本研究藉由彙整國內生態工程之相關文獻、分別就功能性、生態性、經濟性、環境影響性等層面探討生態工程結構物特性之評估因子，並利用「修正式德爾菲法」設計問卷，建立生態工程應用結構物特性之綜合評估準則。以此表格為基礎，以專家問卷方式求取生態工程結構物之綜合評估指數，並進一步探討綜合指數評估表之可行性。最後再運用「層級分析法」，計算各決策層面及評估準則之權重作為結構物規劃設計時之綜合評估依據。 一、透過綜合指數評估法分析結果顯示，在本研究所列之 15 種結構物中，以打樁編柵之綜合評估分數最高；護岸方面，木排樁護岸排序第一，乾砌石護岸第二，木樁捲包護岸第三。 二、藉由專家之相關性分析顯示，本研究所設計之功能性因子仍不夠周全。但其他層面之評估因子尚屬合理。 三、評估準則之細項因子重要性排序方面，各領域雖有所不同但與整體樣本之權重頗為相似，「安全性」、「適宜性」、「穩定性」、「提供生物棲息環境」、「施工時對環境的破壞」、「結構物完成對環境影響力」此六項因子於各領域中均在前十順位。顯示各領域之專家學者對於此些因子之重視程度具有一定的共識。

This study is consisted of the exploration on the eco-engineering index based on the influence factors such as the function, the ecology, the economy and the environment of the application of eco-engineering. The “Modified Delphi Method” was used to design the questionnaire and establish the integral evaluation principle of ecological engineering method structure. Based on this questionnaire, the integral evaluation index of ecological engineering methods structure was calculated by processionals & scholars investigating and explore the viability of integral evaluation index. Finally, using “Analytic Hierarchy Process” to calculate the weight of counsel and evaluation for the basis of designing the structure. According to the result of integral evaluation index, staking and wattling gives the highest score in the 15 structures; in the revetment, wooden pile revetment is evaluated in first place. Then, rockery revetment is second and stake and infill roll revetment is third place. Based on the correlation coefficients, although the functional index of this study is still not completed yet, the others are applicable. In the priority sequence of important factor in evaluation principles, although each field is different, it is almost the same with all samples. The index including “safety”, “suitability”, “stability”, “offering biological environment”, “the environment damage under construction” and “the environment influence of structure” are the top 10 in each field. That mean all scholars have almost the same common consensus for these index.
