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；再以模擬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，本研究探討臺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，其他層級與權重關係為：第一層級以綠網結構（0.6745）較具重要性，其次是道路區段環境特徵（0.3225）；第二層級以網路連結（0.4660）最為重要，其次是景觀戰略（0.2085）、植物自然構成（0.1787）、干擾效應（0.1467）；第三層級以道路綠帶連續性（0.2167）權值最高，其次是連接綠地面積（0.1348）、道路綠帶寬度（0.1145）等。臺中市西區都市道路生態網路系統應可以綠園道為主，河道為輔向外做一完整性之串聯，並配合道路生態性改善策略，與周邊的綠地有效的連接整合，以形成生態性較佳之綠網結構。

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 network structure (0.6745) and environmental characteristics of road sections (0.3225). The second level category includes four factors, viz. the connectivity of network (0.4660), landscape ecology strategy (0.2085), structure of plant community (0.1787) and disturbance factors (0.1467). The factors fall into the third level of hierarchy system are connected patch area (0.1348), green belt width of road system (0.1145), continuity of road systems (0.2167), etc. In order to improve the landscape ecology of the West District of Taichung City, the ecological network can be developed from the existed greenway system, in conjunction with near-by river corridors to form a more integral green network.
