| Summary: | 碩士 === 國立臺灣大學 === 森林環境暨資源學研究所 === 100 === 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.
