摘要：以泰山南北坡14块样方的调查资料为基础，分析了泰山植物物种多样性沿海拔梯度的分布格局。结果表明：在相同海拔范围内，南坡物种丰富度大于北坡，泰山物种丰富度随海拔的升高而减少。整个群落及不同层次的物种多样性沿海拔梯度在泰山南北坡呈现不同的分布格局。在人为干扰程度低的情况下，北坡的群落物种丰富度在各个层次均较高，而多样性指数在各个层次不一样，北坡乔木层的多样性指数较南坡低，但灌木层和草本层则是北坡明显大于南坡。整体上，物种多样性指数与海拔的相关性，北坡要比南坡好。
The vegetation and plant species diversity patterns along the elevation gradient in Mountain Tai were studied based on the investigation data of 14 sampling plots on the northern and southern slope. The results showed that, the species richness was higher on the southern slope than that on the northern slope at the same elevations. The altitudinal pattern of the species richness decreased with the increasing elevation .The species diversity of community and different layers changed differently on both southern and northern slopes. In the situation of low human disturbance, the community species richness had higher values for the tree layers on the northern slope, while diversity indexes were different for the tree layers, the species diversity of tree layer was greater on the southern slope, but the species diversity of shrub and herb layer was obviously greater on the northern slope. Generally speaking, the correlation between species diversity index and elevationa was better＇on the northern slope than that on the southern slope.
