摘    要:根据全省86个气象站1960~2007年的温度资料,研究了48年来广东省北部、中部、东南部和西南部4个区域的温度变化特征。结果表明,4个区域的年平均气温均呈上升趋势,最低值分别出现在1976和1984年,最高值为1998年,增温速率南部沿海高于内陆,东南部为0.026℃/年,西南部0.023℃/年,中部0.021℃/年,北部0.012℃/年。各区域年平均气温20世纪60、70和80年代变化不大,90年代升高最明显。从季节分布看,各区域增温速率冬季最为明显,为0.025~0.035℃/年,秋季次之,为0.012—0.031℃/年,冬、秋增温速率均通过了95%的显著性检验;春季为0.011~0.019℃/年,夏季最小,为0.001—0.019℃/年,春、夏增温速率大多没有通过95%的显著性检验。

Abstract:Based on the temperature data of 86 meteorological stations in Guangdong province from 1960 to 2007, the variation characteristics of temperature in north, central, southeast, and southwest Guangdong in recent 48 years were studied. The results show that the annual average temperatures of the above four regions were on rising trends, with the minimum in 1976 and 1984, and the maximum in 1998. The warming rate in the coastland was higher than that in the inland, which was 0. 026 ℃/a in southeast, 0.023 ℃/a in southwest, 0.021 ℃/a in center and 0. 012 ℃/a in north, respectively. The decadal change is little in 1960s, 1970s and 1980s, but significant in 1990s. In terms of seasonal change, for all the four regions, warming rates of 0.025 - 0.035 ℃/a in winter were greatest, followed by 0. 012 - 0.031 ℃/a in autumn, both of which passed the test at 0.05 significance level without exception. Warming rates in spring ranged from 0.01 1℃/a to 0.019 ℃/a, and the least were 0. 001 -0.019 ℃/a in summer , most of which failed to pass the significance test of 0.05 level.
