The Comparison between Ecological Engineering Method and Conventional Engineering Method for the Mountain Area Roadway Design

摘要

This study shows that the traditional engineering method of mountain road construction has not only caused local ecological disturbance directly, but also through each of the stages of the preparation, such as material gathering, construction, continual maintenance, and the diminishing of recycling potential, whereas ecological engineering method, with safety as its main priority, could offer a better ecological condition for construction projects. Through studying the local environmental features and using the proper construction method, the most suitable, corresponding engineering method ought to be adopted. This research uses Analytic Hierarchy Process (AHP) with surveys completed by field experts. This research contains three dimensions: Road Characteristics, Roadside Characteristics, Biological Characteristics. Additionally, actual samples of practical application of ecological engineering would also be discussed to further prove the result and the accuracy of the AHP. Research shows that in the overall planning of a mountain road construction project, ecological engineering method serves to be the better approach.
