摘要: 本文就人工林经营中的三种更新方式对植物群落中物种多样性的影响进行研究。结果表明,1200m2样地物种丰富度为:天然更新159种,人促更新130种,人工造林94种;多样性指数(Dsh)分别为4.3004、3.9283、3.5048;多样性均匀度指数(Jsh)分别为0.8484、0.8070、0.7714。人工造林的营林干扰是物种丧失和林分物种多样性下降的主要原因。

Abstract: The influence of three regeneration modes on the species diversity of plant community was studied. The results showed that the order of the species abundance in 1200m2 sample plot with different regeneration modes was natural regeneration (159 species) >artificial promoting regeneration (130 species) >man-made forest (94 species). The diversity indices (Dsh) were 4.3004, 3.9283 and 3.5048, respectively, and the diversity evenness indices (Jsh) were 0.8484, 0.8070 and 0.7714, respectively. The main reason of the species forfeiture and the decrease of species diversity are attributed to the artificial disturbance of plantation forest.

Key words: plant community, regeneration mode, species abundance, species diversity, evenness
