| 摘 要： | 利用博州地区4个气象观测站1958--2006年的月平均气温和月降水量等资料，通过气候变化趋势、突变检验、小波变换等分析了近50a博州地区气候变化特征。表明，博州年平均气温处于增暖趋势，90年代前期出现突变；年降水量也呈增多趋势，90年代后期出现突变；气温与降水都具有准4a左右周期振荡：

| Abstract: | According to the data of temperature and precipitation from four representative meteorological stations in Boertala Mongol Autonomous Prefecture from 1958 to 2006, we analyzed the features of climate change by using the methods of trend of climate variability, abrupt change test and wavelet transform. The results indicate that the mean annual temperature in the prefecture shows an increasing trend. An abrupt change of the mean annual temperature occurred in the early 1990s. Annual precipitation is also in an increase trend, and the abrupt change of which happened in late-1990s. The temperature and precipitation have 4-year quasi-periodic oscillations. |
