We had been measured the germination of seedling, biomass, growth of root and shoot, the length of taproot and lateral root, and the change of area from 2004 to 2006, in order to examine the dynamics of halophytes communities in the salt marsh of Ham-pyung Bay. In Ham-pyung Bay, Suaeda maritina, Phragmites communis, and Zoysia sinica were composed of dominant community. Biomass of those species dramatically is increased in recent 3 years. Comparing other species, the length of taproot and lateral root of Suaeda asparagoides was fast increased after August. The taproot growth of both Suaeda asparagoides and Suaeda maritina was continued at the same rate, but only Suaeda asparagoides dramatically increased since August 2005. The growth of lateral root of Sueada maritima and Sueada herbacea was similar in 2005. and change of distribution area of there was increased compare with 2005, as well that of Zoysia sinica was decreased in 2006. We suggested that pattern and process of halophyte communities are significantly related to hydro-geo-morphological condition of salt marsh ecosystem. Therefore, it is necessary to monitor in long-term period in order to clear the relationship between physical and biological environments in salt marsh ecosystem.
