摘要
本文介绍了目前产生气候情景的主要方法。给出四种大气环流模式，预测在二氧化碳加倍的条件下松嫩草地季节及年度气温和降水的变化。
In this paper, at first, we intreduce the methods used to generate climate scenarios. The main point is focused on the scenarios predicted by GCMS. Then, scerarios predicted by UKMO'OSU'GISS and GFDL GCMS are intreduced in the bongnen Steppe. The results indicate that due to CO2doubling, winter air temperature may rise 3. 0 to 7. 4℃and winter precipitation may increase 10. 0 ~ 16. 0 %. Summer air temperature may rise 2. 5 ~ 5.5t and precipitation may increase 10 % or so. Annual air temperature may rise 2. 5 ~ 7. 6℃and annual precipitation may increase about 10%. Such changes in temperature and precipitation will have effects on grassland ecosystem.These effects will be looked insight into in future research.
