We compared the species richness of vascular plants in the alpine tundra community of Mt. Changbai in northeastern China and Mt. Tateyama in central Japan. The fine-scale species-area relationships in an area ranging from 0.0625 m2 to 1.25 m2 were investigated, and the number of species per given space and the increas-ing rate of species richness with area were compared between the two mountains. Dominant species were two deciduous shrubs（Vaccinium uliginosum var. alpinum and Rhododendron redowskianum）on Mt. Changbai and two evergreen shrubs（Diapensia lapponica var. obovata and Arcterica nana）on Mt. Tateyama. The coverage and frequencies were greater on Mt. Changbai than on Mt. Tateyama. The number of species per m2 was greater and the increasing rate of species richness was slightly higher on Mt. Tateyama than on Mt. Changbai. We discussed the reasons from the view of dominant deciduous shrubs on Mt. Changbai.
