Abstract: 2008年9月環保署進行淡水河流域水質監測的結果顯示,大漢溪全段及其與 新店溪匯流之後的淡水河上半段之河川水質呈現嚴重污染。污水下水道系統接 管普及率仍低的台北縣臨河市鎮所排放之生活污水為其主要污染源。 本研究計畫之第一年擬建構一涵蓋台北市及毗鄰之台北縣境內重點衛星都 市之台北大都會區區域可計算一般均衡(Computable General Equilibrium, CGE) 模型,並與台北都會區以外其他縣市之區域CGE模型連結,以呈現跨區域間因 產品與服務貿易所形成的產業連結與互動。本研究並擬於台北大都會區之區域 CGE模型中建立一人工濕地部門,呈現目前已開始運轉的3處位於大漢溪右岸的 新海橋人工濕地(一期及二期)及打鳥埤人工濕地,以及台北縣規劃新增人工濕地 之營運及維護成本、單位污水處理成本、人工濕地除污效率的提升,以及其溫 室氣體排放量與吸附量(sequestration)。我們將以此模型評估分析大台北都會區 區域內運轉中及增建之人工濕地,相較於污水下水道系統,在其生活廢污水處 理成本以及廢污水處理系統建造成本上的節約(cost savings)對於大台北都會區 內各區域之各個生產、消費及政府部門、及其他區域經濟之影響,以及人工濕 地對大台北都會區之溫室氣體減量的貢獻。 本研究之第二年擬於大台北都會區區域可計算一般均衡模型中加入工業廢 水處理部門及污水下水道系統部門,比較污水下水道系統及人工濕地之生活廢 污水處理成本,並模擬按差別污水處理成本課徵水污染防制費對於大台北都會 區內各個生產、消費部門以及其區域經濟之影響。同時,我們也將計算台北都 會區內各縣市鄉鎮水污染之質損值(environmental degradation)及各區域之綠色 國民所得(green GDP) , 並評估區域經濟發展對於人工濕地生物多樣性 (biodiversity)之影響。
As the recent EPA monitoring result indicated, the Da-Han River and the upper section of the Dan-Sui River are severely polluted. Main source of pollution is the wastewater discharged from the towns adjacent to the rivers, in which sanitary sewer is not yet accessible. We plan to construct a multi-regional computable general equilibrium (CGE) model for the economies of the satellite cities or towns of the Taipei metropolis, in which inter-region linkage through commodity and service trade is considered. In the Taipei metropolis multi-regional CGE model, we will set up a sector of the constructed wetlands to present the currently operating sites of constructed wetlands in the Taipei County along the Da-Han River for domestic wastewater treatment, and also the planned constructed wetlands elsewhere in the Taipei County. Construction, operation and maintenance costs, unit treatment costs, treatment efficiency and its improvement, and the net emissions of greenhouse gases (CO2 and CH4) will be incorporated to describe the constructed wetlands sector. The model will be used to assess the effect of using the constructed wetlands, as opposed to the sanitary sewer, in the cost-savings for wastewater treatment, and its impact on all sectors within the region, as well as other regions linked through inter-regional trade. In the second year of the project, we plan to add into the multi-region CGE model of the Taipei metropolis the industrial wastewater treatment sector and the sanitary sewer sector. We will compare the costs of wastewater treatment with the three options, and assess with the multi-regional CGE model the economy-wide and inter-regional impact of the differential water pollution levies (on industrial and agricultural sectors, and households). The green GDP, which takes environmental degradation into account, will be calculated together with the results from the model simulations. We will also evaluate the impact of regional economic development on biodiversity in the constructed wetlands.
