摘要

大型都市所導致之環境問題已被視為對全球性永續發展之最大威脅之一，主因都市地區所產生之大量廢棄物，在釋回生態系時所產生問題之嚴重性已不止於地方性。一都市若要能永續發展，則必須確保其內部與周圍環境資產不會在都市發展過程中被犧牲而遞減。是故都市環境品質之評估必須由整體都會區角度加以衡量。本文即根據此有機性都會區之理念，以自然環境所能提供之維生服務能力，作為評估都會區環境品質之依據。本文並引介生態工程將廢棄物視為副產品，可再回收利用之理念，研擬都會區環境管理方案（污水處理、固態廢棄物管理）；進而透過能值分析，評價生態工程方案對都會區永續發展之助益。研究結果顯示，生態工程視廢棄物為資源，且善用自然界之自我設計能力，將有助於生態經濟系統的生產潛力及環境品質。

Large cities may be seen as a threat to sustainable global development in that they produce huge amounts of waste and pollution which must be absorbed back into the ecosystem, causing problems from local to global in scale. Sustainable urban development will require that environmental capital does not decline overtime, therefore, the evaluation of environmental quality in urban areas must be assessed from the whole metropolitan region. On the basis of organic balance in metropolitan region, this research proposes to use the capability of life-support service provided by the natural environment to urban area as reference for environmental quality. Furthermore, this research incorporates the newly established ”ecological engineering” approach, which regards waste as by-product and should be recycled to ecological system, to initiate scenarios for environmental management if metropolitan region (waste water treatment, solid waste management). The beneficial value of ecological engineering approach to the environmental quality and sustainable development of the metropolitan region is valuated using emergy synthesis. The results indicate that the treatment of waste as resources and the uses of self-design capability of natural environment of the ecological engineering approach can aid in the environmental quality and productive potential of the ecological economic system.
