The use of these elements, however, creates a monotonic appearance and the quality also cannot be well controlled. Moreover, because of these elements do not support vegetation, they can cause significant impacts to the local habitat of plants and animals. Environmental changes can bring substantial damage to the environment, and people have become more aware of the importance of ecological conservation and environmental protection. The term "ecological engineering" was first proposed by Odum in 1962, and the concept was soon introduced into Taiwan, prompting the government of Taiwan to actively promoting the ecological engineering methods. This ecological conservation and safety oriented new engineering approach not only reduces the occurrence of landslides along mountain roads but also creates a more appealing look as well as matches natural environmental changes. This study, focused on mountain roads, assessed mountain roadside slope construction and ecological effects. The effect of applying ecological engineering methods on roadside slope construction was explored, too. This research first discussed differences between the conventional slope protection and the reinforced slope protection, and then factors related to their failure were analyzed. The basic structural components of these two types were compared as well. Lastly, a questionnaire survey was conducted, and the obtained information was used as the benchmark in the discussion. The analytic hierarchy process (AHP) was adopted to obtain the weight of each assessment factor, and the result were analyzed. The findings suggest that biological characteristics and life cycles were much more weighted than all other aspects, whereas road design and economic cost were weighted much less. Therefore, scholars have recognized that biological characteristics and life cycles are the most important issues. Global warming has an effect on climate change, and countries worldwide have begun to pay attention to this issue by integrating ecological conservation into their public infrastructure. Both public infrastructure and ecological environment have to be taken care of as equally important. As a result, ecological system stability and environmental pluralism need to be incorporated into public infrastructure. For the construction of mountain roadside slope protection, it is critical to take care of every detail to prevent causing environmental impacts. Using resources effectively can also maximize the effects. While using roadside slope protection to secure the earth, it is also important to add planting to beautify the environment and minimize greenhouse gas impacts. Through summarizing relating factors and reviewing relevant studies, the author hopes to generate positive information on mountain roadside slope construction and ecological effects and furthermore, to disseminate the idea of sustainable development.
