本研究以景觀生態學為理論基礎,利用歸納法相關文獻中篩選出都市道路之生態評估因子,再透過模糊德爾非法、相關性與獨立性檢測進行因子篩選後,確定評估因

子項目;再以模糊層級分析法建立因子權重,建構都市道路系統生態性之評估架構,

用以檢討都市道路之生態性。最後經由實證研究,確立評估架構的完整性,本研究探

討台中市西區都市道路系統之生態功能,並以GIS進行疊圖,最後針對結果做出分析

並建議改善路段與策略。

從本研究篩選得都市道路系統生態功能之評估因子共十二項。都市道路系統生態之評估架構共有三個層級,目標層為都市道路系統生態廊道功能之發揮,其他層級與

Based on the landscape ecology theories, factors affecting the ecology of urban roads were proposed through literatures in this study. The factors were further screened and

confirmed through FDH method, correlation and independency analyses. The weighing of

each factors were subsequently established by FAHP method to form an ecology evaluation

framework for urban road system. The framework was applied empirically on the West

District of Taichung City. Strategies to improve the ecology of ecological network of urban

road inner space were suggested in order that the urban roads can function as ecological

corridors.

Twelve evaluation factors on the ecology of urban road system were proposed which fall into three-level categories of a hierarchy system. The target level is to enable the urban

road systems to function as ecological corridors. The first level category includes green
