The bird diversity index is 1.2399 and evenness index was 0.7271. 该区人工林中鸟类的多样性指数(DI)为1.2399。均匀性指数为0.7271。
Base on the fAFLP data, the genetic similarity coefficient and genetic diversity index among these species were computed. 分析了群体遗传相似系数和遗传多样性指数(DI)以及种间遗传相似系数。
The trend of the change of the diversity index was opposite to that of the variation coefficient. 平均变异系数36.39%,变异系数和多样性指数(DI)的变化趋势相反。
The diversity index was mainly affected by the number of bird species and evenness of population number among species. 群落多样性指数(DI)的高低主要受物种数量和各物种数量均匀度的影响。
The dominant index is in negative correlation to diversity index. Ambient concentrations varied considerably by season. 优势集中性指数与多样性指数(DI)呈负相关变化。环境浓度随季节而大幅度变化。
