Abstract

Key words: Biodiversity, Stability, Plant community, Inner Mongolia steppe

摘要： 自20世纪50年代MacArthur^[1]提出多样性-稳定性理论以来,多样性和稳定性问题一直存在争论。对此Pimm^[2]分析指出,形成多样性-稳定性关系的两种相互对立假说的原因在于多样性、复杂性和稳定性在生态学上有许多不同的定义。事实上,植物群落稳定性的定义和测度方法一直没有统一的认识。Godron稳定性测定方法是法国生态学工作者从工业生产中发现并引入到植物生态学研究中的,它是由植物群落中所有种类的数量和频度进行稳定性计算的方法^[3]。本文利用Godron稳定性测试法计算内蒙古中东部草原6个植物群落的稳定性及物种多样性,探讨物种多样性和稳定性问题,旨在为揭示草原稳定性机制提供新的思路。
