通过对东大坡木本植物多样性的研究，发现不同海拔梯度的丰富度指数、ＳｈａｎｎｏｎＷｉｅｎｅｒ指数及Ｐｉｅｌｏｕ均匀度指数等均有一定的规律性变化，特别丰富度和多样性指数在某一海拔梯度变化尤为明显． Through the study of the woody plant diversity in Dongdabao, it was found that the abundance index, ShannonWiener index and Pielou evenness index of different altitudinal gradients had some regular changes. The special richness and diversity index were in a certain Changes in altitude gradient is particularly evident.
