百年來全球大部分地區氣溫變遷的趨勢相當明顯。本文的目的在分析臺灣地區影響年平均溫度、年平均最高溫度、年平均最低溫度及年平均日溫差的自然與人為因素，並找出各因子的重要性及影響力。本研究採積差相關法、複迴歸模型及時間序列迴歸模型分析1961年至2000年的氣溫與潛在影響氣溫因子的資料。分析結果顯示，影響臺灣地區氣溫變化的因素偏重於人為因素，各大都市氣溫變化和產業場所數相關明顯，屬氣候類型相似之大都市的年平均最高溫度及年平均最低溫度的趨勢不同，而且各大都市的氣溫變化和產業類別關係互異；這些結果均顯現出經濟發展可能會影響氣溫的變化。

In the past 100 years, the rates of temperature changes have been obvious in the world. The objective of this study was to analyze the natural and artificial factors that could potentially influence annual mean temperature, annual mean maximum temperature (Tmax), annual mean minimum temperature (Tmin) as well as annual mean diurnal temperature range in Taiwan and to know the importance and the contribution of these factors. The product-moment correlation, the multi-regression model and the time series regression model were used to analyze the temperature data and potential factors affecting temperature changes for the period from 1961 to 2000. The results indicated that the artificial factors influencing the temperature changes were more important than the natural ones. Furthermore, the temperature changes in big cities were significantly correlated to the amount of industries. Finally, the rate of increase or decrease for Tmax and Tmin differed among big cities with similar climate conditions and the correlations between temperature changes and the amount of different industries also differed. Above all, the economic development may affect the temperature changes in urban areas.
