中文摘要	利用中国气象中心160站点的实际观测资料,对中国半个世纪的气温变化进行了分析.通过Mann-Kendall突变分析方法和相关分析法,对各个站点的数据进行处理,发现中国各地在全球升温背景下响应时间以及温度变化幅度的不同步现象及其地理分布规律:各地的升温突变点同纬度变化存在一定的关系,大约33°N左右是中国气温突变时间最晚的地带,以此为界,往高纬度和低纬度方向上都趋于提前;但在四季变化上,通过相关分析发现,从东南往西北存在着敏感性增大的趋势.另外,中国各地多年气温变化同经纬度变化有着密切的关系,在气温变化幅度上,存在从西南向东北增大的趋势.
英文摘要	Global warming or any climate change may cause changes in other geographical elements, including changes in sea level, amount and pattern of precipitation, climate patterns and various other forms of climate change. Such changes can trigger various detrimental effects caused by flood, drought, heat wave, reduction of ag-ricultural yield and in extreme circumstances they can also cause mass extinction. The temperature variation in Chi-na is so complicated that even the temperature trends are completely different in the same period,with temperature increase trend in some areas but with temperature decrease trend in some other areas. So it is very significant to dis-cover the global warming impacts in China and find the regional response laws to global warming. In this paper, a half - century observed temperature data of 160 stations were systematically analyzed using Mann - Kendall method and correlation analysis, and asynchronies in temperature change and their regional distributions were outlined; there is a correlation between the mutations of temperature warming up and the latitude. The area along 33°N is a belt where the temperature mutation occurred latest, and from there to both sides, the mutations began to get earli-er. However, by analysis, there is a trend that the sensibility of temperature changes in the four seasons got stron-ger from the southeastern China to northwestern China; in addition, the rising extents of the temperature got greater from southwestern China to northeastern China. The asynchrony of climate change in China resulted from the conti-nentality caused by the distribution pattern of continent and ocean, as well as the impacts of the Tibetan Plateau.
