摘    要:基于中国160个测站1951-1997年的月降水和平均气温资料,对不同季节气温和降水的变化趋势及其季节差异进行了分析,并对逐年的变化趋势进行了显著性检验。结果表明,气温和降水的季节性差异很大,增温主要发生在冬,春季,夏季大部分地区以降温为主;秋季降温的强度和范围均小于夏季,增温幅度也小,最后,检验了气温和降水的年变化趋势并与以前的结果进行了对比分析。

关 键 词:气候变化趋势  季节性差异  M-K法  中国  降水资料  气温

Abstract:Based on the data of temperature and precipitation of 160 stations in China from 1951 to 1997, the different seasonal variation trends and their seasonal differences of temperature and precipitation were analyzed, and significance test also was carried out. The results indicate that there is a large seasonal difference of variation trend in China, and that there are warming trend in most areas of China in winter and spring, but cooling trend in summer. In autumn, the intensity and extent of temperature variation is smaller than that in other seasons. Finally, the annual trends of surface temperature and precipitation were analyzed.
Keywords:Climate variation trend  Seasonal difference  M-K method
