缙云山森林生态系统物种多样性空间格局分析

通过对缙云山森林生态系统各发展阶段永久性样地的调查研究，初步揭示森林生态系统发展过程物种多样性空间格局变化规律，发现乔木层物种丰富度和总多样性基本随系统局长的方向逐渐增大，但其过程存在着波动变化，物种均匀变化与系统发展方向关系不大，灌木层和草本层物种多样性变化与群落郁闭度相关。

Spatial pattern analysis of species diversity of forest ecosystem in Jinyun Mountain

On the basis of the suruey on different stages during the development of forest ecosystem in Jinyun Mountain. The results are as follows. The species richness and the total diversity in tree layer increase with the development of the forest ecosystem, but there is some fluctuation in the protess; There is non-dosed relationship between the species evenness and the direction of the development of systems; There exists a correlation between species diversity both in shrub and herb layers schd close ness of community.
