Changes of the distribution of plant communities and species diversity on the gradient of the water table in the delta of the Nakdong-river were studied by means of the method of Curtis and Patten, and the index of Shannon and Wiever. The communities were arranged in a single dimensioned ordination on the basis of the importance values of the persistent species. Leading dominant species from the low, level to the high level of the water table gradient, were Phragmites longivalvis, Cyperus flaridus, Ischaemum anthephoroides var. eriostachyum, Imperata cylindrica var. Koenigii, and Oenothera Lamarckiana. These species form a continuum depending upon available soil moistrue. Species diversity, oragnic constituents, standing crops, available P and exchangeable Na contents of soils showed a good relationship with gradients of the water table.
