| 摘 要： | 物种丰富度作为对生物多样性十分敏感的指数，是总体物种数的偏小估计，所以生物多样性指数是一个偏序集，不宜用林地平均数作为该林分总体多样性指数的抽样估计。在众多的多样性指数集中，Shannon指数为标准多样性指数，具有平均稀有度的性质。将不满足平均稀有度的指数称为边际多样性指数。由实验数据获得长白山系张广才岭14个优势林分多样性指数的抽样估计。根据本质多样性的定义，得到14个优势林分的右尾和曲线值，并作多重比较。结果表明，物种的右尾和曲线的包络线是(0，1)到(S，0)的直线。

| Abstract: | Species richness is a very sensitive index of biological diversity and a partial small estimation of species number.Thereby,the index of biological diversity is a partial set.Sampling estimation of biodiversity index should not use average value of forested land.Shannon index as standard diversity index has the property of average rarity.The index dissatisfying with average rarity is named as marginal diversity index.Sampling estimation of diversity indices in 14 dominant stands were acquired based on exper... |
