We clarified that the grain-size distribution of the surface sediments influenced the vegetation cover and species composition in different sampling areas where sand and gravel were found. We studied wind-beaten bare ground, river beds, and beaches. We analyzed the relationships of vegetation cover, species composition, and life forms with the soil grain-size distribution of the surface sediments and the interstitial particles in gravel. On wind-beaten bare ground, the vegetation cover

On the upper floodplain, more herbaceous vegetation developed where the interstitial soil was finer. On the wind-beaten bare ground and beach, vegetation developed well on coarse gravel, since the larger gravel was relatively stable. The species composition on the windbeaten bare ground and river channels differed significantly depending on the surface sediments. The life forms of plants differed, depending on the grain size of the mineral soil. The species composition also differed with the soil grain size.
