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发展的方向逐渐增大，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． Through the investigation and study of the permanent plots at different development stages of forest ecosystem in Jinyun Mountain, the spatial variation of species diversity in forest ecosystem development was initially revealed. It was found that the species richness and total diversity of arbor layer gradually increased with the development of the system, but the process fluctuated. The uniform change of species had little relation with the direction of system development. The species diversity of shrub layer and herb layer correlated with canopy density.
