博士 / 大葉大學 / 環境工程學系碩士班 / 103 / Taiwan is an isolated island wholly surrounded by sea. The works of coastal protection have always been the great importance to the government and residents behind the dikes. This study is focused on the coastal ecological engineering planning, design and construction process, which give serious considertation to the variety of five major impact factors for discussion and analysis, including afety level, habitat stability, ecological restoration level, landscape level and economic level. Further secondary impact factors are listed, through expert questionnaire, to understand the views of experts and scholars in the field of engineering. The influence strengths, implementation difficulties and the relative influence of each factor weight are covered and analyzed through professional software SPSS and AHP as the coastal ecological engineering decision references.
The study found that the project safety requirement and the challenge in project execution and in aesthetic greening consideration synchronously are in consistency. In addition, the viewpoints of engineering experts on engineering durability and material naturalization implementation are obviously higher than the scholars’. However, in view of landscape level, whether the habitat is strongly interfered by construction, and terraced dike design, the three impact strength factors of the scholars’ are higher than the engineering experts’. Besides, for the consideration of the project cost, the experts tend to reduce the cost through design and management, while the scholars more expect the use and non-use value that the project itself can create.
This study also gets the result based on weight analysis, applying the relevant data on the decision of coastal ecologoical engineering. By adjusting the various factors among one another to prove that the moderate increase of safety level requirement is not entirely a bad thing. It is better for ecological conservation with other moderate factor adjustment.
