摘要/Abstract

摘要： 在长白山北坡,由于水、热条件及其组合的垂直分异,植被形成了完整的垂直带谱.从表观上看,各植被带间存在明显的过渡带,但由于多种因素的影响,过渡带的位置确定比较困难.文中采用梯度取样方法,应用分形分析、种群分布格局分析和种间竞争分析对海拔1400～2200m的岳桦种群过渡带进行了定量研究.结果表明,岳桦种群在海拔1650m附近与云冷杉林形成一个森林过渡带;在海拔2080m附近与高山苔原形成一个林线过渡带.

Abstract: The vegetation on the northern slope of Changbai Mountains forms a vertical zone due to the vertical differentiation of moisture and heat conditions.Ecotones are obviously existed between different vegetation zones,but it is difficult to decide their positions.In the area from 1 400 m to 2 200 m elevation,we adopted the methods of gradient sampling,fractal analysis,population pattern analysis,and interspecific competition index analysis to describe Betula ermanii population ecotone.The results showed that there was a forest ecotone between Betula ermanii and Picea-Abies forest near elevation 1 650 m,and there was a forest line ecotone between Betula ermanii and alpine tundra near elevation 2 080 m.
