| Abstract: |
| Based on the daily series temperature observations from 34 meteorological stations over the period of 1958～2008, the interannual variation, change trend, and change magnitude of the average annual temperature in the Songhua River Basin wer
e analyzed with multi-method of moving average method, non-parametric Mann-Kendall test and the estimated sen slope method. The result showed that the average annual temperature of the Songhua River Basin tended to increase significantly
during 1958～2008. The average annual temperature which underwent abrupt change in 1990 had risen about 2.0℃ during the past 51 years. In four seasons, the average temperature of winter increased at a faster rate (0.06℃/a), whilst the ave
rage temperature of summer had the smallest increment -0.03℃/a. The increasing magnitude of average annual temperature in the Songhua River Basin was much greater than the national and global level. Therefore, effective measures should be
considered to mitigate negative effects of climatic change. |
