Figure 1 Study area and experiment plots set
Figure 2 Plot-scale hydrological connectivity indices.
Figure 3 PCA and grouping analysis based on the plant traits
Figure 4 Regression analysis between plant traits and hydrological connectivity indices
Figure 5 PCA and grouping analysis based on the spatial structure. T-Number refers to the number of Delaney triangles in each plot, T-Area refers to the mean triangle area in each plot, T-Perimeter refers to mean triangle perimeter in each plot and SCI refers to the structure complex index of each plot.
Figure 6 Regression analysis between spatial structures and hydrological connectivity indices
Figure 7 RDA results of environment variables with plots distribution. Figure 7A gives the relation between plant traits and variables. Figure 7B gives the relation between spatial structures and variables.
Figure 8 Group regression between population density/spatial structure size and hydrological indices based on the biomass.
