Abstract:	本研究提出以城市「熱點」為基準，並以Stewart和Oke架設的局部氣候區（LCZ）為架構，在城市中小尺度上，深入探索不同城市環境特徵下的熱點分佈模式與規律。主要為氣象研究應用於城市規劃實務提供一項可行的評估方案。本文主要透過臺北盆地地區三期（1990年、2005年及2020年）三十年間的LST與LCZ變化回答以下三個問題：1）區域內30間LCZ與LST之變化特徵如何，是否存在明顯趨勢？2）不同的城市氣候類型區之前是否存在顯著的熱點分佈差異？以及3）都市熱點分佈地區特徵為何，是否存在共通之要素？結果表明臺北盆地地區近30年來經歷了顯著的城市局部氣候區的特徵變遷，並深刻影響著區域內部的極端高溫特徵表現。本研究所採用之分位數法劃分熱點可以為不同數據所產生之圖資提供較為穩定的比較基準，尤其對於非正態分佈之情形比較其它方式對於極端值具有更高的敏感性。 Taiwan, especially Taipei and New Taipei City, are experiencing a significant UHI effect. the two cities are located in a basin surrounded by mountains. Its complex geographical structure makes the impact of UHI significantly more severe than other cities of similar size around the world. This dissertation explored those questions through three periods (the year of 1990, 2005, and 2020) in the Taipei Basin area. The annual changes of LST and LCZ answer the following three questions: 1) The changes of LCZ and LST in the region during 30 years period; 2) What are the characteristics of globalization, and is there a clear trend? And 3) What are the characteristics of the distribution of urban hotspots, and are there any common patterns? The results show that the Taipei Basin region has experienced significant changes in the characteristics of urban local climate zones in the past 30 years, which have profoundly affected the characteristics of extreme high temperature within the region. The quantile method used in this study to identify hotspots can provide a relatively robust comparison benchmark for the map information generated by different data, especially for the case of non-normal distribution, which is more sensitive to extreme values than other methods.
