| 摘 要： | 根据物种多样性测度公式,对20块样地按乔木层、灌木层、草本层3个层次,分别计算物种多样数指数,结果各类群落的两种物种丰富度均表现出草本层>灌木层>乔木层的特点;多样性指数Simpson和Shannon-wiener在样地中总的趋势均为草本层>灌木层>乔木层;均匀度指数Pielou和Alatalo,在各层间表现出乔木层的均匀度偏低的规律。

| Abstract: | Based on the measure formula of species diversity, species community index concerning 20 pieces of sample land was calculated according to 3 layers including tree layer, herb layer and shrub layer. The results showed that the abundance degree of any two species of a community showed same characteristics, which were herb layer> shrub layer> tree layer; the total tendency of diversity index(Simpson and Shannon-wiener) in the sample land showed the following order:herb layer> shrub layer> tree layer; uniformity index (Pielou and Alatalo) showed lower uniformity law among every layers. |
