摘　　要：为研究气候变化对小兴安岭阔叶红松林的影响,应用生态系统过程模型PnET-II,分别模拟现行气候和未来气候下阔叶红松林净初级生产力(NPP)的变化。结果显示,近43年来阔叶红松林NPP无明显变化趋势。在两种未来气候模拟方案下,阔叶红松林NPP变化趋势都是先增加后减少,但不同的气候模拟方案下,变化幅度略有差异。该成果可为气候变化下阔叶红松林的合理经营提供参考。In order to investigate the effect of climate change on mixed Korean pine and broad-leaf forest, the PnET-II model is used to predict the net primary productivity （NPP） trend of mixed Korean pine and broad-leaf forest under current climate change and future climate change. The results show that the NPP of mixed Korean pine and broad-leaf forest has no obvious tendency during the past 43 years. Under two different scenarios, the NPP of mixed Korean pine and broad-leaf forest, both increase at early stage and then decreases, while the change ranges vary. The conclusions from this study are useful for the effective management of mixed Korean pine and broad-leaf forest under climate change.
