| 中文摘要 | 生態工程結構物之設計,除安全的考量外,尚需就生態棲地、景觀美化以及落實生物多樣 性的要求,因此應用材料的選擇以就地取用、天然材料為原則。本研究藉由彙整國內植生木樁 生物性材料之相關文獻、分別就植生木樁選用所需考量評估因子,並以專家問卷方式運用「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,並就 權重計算之結果分別挑選出植生木樁選用時所需考量之「生物性」、「生態性」、「環境功能性」、 「社會經濟性」等四大目標層之重要考量指標,以供現地規劃設計人員之參考依據。本問卷對 象以水土保持相關或景觀生態之專業人士為主,共計寄發兩階段專家問卷,透過專家問卷及層 級分析法分析結果,大綱分項權重分析結果指出,專家學者在植生木樁之選用上,以生物性層 面權重(0.393)遠高於其他三項層面,而生態性(0.278)與環境功能性(0.245)兩層面相去不遠,分 別為二、三順位,社會經濟性層面(0.085)則為最低。 |
| 英文摘要 | Except the safety reasons of the ecological engineering structural designs, it should also consider the ecological habitat, greenery and esthetics to make the biodiversity workable, therefore the used material should consider the local source and nature products. This study was based on the reference papers and selected the influence factors when choose the plant species of live staking, used “Analytic Hierarchy Process” to calculate the weight of counsel and evaluation for the basis of designing the live staking. And then find the sequence of each factor such as the biology, ecology, environmental function and the social economy of live staking. All questionnaires were written by specialists of the soil and water conservation and landscape ecology. The questionnaire was divided into two stages and the result of “Analytic Hierarchy Process” showed the weight ratio (of total effective rate) of biology is 0.393, ecology is 0.278, environment of the function is 0.245 and social economy is 0.085. |
