The effect of mountainous area expressway on environment and security control based on biological and ecosystem model

摘要

With the social development, change of highway construction concept and the requirement of sustainable development, people put more and more attention on the safety problem of highway driving, and generate more and more demand on visual enjoyment on driving environment. Therefore, the landscape construction of expressway is gradually known by people. However, one the one hand, the design of expressway landscape construction is still in starting stage and lack of systemic method guidance; one the other hand, the large-scale and dynamic expressway landscape construction is bound to affect the weak ecological system of mountainous area and how to take the safety of drive route is still in research. Based on the above background, this paper set up a set of expressway construction method for the mountainous area based on the biological and ecosystem model, including a relative complete environment evaluation, programming, design and theoretical guidance for landscape of expressway. That provides basis for the future relative research and also provides reference for the expressway construction of mountainous area. It is of great guidance meaning and practical significance.
