中文摘要	利用中国气象中心160站点的实际观察资料,对中国半个世纪的气温变化进行了系统分析.通过Mann-Kendall趋势分析方法和相关分析法,对各个站点的数据进行处理,对各地的升温响应时间(升温突变时间)同纬度的关系进行了季节对比,发现气温变化趋势和幅度因季节变化存在区域差别:冬季升温范围大,夏季升温成零星状分布;冬季升温更为强烈,夏季升温幅度小,且纬度对各个季节增温幅度的影响也存在着很大的差异:温度越高,升温幅度越大,增温幅度有着非常明显的纬度效应;增温幅度在经度上的季节差异大体上以97°E为界,东西部差异明显.最后针对引起这些升温变化时空差异的可能机制进行了探讨.
英文摘要	The data set of 160 National Meteorological Observatory stations with long-term monthly temperature data in China had been analyzed in this study to discover the seasonal temperature response and the spatial tem-perature structure across China in the past half century.By comparing the distribution of warming up mutation times both in winter and summer,it was found that there are different regional warming-up trends and extents between winter and summer:there are more areas with the greater warming-up extent in winter than in summer;the warming up extent in winter is influenced markedly by the latitude and that of summer is not obviously influ-enced by the latitude;and there is a longitudinal variation of seasonal warming-up extents in the two parts of China divided by about 97°E.At the end,possible mechanisms of the seasonal variations were discussed.
