%X Statistical analyses over time suggest that Leymus chinensis rhizone lengths and branching angles are independent of each other, and also of the previous branching angles and rhizome lengths. This paper shows that the process of clonal growth in Leymus chinensis is consistent with stochastic simulation models and random-walk models. This study represents the application of random-walk models to pattern of the vegetative spread of clonal plant Leymus chinensis.There was no statistical difference between observed ramet displace- ments and displacements predicted in a correlated random-walk and diffusion models. These models can be used to make quantitative predictions about the spread of Leymus chinensis population.
