| 摘 要： | 利用1964年-2010年气象资料,采用回归分析和滑动t检验等方法,分析中国东北地区典型开垦型农场气温和降水量的变化特征。结果显示：47年来,八五九农场气温在波动中呈显著上升趋势,年均气温线性倾向率为0.14℃/10 a;年降水量也在波动中呈现上升趋势,其线性倾向率为7.51 mm/10 a。滑动t检验结果表明,20世纪70年代末期是八五九农场气温明显由冷向暖转变的分界点;而年降水量在70年代末期由少向多发生较为显著的变化。

| Abstract: | The characteristics and change trend of air temperature and precipitation data observed at a typical reclamation farm in Northeast China during the period from 1964 to 2010 were analyzed by using the methods of trend analysis and moving test. The results showed that the mean annual temperature in this area was in an increase trend in recent 47 years,and the increasing rate was 0. 14℃ per decade,and the annual precipitation was also in an obvious increase trend with 7. 51mm per decade. At the same time,the result of moving T-test showed that the turning point of climate warming of Bawujiu Farm was in the late 1970s. The turning point of climate wetting was also in the late 1970s. |
