摘　　要：通过对宝天曼32块样地的4种物种多样性指数进行计算机处理及分析,发现乔木的物种丰富度指数、多样性指数、均匀度指数和PIE的较大值均出现在高海拔和低海拔高度,低值出现在中等海拔高度;灌木的多样性指数较大值出现在中等海拔高度,较小值出现在高海拔和低海拔高度;草本的丰富度指数、多样性指数、均匀度指数和种间相遇率的较大值出现在中等海拔高度.灌木的丰富度指数,多样性指数,均匀度指数,种间相遇率均大于乔木和草本.The four species diversity indices of 32 plots in Baotianman were disposed and analysed by computer. The higher value of species richness indices, diversity indices, evenness indices and PIE of tree occurred at high and low altitude, while the lower value occurred at middle altitude; the higher value of diversity indices of shrub occurred at middle altitude, while the lower value occurred at high and low altitude; the higher value of richness indices, diversity indices, evenness indices and PIE of herb occurred at middle altitude; the richness indices, diversity indices, evenness indices and PIE were higher than that of tree and herb.
