| 摘 要： | 基于1956—2005年中国逐日最高气温的气象站点数据，采用Mann—Kendall法、滑动t检验和Yamamoto法三种方法对其进行突变检验，结果发现：全国8大自然地理区的年和四季平均最高气温的突变基本上发生在20世纪90年代．在区域上，表现出北早南晚的空间差异；在四季中，冬季发生突变的时间最早，秋季各地发生突变均不明显，春夏两季和年平均最高气温发生突变较晚且时间类似．通过与日平均气温的突变时间比较发现，平均最高气温突变的出现时间均晚于日平均气温的突变．

| Abstract: | Based on the meteorological station data of daily maximum temperature from 1956 to 2005 in China, the abrupt change of the mean maximum temperature was analyzed using the Mann - Kendall method, the moving t - test and the Yamamoto method. The results showed that the abrupt change of the annual and seasonal mean maximum temperature of the 8 natural geographic regions in China mainly appeared in the 1990s. The changes showed a significant spatial difference that the northern area occurred earlier than the southern area in the warp - wise of a region. The abrupt change of the winter is earliest in the four seasons, the abrupt change of the autumn was not obvious and the change in spring and summer was similar and appeared later. Compared to the abrupt change of the daily mean temperature, the abrupt change of the mean maximum temperature happened later. |
