摘    要:不同分类类群的物种数目常在空间上表现出显著相关地协同变化,但哪些相关系数之间存在较大的差异?究竟是什么因素导致了这种差异是值得关注的问题。从不同作者的研究方法和数据来源来看,不同研究中的研究方法、研究区域和环境条件本身就存在着差异。除以上影响因子外,我们分析了非环境类因子对物种数目协同变化的影响。结果发现分类类群间的物种数量协同变化差异明显,只有起源和生境要求相似的类群间呈显著性相关;不同鸟兽间的协同变化不存在面积效应,但是空间尺度间的相关性差异明显:物种分布型中东洋型物种的协同变化明显,而广布型和古北型不明显;在鸟类居留型中繁殖鸟与兽类的协同变化极为显著,而其他类型则不显著。综上所述,物种数量协同变化的非环境类影响因子中,生态类型和起源对分类类群间的物种数目协同关系有重要影响,

关 键 词:物种多样性  协同变化  动物地理亚区  保护区

Abstract:There are significant correlations between different taxonomic groups with respect to species richness. However, different studies yield different correlation coefficients between taxonomic groups. In this paper we analysed the impacts of some non-environmental potential factors, such as area effects, taxonomic groups, spatial scale, species distribution, avian residents and travelers on species richness covariance among taxonomic groups, Our results showed that significant covariance only occurred between the taxonomic groups with similar origins and ecologies. There were no area effects in our data set. Spatial scale affected covariance among taxonomic groups, although similar trends only occurred with similar scales. Species with different distribution patterns showed significantly different covariance. There were higher correlations in Oriental species richness than in Paleoartic species richness or between both species. The species richness of avian breeds had very significant covariance with mammals in terms of species richness rather than with other avian ecological types. Therefore, the ecological types and origins of taxonomic groups may have impacts on the covariance of species richness among these taxonomic groups.
Keywords:Species diversity  Taxonomic covariance  Zoogeographic subregion  Natural reserve
