| 摘 要： | 在福建北部常绿阔叶林内随海拔梯度变化设置面积为1600m2的样地共6个,并应用不同的物种多样性测度方法进行分析,结果表明低高海拔的物种多样性较中海拔低,物种随海拔梯度变化呈现"中间高度膨胀"现象;物种变化速率较大值总是出现在受外界干扰及生境较严峻的低高海拔 同时提出了2个新的指标βz、βh,测度结果表明具有较好的适用性

| Abstract: | Six plots with each area 1 600 m~2 which were analyzed by different species diversity measures were installed in the evergreen broadleaf forest through the change of elevation gradient in the north of Fujian. The results showed that the species diversity of evergreen broadleaf forest in low and high elevation were fewer than those in the middle elevation; species diversity appeared "mid-altitude bulge"; and the highest species turnover rate was always emerged on the low elevation disturbed by people or the high altitude with stern habitat. The two new indices β-z、β-h were put forward, whose results indicated they had good application. |
