為追求經濟成長，開發土地必然成為都市發展重要途徑。台灣屬於多山島嶼地理環境，在可供發展土地有限的都市發展決策過程，必須兼顧經濟、社會與環境等健全發展，以保全都市的永續發展。鑑於都市發展政策決定土地資源供給和開發需求的平衡狀態，高階決策群是否具備整體觀容受力思考觀念，成為決定台灣未來能否朝向永續發展的重要關鍵。系統動態學方法論的CLD(Causal Loop Diagram)模式和積量模式，可以聚焦議題與目標，引導整體觀容受力思考，適合做為永續管理都市的決策思考輔助工具。本文以國際著名的都市動態等案例，說明系統動態學方法論的CLD模式和積量模式，如何引導永續管理都市的整體觀容受力思考，顧及經濟成長且聚焦都市整體發展在各項系統容受力之權衡成果。最後，討論整體觀容受力思考在輔助高階決策成為台灣未來管理永續都市關鍵力量之特質與應用價值。 Land development necessarily becomes the key means for economic growth on process of city development. On conditions of Taiwan is a mountainous island and the limited developable land, decisions of city development must considerate the equilibrium within fields of economy, society, and environment for sustainable development, and the mentioned decisions also decide the equilibrium between the supply of land resource and the demand of development. Consequently, the high-level decision group who own the view of holistic thinking with carrying capacity or not, which decides the future of the Taiwan city to become sustainable cities either. Leaning on the national System Dynamics (SD) cases of Urban Dynamics and others, this study makes descriptions of the models of Causal Loops Diagram (CLD) and the Level of SD that are proper assistant methods to help to focus issues, aims, and guiding holistic decision thinking with carrying capacity for sustainable management of the city, which considerate the mentioned equilibrium within the various carrying capacity of diverse sytems on process of the whole city development. This study also talks about the properties and applicational values of the holistic thinking with carrying capacity to be the future power of sustainable managing to assist the high-level decision of the Taiwan city.
