Research On Lake-area Expressway Landscape Design And Its Fuzzy-EAPH Evaluation

With the expressway network developing in our country, the design concept of expressway landscape has also been promoted from functional control design of"economic, strong, durable"to ecological design.However, the design method of lake-area expressway landscape is still not mature, moreover, lack of a perfect evaluation system, which will certainly hinder the construction pace of lake-area expressway landscape.Based on the detailed analysis of lake-area expressway landscape characteristics, this paper has put forward the design target and design principles which are suitable for our country, and has described the research method about lake-area expressway landscape topic style in detail. Then, it has done the element design research on the expressway landscape and given a design example.The slopes in the lake area usually require a higher ability for ecological restoration, for most of which are always in the water. Aiming at this characteristic, this paper has studied the recovery ability of replanting vegetation when designing the slope landscape.The replantation tests mainly contain 3 aspects of typical soil identification, plant combination and anti-erosion simulation. Finally, the plant combination was made an optimal selection in the demands of different soils, different slopes and different slope protections, on the basis of analyzing test results. For the unique characteristics of lake-area expressway landscape evaluation, a more comprehensive evaluation system has been built with 30 evaluation factors, following the index screening principle. Further, this paper has studied the method and the evaluative step about fuzzy-EAHP evaluation on the lake-area expressway landscape evaluation for the first time.The research on lake-area expressway landscape design and its fuzzy-EAHP evaluation in this paper has a guiding significance to lake-area expressway ecology, landscape construction and management maintenance in our country. The built evaluation system and the proposed evaluation method are worth to be learnt.
