台灣四周環海對海洋的依存度相當高，然而在經濟發展背後，生態環境不斷遭受破壞，本 硏究針對海岸生態工程從規劃到施工過程中所必須考量的影響因子，這些因子包括安全度、棲 地穩定度、生態復育度、景觀度及經濟度等五項主影響因子，再分別列出每一項主影響因子之 次影響因子，透過問卷調查方式，從領域專家與學者意見中發現，其中具有一致性的包括對工 程的安全要求，以及在工程中兼顧景觀的執行困難度，另外本硏究也發現，專家與學者在包括 工程的耐久性，以及材質自然化的執行上有明顯的差異，此外在工程本身的成本考量上，專家 頃向透過設計與管理降低成本，而學者則比較期待工程本身所營造出來的使用與非使用價値。

Taiwan is surrounded by a body of water, and its dependence on the ocean is relatively high. However, the environment has faced destruction because of economic development. This study focuses on the impact factors of coastal ecological engineering from the planning phase to the construction process. These factors included safety, habitat stability, ecological restoration, landscape degree and the economy. The secondary impact factors for each primary factor were considered. This study obtained the opinions of experts and scholars in the field of coastal ecological engineering through a questionnaire survey. Based on the results, the requirements for project safety and executive difficulty on the landscapes were consistent. However, there were significant differences including the durability of the project and the naturalized materials. From the perspective of cost, experts prefer to reduce costs through design and management, although scholars look forward to the use of non-use values create form project itself.
