摘    要:通过对气象因子和样地数据分析表明,20余年来大兴安岭北部气候趋于变暖,低海拔地带蒙古栎呈现明显的进展趋势,演替趋于以蒙古栎为优势种的阔叶林,海拔较高地带蒙古栎更新不良,演替趋于兴安落叶松和几种阔叶树的混生林,蒙古栎种群发展与干暖化具有一致性,在各类气象因子中,5月均低温是影响蒙古栎更新的决定性因子,由海拔升高引起的区域干燥度降低也是影响更新的重要因子,这也说明蒙古栎对冷湿生境的不适应性。

关 键 词:气候变化  大兴安岭北部  蒙古栎  种群动态

Abstract:Northern forests play an important role in sustaining the balance of carbon dioxide(CO_2)in terrestrial ecosystems, the impact of climate change on spatial pattern and process of forest ecosystems, especially in high latitude forest area, has became an important ecological issue in world wide during past decade. With the increased atmospheric carbon dioxide (CO_2)and global climate change, forest stand structure and species composition in north forest ecosystem are effected from stand scale to landscape lev...
Keywords:climate change  Quercus mongolica  population dynamics
