ABSTRACT = {Community succession is an orderly replacement process between dominant species of such community. The mutual opulations changes of two clonal plant species, <i>Leymus chinensis</i> and <i>Kalimeris integrifolia</i>, were analyzed during a process of restoration succession in a degraded meadow in Northeast China. It was based on the methods of space-for-time substitution and continuous sampling in different mixed ratios of community sections. The results showed that the two species populations adjusted the size of ramets to ensure a relatively stable number in the mixed community. The fluctuation and instability were more obvious in the <i>K. integrifolia</i> than in the <i>L. chinensis</i> population. While density/biomass of <i>K. integrifolia</i> showed a linear decrease, there was a concomitant L. chinensis population increase from the middle to the end of the growing periods. The density and taproot biomass of the <i>K. integrifolia</i> population decreased logarithmically with increases in the biomass/cumulative rhizome length of the <i>L. chinensis </i> population during the late and end periods of the growing season. With the progress of succession, <i>K. integrifolia</i> will be eventually replaced by <i>L. chinensis</i>. However, <i>K. integrifolia</i> would be a companion species in the community for a long time.},
