生物类群之间物种丰富度的相关性研究是当前物种多样性研究中的热点问题之一,目前,中国尚无相关的研究报道。我们收集了中国三种区域类型:动物地理亚区、行政区和保护区的鸟兽名录,分析了行政区与保护区、动物地理区和经纬度带中鸟兽物种数比值及其相关性。 结果表明:不同区域、动物地理区和经纬度带中鸟兽物种数都显著相关。保护区尺度鸟兽物种 数的相关系数为0.818和动物地理区中的华北区为0.768,其他所有区域和地理区域的鸟兽物 种数的相关系数都高于0.850。因此,鸟兽物种数的相关关系在一定程度上具有预测价值。我们发现不同区域鸟兽物种数比值无显著性差异;但是,不同区域间鸟兽物种数 比值差异显著。该比值在中国呈中间低四周高的分布趋势,其中东北地区最高。我们还利用历史累积调查数据与非历史累积调查数据进行了鸟兽物种数比值及其相关性分析,发现利用累积数据计算的相关性低于非累积数据计算的相关性,但利用累积数据计算的鸟兽物 种数比值高于非累积数据计算的比值。最后,探讨了为什么鸟类与兽类的物种数目会相关。我们根据物种-面积公式,S=CAZ,导出了两个生物类群物种丰富度的相关关 系式。利用全国不同区域数据拟合,得到Z1/Z2=0.913,Z1/Z2接近于1。于是 ,C1/C2可视为近似等于Ram。本研究可推广到其他不同生物类群物种。物种数量的相关关系为快速评估区域的物种多样性提供了一条途径。

In recent years , taxonomic correlation between species richness of different taxonomic groups has been an active issue in biodiversity studies. However , there are cont radictory results. We collected species checklists from three geographic regions : zoogeographic regions , administ rative regions and nature reserves in China. We analyzed both correlation and ratio of avian and mammalian species richness in these regions. We also calculated the correlation and species ratios of bird and mammals in different latitudinal and longitudinal regions. Our result s showed that there were significant correlations ( p < 0.01) between the bird and mammal species richness in each of those regions. All avian and mammalian species richness correlation coefficients were higher than 0. 85 except that of nature reserves , 0. 818 , and that of the North China Region , 0. 768. Therefore , the high correlation between avian and mammalian species richness may have predictive values. There were no significant differences ( p > 0.20) among species ratios of birds and mammals except those of different zoogeographic regions ( p < 0.05) . The bird and mammal species ratio in China was lower in the central region but higher in the border regions with the highest value from northeast China. We also studied the difference in species richness and species ratios calculated with historically accumulated species checklists and modern species checklist . The correlation coefficient calculated with accumulated species checklists was less than that calculated with the modern species checklist , but the bird and mammal species ratio was higher than that calculated with modern data. Finally , we explored why the bird and mammal species richness are correlated. According to the species-area formula , S = CAZ ,we deduced the correlation relationship of these taxonomic groups. When we analyzed all species richness data of bird and mammals , we found Z1/ Z2 = 0. 913 , thus , C1/ C2 approximates Ram . The study can be extended to other taxa. The species richness correlation provides us a means for rapid assessment of species diversity.
