| 摘 要： | 用森林动态模型ＢＫ荭松针阔叶混交林群落在气候变化和ＣＯ２倍增后的反应得出，在气候变化５０ａ后现存的天然红松林林木总株数减少２０％以上，地上部分生物量将减少９０％以上，蒙古栎的生物量占锯林分的５７％以上，林分生产力与现在气候条件下比较接近，略高４％，但主要以蒙古栎、山杨、白桦为主，林分叶面积指数大幅度减少。

| Abstract: | In a simulation model the stand density of mixed coniferous/broad leaved Korean pine forest was modeled to become reduced by more than 20% after 50 years of global climate change (GFDL) and doubled CO 2 concentration. The stand would come to be dominated by Quercus mongolica, Populus davidiana and Betula platyphylla, and its aboveground biomass would be reduced by more than 90%. Quercus mongolica was predicted to come to contribute about 57% of the total stand biomass. The stand productivity was predicted to increase by 4% over no climatic change, though this would be composed mainly of Quercus mongolica, Populus davidiana and Betula platyphylla. The total leaf area index (LAI) of the stand also decreased dramatically under the model. |
