This study was conducted to evaluate the vegetation, distribution and growth pattern of Glehnia littoralis community by the DCA ordination method in eastern coast of Korea. The number of plant species growth with G. littoralis in natural habitat was found 51 taxa, and species of high frequency among 51 taxa was Ixeris repens, Calystegia soldanella, Carex kobomugi, Elymus mollis, Lathyrus japonica and Zoysia macrostachya. Indicator species of Z. macrostachya, Linaria japonica, C. soldanella, I. repens, Carex pumila, Artemisia capillaris, Oenothera biennis, L. japonica and E. mollis in G. littoralis community was differential species of syntaxonomy. C. kobomugi, Z. macrostachya, E. mollis, Cynodon dactylon and L. japonica was the distribution in dryness sand and moisture sandyloam, I. repens, C. soldanella, L. japonica and C. pumila was the distribution in dryness sand. In coastal dune, I. repens, C. soldanella, Salsola komarovi and G. littoralis combined strength of the distribution, and sand of coast was typical of the habitat.
