Spacer characteristics and ramets influence the spatial distribution and resource acquisition of clonal plants. The relationship between the spacer characteristics and branching intensity might have a significant effect on ecological adaptations of clonal plants. The objective of this study was to examine the relationship between spacer characteristics and ramets of Potentilla supina under the different restorative succession periods. The study site was located in Yongchang Beihaizi National Wetland Park, Gansu Province, China. Survey and sampling were carried out in nine plots which were set up along the restorative succession periods of the plots, plotⅠ(5a), plotⅡ(15a), and plotⅢ(25a). Community traits were investigated and 30 clone sequences of P. supina were collected randomly at each plot. Spacer diameter, spacer length, branching intensity of P. supina was measured in the laboratory, and biomass of different organs was measured after being oven-dried at 85℃. The soil physical and chemical properties of three gradients were investigated. The result showed that in the process of restoration and succession of a marsh wetland, the plant height, ortet aboveground biomass, spacer length and diameter displayed increasing trend, while the coverage and branching intensity took on decreasing trend. There were significant negative correlation (P<0.05) between branching intensity and spacer length, and spacer diameter. In the process of restoration and succession on marsh wetlands, in initial stages, P. supina plants use the growth tactics of region resource monopoly, in later stages and endurance, or escape from poor habitat are used. This reflects the unique strategy of survival and reproduction of wetland clonal plants in heterogeneous habitats.
