系統化法應用於都市土地利用生態經濟發展警度之研究

A Systematized Method Approach to Warning Limit of Eco-Economic of Urban Land Use

「都市土地利用生態經濟發展」是指人類以都市環境、自然資源、人工物資、資金物流與科研技術為基礎，進行土地開發利用，遂行經濟發展，謀求良好生活品質。故土地利用生態經濟發展乃為土地利用與生態資源、經濟發展交互關係之總和，為多重要因不斷交互衝擊與傳導結果的體現，受都市人口增減、土地供需時效、環境資源承載與經濟榮枯之加乘制約，在動力機制、供需機制、環保機制與財政機制交互趨動下，呈現系統性、動態性、模糊性、回饋性、因果性與敏感性。由於都市土地利用生態經濟指標篩選存在著複雜主觀特性，經常悖離變動趨勢及偏離國人實質感受，指標的篩選及警度界限的確定成為都市土地利用研究的關鍵及困難點；本研究藉由多方法協同研究，透過模糊德爾菲專家意見及諮詢，建構都市土地利用生態經濟指標體系，以系統化法配合信號燈系統，以臺中市為個案研究；結果顯示模糊德爾菲可以精簡都市土地利用生態經濟指標體系，彰顯系統化法應用研究兼具質性與量化的優越特質，應用於都市土地利用的警度界限研究確具可行性；建議開展系統化法應用於都市土地利用生態經濟預警機制的協同研究，研擬策略施為，有效控管都市土地利用生態經濟永續平衡發展。

Due to the synergistic effect of urban population increase, land "supply and demand", environmental carrying and economic "growth and decay", the ecological-economic development on urban land use became systematic, dynamic, fuzzy, fed-back, relational and sensitive. By means of collaborative research of multiple methods and Fuzzy Delphi experts' opinions, this research set up a system of ecological-economic index of urban land use. Systemization method and signal light system were employed to make a case study on Taichung City. The findings showed that Fuzzy Delphi simplified the system of ecological-economic index on urban land use. It manifested that systemization method had excellent qualitative and quantitative performance. It was surely workable to apply the systemization method to the research of warning limit on urban land use. It is recommended to use the systemization method on collaborative research of urban land use and ecological-economic early warning mechanism so as to get a strategy to efficiently control the urban land use. Let our ecological economics sustainably develop in balance.
