主要运用气候倾向率和三阶多项式曲线拟合的方法，对珠三角的25个气象站1965—2007年近43年来的年均温和月平均气温观测数据进行了倾向、趋势分析，并对25个气象站气温的空间分布进行统计分析。研究结果表明：珠三角地区气温年际变化的趋势性明显，季节变化表现为夏季和秋季的趋势性变化显著：珠三角地区年平均气温的空间分布可以看到，珠三角的南部地区气温明显高于北部地区，南部和北部的最高和最低温度之差达到2．6℃：珠三角地区的春季、夏季、秋季的温度空间分布的差异不大，冬季气温的南北差异明显，最大温差为2．9℃。

In order to investigate the characteristics of air temperature variation over the Pearl River Delta Region, the annual average temperature and mean monthly temperatures observation data from 25 meteoro- logical stations through 1965-2007 the past 40 years are analyzed by using the methods of climatic trend rate, third-order polynomial curve and 25 meteorological stations of spatial distribution of temperature were statistically analyzed. The results show that the trend of temperature interannual variability is obvious and the trend of the summer and fall change significantly in Pearl River Delta Region. The annual average tem- perature of southern region significantly is higher than that of northern areas, and the difference between maximum temperature of the south and minimum temperature of the north reach 2.6℃ .Temperature differ- ence of the spatial distribution of spring, summer, fall is not significant, and temperature difference of winter between maximum temperature of the south and minimum temperature of the north reach 2.9 ℃.
