由於都市化快速發展，促使經濟產生聚集效應與社會網絡連結頻繁，吸引人們往都市集中，因而產生環境超限利用的問題，使得都市維生系統遭受破壞，進而生活品質降低，再加上全球性環境問題(例如：溫室效應、酸雨、沙塵暴…等)的衝擊，已喚起世界各國重視環境保育落實於地方層級發展計劃中。因此，都市在永續發展中扮演著舉足輕重的角色，透過建立生態都市的指標，可作為生態都市永續發展策略的重要參考依據。研究首先自文獻回顧統整生態都市的意涵與指標選取原則，再經資料蒐集後，建立生態都市評估的候選指標，為了增加生態都市規劃策略評估因子的客觀性，運用模糊德爾菲法(FDM)專家問卷篩選評估生態都市發展的指標，並應用層級分析法(AHP)計算指標權重值以增加信度。結果顯示專家學者認為「環境生態」為首要參考依據，之後的順序為「教育文化」、「經濟發展」、「社會安全」及「循環代謝」。再依不同指標所占的權重值進行加權計算，得出生態綜合指數。藉由生態綜合指數檢視及比較台灣數個縣市的生態都市發展潛力，以期作為未來都市永續發展的課題及策略。

Rapid urbanization development often leads economic convergence,frequent social network linkage and attract people towards urban concentration. This may cause overloaded environmental problems,destruction of urban life support systems, and degradation of life quality.Furthermore, the impact of global environmental problems, such as greenhouse effect, acid rain, dust storm, etc., has already stimulated awareness of environmental conservation and to carry out regional development planning. Urban cities, therefore, play an important role in sustainable development. The establishment of the eco-city index is crucial in developing sustainable eco-city strategies.The selection principle of eco-city index is determined initially based on the definition of eco-city found in the literatures. Candidates for eco-city indices are then established. To increase the objectivity of the eco-city planning strategy evaluation factor, the Fuzzy Delphi Method (FDM) is used to sieve through all the potential eco-city indices to esablish the best representative indices. The Analytic Hierarchy Process (AHP) is then used to calculate the weight of the indices to increase its reliability. As a result, experts agree that environmental ecology is the top priority index, followed by education and culture, economic development,society security, and metabolic cycling. The composite eco-indicator is calculated according to the weighing given to different indices. The composite indicator is compared at several potential cities to provide useful guidance and strategies for future sustainable urban development.
