Study On Optimal Selection Of Mountainous Tourism Highway Alignment Plans

Route selection of mountainous tourism highway should be harmonious with the surrounding landscape environment and ecological highway system of landscape should be established. Scientificity and reasonability of route plan direction is the key to whether the construction project can reach the expected effect. At present, in engineering practice, traditional route selection only considers technology and economic factors, and often neglects landscape ecological environment. In this way, the landscape ecological environment will be destroyed. Therefore, it is quite necessary to set up a comprehensive route evaluation model.By relying on mountainous tourism highway engineering of Damingshan Mountain in Guangxi, directing at optimal selection of mountainous tourism highway route plans, and combining with characteristics of the tourism protection zone in Damingshan Mountain, this topic proposes route selection principle, basis and influence factors of mountainous tourism highway. Besides, it analyzes evaluation indexes in safety, landscape ecological environment, technology, economy and social environment of highway alignment plans in Damingshan Mountain Tourist Area. Meanwhile, the evaluation index system is established. Discussion is made for optimal selection of route plans by considering the influence of ecological environment factor and neglecting its influence via analytic hierarchy process. Moreover, weight of criterion layer and index layer in the evaluation system is determined according to AHP. At the same time, by combining with FCE method, comprehensive evaluation model is set up. In addition, fuzzy comprehensive evaluation is conducted for alternative plans of mountainous tourism highway in Damingshan Mountain. An optimal selection is made among the alternative plans, so as to gain a relatively reasonable and reliable result. According to the evaluation result, this model is very practical.
