摘要
大屯火山群是我國最具地熱電廠開發潛能的區域,前人雖已劃定地熱潛能區分布的範圍,然其係以涵蓋全區地熱徵兆繪製之大尺度圖件,無法直接提供地熱電廠開發選址之用。航遙測技術具有快速且經濟的優點,過去曾運用在臺灣中部變質岩區的地熱潛能區劃分研究,是大區域地熱區快速篩選的利器。本研究進行歷史文獻的地質環境盤點與分析、航遙測的地熱線型判釋以及地熱儲集區評估等方法,完成大屯火山群之線型與儲集區判釋與評估案例。根據本研究結果,大屯火山群地熱區可區分為北投、七星山、馬槽與磺嘴山等4個較具潛勢的儲集區;綜合其地質環境及地熱徵兆類型等特性分析,各儲集區又可再區分幾個小分區,有待後續相關調查資料的整合與驗證,並提供未來地熱開發場址評選參考。

Tatun volcano groups (TVG) is the largest geothermal potential area in Taiwan. There are many studies discussing the potential area in TVG by considering regional scale, while none of them provide site scale selection. This study use remote sensing to identify main geothermal potential areas. Further environment geology study, lineament characteristics identification and geothermal reservoir to identify types of TVG geothermal area. Based on the study result, four main potential geothermal reservoir types are identified which are Beitou, Cising, Matsao and Huangtsuishan, respectively. Integrated the characteristics of environment geology and geothermal potential, every geothermal type of reservoir could divided into sub-potential areas that provided geothermal exploitation site selection reference.
