method under the different environmental condition.(3) After analyzing expressway visual environment, the step of expressway visual impact evaluation is put forward, has summarized the method and model of expressway visual impact evaluation. Elaborate the content of visual compatibility appraisal and the visual quality variation appraisal in detail, pays great attention on theory research of expressway visual impact evaluation as foundation, enables it have guide significance in practice.(4) Finally aim at the main problem of expressway landscape design in our country at present, the principle of expressway landscape design is put forward, and point out that expressway own landscape must conformity design with the landscape pattern, the region culture and the landscape characteristic along the route. Through analyzing the design method of different expressway landscape element, has summarized the method of expressway landscape design which harmonize with the landscape along the route.
