利用森林林隙模式FAREAST，模拟了未来气候变化对东北典型森林类型森林组成和生物量的影响，并根据ECHAM 5-OM和HadCM 3的GCM结果，选择了3种不同的气候变化情景：结果表明，在气候不变的情况下，东北地区森林组成和森林生物量将保持动态平衡，气候变暖对东北地区主要森林类型的适应性不强，主要针叶树种比例下降，沿着随着部分阔叶树种比例的增加，温带阔叶树种/红松混交林带将有上移的趋势，且越暖，越明显;考虑到降雨量的进一步增加，我国东北地区的林带将有北移的趋势，降雨量对温带阔叶树种/红松混交林影响不大。
By using the forest gap model-FAREAST,we simulated the effects of climate changing in future on forest composition and forest biomass of typical forest type in northeast of China.We chose three different climate change scenarios developed from GCMs results of ECHAM5-OM and HadCM3:current climate,warmer climate and the state of changing precipitation with higher temperature.The results show as follows,if the climate goes with no change,northeastern forest composition and forest biomass will maintain dynamic balance.Warmer climate is unadvantaged to major forest type in the northeast of China,The percentage of major conifers decrease,along with the percentage increase of some broadleaf trees.The Mixed broad-leaved tree species/Korean pine forest belt in temperate zone will tend to move up.And more warmer,more distinct.Taken account of rainfall further,the forest belt of northeast of China will tend to move northward,rainfall has a little effect on the Mixed broad-leaved tree species/Korean pine forests in temperate zone.
