摘要: | 全球氣候變遷及暖化,各地溫度逐年攀升,同時,都市化所帶來的熱島效應亦使得城市內均溫上升速率大於周遭鄉鎮,為一近年來於都市規劃以及熱汙染領域中相當熱門的議題。本研究透過台灣地區都市化密度最高之台北市區,針對分布於其中之各種綠資源分布及土地利用型態,嘗試透過遙感探測測量工具為基礎,實際探究台北都會區之熱島效應強度,以及不同地表土地利用型對於區域內地表溫度之影響。結果顯示,以空間尺度較大且時間尺度較為完整之遙測衛星熱影像所進行之分析結果相當良好。森林利用地與農業利用地之存在,證實其為都市環境中提供溫降效果之存在,而道路用地之存在則為其中提供溫升效果之存在。綠資源於台北都會區之存在,其面積含量每提高百分之十,提供約0.13℃之降溫效果。針對都市熱島強度部分,於去除海拔效應前台北都會區之都市熱島強度約可達10℃,並以夏季之強度最高,冬季最低。去除海拔效應後,於2007年間台北都會區之平均熱島強度約為3.2℃,與同屬亞洲都會區之香港、北京等城市之狀況相當類似。同時,都市熱島強度以春季最高,秋季最低之結果亦與去除海拔效應前明顯不同。本研究實驗數據資料之統整亦將能提供未來以台北市為範例之都市熱島效應模型建置,並應用於不同都市內,針對都市規劃、土地利用及分配提供建議與效益評估。 Urban Heat Island (UHI) effect is one of the great issues in the modern urban city. Nowadays the temperature rising both in urban and sub-urban areas had been noticed which could become the most serious problem in the oncoming days. Forest and other greenness elements have been widely considered to take great part in temperature reduction. By using remote sensing observation tools, we try out some feasible ways to find out how forest and other greenness affect the land surface temperature. Also, data had been used to find out the urban heat island intensity (UHII) in Taipei city. In result, by using remote sensing observation tools, a much efficient way of finding land surface temperature could be used in this research. Also, mainly both forest lands and agriculture lands could be found out as a significant temperature-reducing element. Roads would be the foremost landcover element of temperature rising. By means of removing elevation effect on land surface temperature, we also find out the UHII during 2007 in Taipei city is around 3.2℃, which is familiar with both Hong Kong and Beijing in Asia. In the final, the result of our research would provide useful information for urban planning for both Taipei city and other urban areas in the future. |
