摘　　要：采用相邻格子样方法对种植外来种群落的百山祖主峰一带和周围未种植外来树种植被进行了野外调查,并对群落的物种多样性作了分析比较。结果表明百山祖主峰一带引栽外来树种后,虽增加了木本植物的物种多样性,但抑制了本地乔木树种的生长;在一定程度上改善了恶劣的生境条件,从而增加了灌木层的物种多样性;木本植物的增多,降低了草本植物的物种多样性。The species richness index, species diversity index and community evenness in different plots and layers of the artificial coniferous community in Baishanzu Nature Reserve, Zhejiang Province were analysed by using the adjacent grid method. The result showed that the species richness （19） and species diversity index of woody plants were obviously bigger than those of herbs. Their community evenness had slightly different significance. In the vertical structure of community, the species richness and species diversity index of shrub layer were obviously bigger than those of the tree layer and the herb layer. It was not very different from those between tree layer, shrub layer and herb layer.
