摘　　要：描述了林地边缘不同分层油松林群落的一般特点和物种数量分布,同时计算了油松林物种多样性指标。结果表明,林地内外油松林在物种数量、物种多样性方面均有差异。乔木层和灌木层的物种数量在距离林地边缘5 m时最多,但是,草本层的物种数量从林地内向外呈逐渐下降趋势。乔木层物种多样性指数(H’)在林地内部高于林地外部。灌木层的物种多样性指数(H’)在林地边缘10 m的区域内物种多样性高于其它区域。本研究的结果可为深入了解林地边缘油松林的特点,开发油松林资源提供重要依据。The characteristics and species distribution of Chinese pine were described at the edges of woodland. Moreover, Shannon diversity indices also were computed. The results showed that the distribution were different among Chinese pines. There was the largest number of species in the space 5 m away from woodland edge in tree and shrub layers. However, the number of species in herb layer showed a trend of gradual decline in outside introversion. Diversity index （H＇） of tree species within the woodland was larger than that of outside the woodland. Diversity index （H＇） of shrub species 10 m away from woodland edge was larger than other space. This study can provide an important ba＇sis for understanding the characteristics of Chinese pine and exploiting these resources in forest woodland.
