摘要: 对河北省围场满族蒙古族自治县木兰围场自然保护区不同海拔分布的油松(Pinus tabulaeformis Carr.)天然次生林群落特征、物种多样性进行研究.结果表明:①在木兰围场自然保护区内共记录到乔木树种1种,灌木树种6种,草本植物种30种;②灌木层和草本层的α多样性指数在一定海拔梯度下所呈现的趋势大致相同,均为比较典型的双峰曲线;③随着海拔差增大,群落间β多样性指数均呈逐渐增大的趋势.
英文摘要: After studying on the community characteristics and diversity of species of Pinus tabulaeformis Carr.at different altitudes in the Mulan paddock nature reserve in manchu Mongolian autonomous county of Hebei procince,we found that:①there is 1specie of arbor recorded in the mulan paddock nature reserve,6species of shrub trees,30species of herbaceous plants;② The changes ofα species diversity of shrub layer and herb layer along with the altitudinal change were mainly the same model,both are relatively typical ...
