中文摘要：

近50年来全球气候变化研究已经是当今自然科学重大课题之一,中国的区域响应也日渐引人关注。依据黑龙江、新疆、西藏三省区93个国家基准或基本气象站1961—2008年间的日气温和降水数据,就中国气候变化敏感区气温和降水变化过程和特征进行对比分析。①气温变化方面,三省区均呈明显升温趋势,研究时段内黑龙江、新疆、西藏增温幅度分别为1.71℃,1.20℃,1.15℃,且都通过了α=0.01的统计检验;②不同季节增温幅度上,黑龙江省以冬春增幅最大,而新疆和西藏则均以秋冬两季增温最强;③降水量变化方面,黑龙江年降水量有所减少,新疆和西藏则有所增多,但趋势都不十分明朗;④黑龙江年降水量的减少主要体现在夏秋两季,特别是夏季;⑤无论年降水总量还是不同季节降水量的年际波动量值均以新疆和黑龙江明显、西藏相对平稳为特征。

英文摘要：

Study on regional response to global climatic changes in China is growing being concerned while the research on global climatic change has been one of major issues in curent natural science over the past forty years.According to daily temperature and precipitation of ninty-three national reference climatological stations or basic synoptic stations from 1961 to 2008,the comparative studies were finished in the variation process and its characteristics of both annual and different seasonal temperature and precipitation among Heilongjiang,Xinjiang and Tibet.The results showed that the mean annual air temperatures of Heilongjiang,Xinjiang and Xizang had increased 1.71℃,1.20℃ and 1.15℃ respectively from the year 1961 to 2008.In seasonal temperature contrast,it is in both winter and spring that the temperature increased fast in Heilongjiang while it is in both autumn and winter that warming is the greatest in Xinjiang and Tibet.In annual precipitation contrast,the precipitation of Heilongjiang Province is becoming gradually less while it has increased in Xinjiang and Tibet,especially more obvious since 1995.To Heilongjiang Province,its annual precipitation has mainly decreased in both summer and autumn,especially in summer.Whether the total annual precipitation or different seasonal precipitations,their fluctuating are characterized by obvious value in Xinjiang and Heilongjiang and relative stability in Tibet.
