Abstract
Based on the daily air temperature data from 1951 to 2010 and the method of season determination defined by phenology and agricultural production, the characteristics of the beginning, the ending, the duration of every season were analyzed in Nanjing in recent 60 years. The results show that winter has delayed, on the other hand, summer has shifted to an earlier date. Also, the duration of autumn and winter in Nanjing has been cutting down at the speed of 1. 5 and 2. 9 d/10a, but the duration of summer has been lengthening at the speed of 4. 1 d/10a. Mean temperature of spring and winter have risen and mean temperature of summer and autumn have fallen. The relationships between seasonal mean temperature and the beginning date, the duration of the season were analyzed. It has been found that there was a significant positive (negative) correlation between seasonal mean temperature and the beginning date of spring (autumn). The positive (negative) correlation between seasonal mean temperature and the duration of winter( summer) was also revealed.关键词
