森林片断化对植物种群空间遗传结构的影响

Impacts of forest fragmentation on plant spatial genetic structure

空间遗传结构是保护遗传学的重要研究内容,是正确解释植物种群遗传特征,探讨植物适应、物种的形成与进化等因素交互作用,揭示珍稀植物濒危的种群遗传学原因的前提。森林片断化,是全球森林保护中普遍关注的问题,直接影响植物种群空间遗传结构。本文综述了森林片断化对植物空间遗传结构影响的研究进展,介绍了植物种群空间遗传结构的主要研究方法,并对植物空间遗传结构研究方法的局限性进行了讨论。

The role of spatial genetic structure is an important research direction in the field of conservation genetics, and forest fragmentation is one of the important factors that affect the spatial genetic structure of plant populations.. Studies on population spatial structure are helpful to make a correct interpretation of population genetic characteristics, and they are helpful to study the effects of plant adaptation, species formation and evolution. It can reveal the cause of the endangered species. This paper mainly introduces the influence of the spatial genetic structure on the mating system and gene flow of the plant population under forest fragment, and also briefly introduces the research methods of spatial genetic structure. The limitations of the research methods of plant spatial genetic structta-e were discussed.
