中国长白山植物区系的垂直分布格局

为了探讨长白山植物区系的垂直分化特征及其与周边地区植物区系的联系，通过对以往在该地区采集的标本进行分类学鉴定，统计得出长白山共有维管束植物134科517属1 323种。对这些植物从属、种两级进行统计分析，结果表明:长白山4个植被垂直带的植物区系具有明显的垂直分布格局；在整体上具有温带性质，包含有少量的热带成分，主要体现在阔叶红松林带；随海拔的升高，温带性质逐渐减弱，寒带亚寒带逐渐增强。植物区系的垂直变化反映了长白山低海拔植物区系与热带植物区系的联系，以及高海拔地段与北极成分之间的联系。 

Vertical pattern of flora from Changbai Mountain,China
