The germination period, the germination under different saline concentration and temperature condition, the survival percent several halophytes in cross-transplanting experiment of marsh type and the soil environment factor of five dominant species were investigated on the halophytes population formation strategies on the salt marsh of Mankyeong river estuary from February to October 2005. In terms of germination, Suaeda japonica appeared first followed by Aster tyipolium Salicornia herbacda, Atriplex gmelini and Suaeda asparagoides. The germination percent on the humidify conditions and saline concentrations of halophytes were that Suaeda japonica germinated well under inundation conditions, high temperature and low salinity; Salicornia herbacda under high salinity; Aster tripolium and Atriplex gmelini under dry or inundation conditions, and Suaeda aspar agoides under dry conditions and high salinity. The survival percent in cross-transplanting experiment of five halophytes were high with Suaeda japonica in the low marsh; Salicornia herbacda, Aster tripolium and Atriplex gmelini in the mid marsh, Suaeda asparagoides in the high marsh. The soil properties were similar for the five halophytes, but soil texture appeared high in order of silt, sand and clay. These results suggested that population formation strategies of five halphytes. Suaeda iaponica was distributed in the low tidal marsh, Salicornia herbacda, Aster tripolium, Atriplex gmelini in the mid tidal marsh and Suaeda asparagoides in the high tidal marsh.
