摘　　要：遗传多样性与物种多样性是生物多样性的两个基本层次。近年来的研究表明,环境特征可能对种群遗传多样性与群落物种多样性产生平行效应。本文对遗传多样性与物种多样性关联模型中环境特征对遗传多样性与物种多样性的平行效应部分进行了具体化介绍。基于群落形成的四个基本过程,即突变与物种形成、选择、漂变和扩散,探讨了环境特征对遗传多样性与物种多样性产生平行效应的理论基础。在全球变化的大背景下,研究环境特征对遗传多样性与物种多样性的平行效应及这两个维度多样性对全球变化响应的异同具有重要的生态学与保护生物学意义。然而,目前大多数生物多样性研究仍然只基于物种多样性一个维度,在同一系统中同时对遗传多样性与物种多样性进行整合研究的工作仍然较少。希望通过本文的总结与讨论,能对国内遗传多样性与物种多样性整合研究起到参考与促进作用。Genetic diversity and species diversity are the two basic levels of biodiversity; recent studies have indicated the parallel effects of environment properties on these two levels of biodiversity. Here we introduce the species-genetic diversity correlation model regarding the parallel effects of environment properties on genetic diversity and species diversity. Based on the four basic processes in community ecology and popula- tion genetics （i.e. mutation and speciation, selection, drift, dispersal）, we further discuss the theoretical foun- dations of the parallel effects of environment properties on these two levels of biodiversity. The studies con- ducted on these effects have shown significant importance in ecology and conservation biology, especially in the age of global change; however, few studies consider these two levels of biodiversity together but most consider only one in the biodiversity research so far. Therefore, we review the recent progress and outline the future directions in the study of the parallel effects of environmental properties on genetic diversity and spe- cies diversity. We hope this will benefit and promote the related studies in China.
