A, Point pattern analysis of L. chinensis population in each replicate (A1, A2 and A3 refer to replicates 1, 2 and 3, respectively). B, Point pattern analysis of L. chinensis population integrating data of three replicates.

A, Point pattern analysis of S. grandis population in each replicate (A1, A2 and A3 refer to replicates 1, 2 and 3, respectively). B, Point pattern analysis of S. grandis population integrating data of three replicates.
Fig. 4 Spatial association between Leymus chinensis and Stipa grandis populations in communities with eight years of restoration. -●-, observational data; --, the 95% confidence limits resulting from fixed S. grandis population and random L. chinensis population. A, Spatial association between L. chinensis and S. grandis populations in each replicate (A1, A2 and A3 refer to replicates 1, 2 and 3, respectively). B, Spatial association between L. chinensis and S. grandis populations integrating data of three replicates.
