Abstract: The approach of space-for-time substitution is used to determine the plant species interconnections in different successional stages of Aneurolepidium chinense grassland in Inner Mongolia. The artificial, degenerated and natural grassland of Aneurotepidium chinense respectively represent the primary stage, mid-stage and climax of the succession process. Plant species interconnections are shown to be the most significant in its primary stage, then the midstage, and the most insignificant in climax stage.The fluctuations of interconnection among some species are also analysed.
