最近全球暖化議題越來越受重視，而都市熱島效應也是構成全球暖化的原因之一。由於近年來遙測影像處理的科技越來越進步，其適合與地理資訊系統進行大尺度環境之綜合分析。因此本研究應用衛星遙測技術配合地理資訊系統，進行都市整體面向溫度的監測分析。本研究應用衛星遙測技術，進行都市整體面向溫度的監測分析，取Landsat 5衛星1995、2009及2011年於臺中上空所拍攝之衛星影像，將熱紅外波段做溫度反演計算獲取地表亮度溫度，進而計算熱島強度，並配合風向、風速及洋流自然因素探討熱島效應之分布情形，以了解臺中地區都市熱島效應現況。此外，根據工業區內分析結果，各工業區內最高熱島強度約在0.6~0.7之間，調查其高溫區域之產業類別結果，包括有：金屬製造業、機械設備製造業、電子、化學、光電產業，玻璃製品業、造紙業、紡織業等，尤以機械設備及金屬相關產業所產生熱島強度最高。

In this study, Landsat-5 satellite images in 1995, 2009 and 2011 were used to calculated the land surface temperature and explore the intensity of the heat island effect. In the results, the intensity is higher in the center of Taichung city and the northwest area. By overlaying with the population map and the industrial map, we found that these areas are the heavy concentration of people and factories. The overdevelopment enhances the urban heat island effect. Considering the different seasons, currents and the wind direction, In the summer, the change of currents and the wind direction make the heat island effect spread to multiple areas. In addition, we explored the heat island intensity in industrial areas. We found that there is no significant correlation between the type of industry and the heat island intensity. The heat island intensity is affected by the wind direction mainly and the higher temperature zone concentrates in the area and leeward.
