摘要:
利用广东省自然保护区陆生脊椎动物名录,分析保护区尺度上物种与高级分类单元在数量上的关系。结果表明,属、科在数量上都随着物种数的增加而增加,且具有相似的增长趋势。物种-属、物种-科在数量上呈现出极显著相关关系( P <0.01, r >0.8),在乘幂模型、线性模型、指数模型和对数模型拟合中,乘幂模型拟合最好。结果显示了,保护区尺度上物种与高级分类单元间具有数量相关规律,且可用模型拟合。因此,在保护区尺度上,高级分类单元的多样性在一定程度上能反应出物种的多样性。
Abstract:
We analyzed the relationship between species and higher taxa (family and genus) based on terrestrial vertebrates species lists by 19 nature reserves in Guangdong Province. The number of genera and families rise as the species list is increased. There are significant correlations between number of species and higher taxa ( r > 0.8, P < 0.01). The power model can best describe the correlations between species and genus or family best than logarithmic model, exponential model and linear model. The results indicated that the significant relationship between number of species and higher taxa existed in the nature reserve scale. Therefore, the abundance of higher taxa may reflect species diversity.
