      摘要: 根據松花江流域1961-2000年觀(guān)測氣溫、降水量資料和ECHAM5/MPI-OM模式對該流域21世紀前50 a氣候變化的預估結果,分析了松花江流域1961-2000年年平均氣溫和年降水量變化,并對21世紀前50 a氣溫和降水量變化趨勢進(jìn)行了預估。結果表明,在全球變暖的背景下,作為中國氣候變暖區域響應的先鋒,松花江流域年平均氣溫自1980年代初持續升高,升溫幅度比較顯著(zhù);年降水量在1961-2000年無(wú)明顯增加或減少趨勢,年代際差異也不大。相對于1961-1990年的氣候場(chǎng),21世紀前半葉,年平均氣溫仍將呈明顯增加趨勢,到2040年代升溫幅度達1℃以上,年降水量變化趨勢不顯著(zhù),可能微弱增加,但冬季平均氣溫和冬季降水量都呈增加趨勢,春季降水量也為增加趨勢。

      Abstract: Based on observed temperature and precipitation data from 1961-2000 and climate projection in the first 50 years of the 21st century by ECHAM5/MPI-OM, changes of annual temperature and precipitation in the Songhua River basin were analyzed. The results show that annual temperature has increased dramatically since the beginning of the 1980s under global warming, but annual precipitation had no significant change trends except small decadal variations from 1961 to 2000. Relative to 1961-1990, annual temperature will increase significantly in the first 50 years of the 21st century, with an increment of more than 1℃ before the end of the 2040s; and annual precipitation will show no obvious trends in the first 50 years of the 21st century, but winter precipitation and temperature will increase, and spring precipitation will also increase.

      Key words: Songhua River basin, temperature, precipitation, climate change, projection
