Abstract
Salt marsh is a tide-stressed environment, grading from nearly terrestrial to marine in character. It has a distinct zonation of vegetation. The characteristics of salt marsh sediments was studies. Salt marsh sediments and mud flat sediments were compared in terms of physical and chemical properties. The study area is located in Kanghwa-Kun, Naega-Myoun, Oipo-Ri. Three sites were selected. One is in the mud flat, which is no vegetation. Another in the low rparsh, which represents the younger portion of the marsh, is characterized by Suaeda maritima. The other in the high marsh is characterized by Phragmites lonivalvis. Four undisturbed samples were cored with vibracoring equipment. Each samples was 100cm high and analyzed the sediment's physico-chemical properties in 10cm units. The concentration of total nitrogen(N) was analyzed to find out the ecological characteristics of salt marsh sediments. The tide pattern, and plant species were investigated to find out the relationship between physico-chemical properties and the tidal regime, vegetation. The major findings were summed up into the followings First, tide pattern of the study area is semi diurnal tide. Tide range of the study area is 3.2m - 10.2m, and tide velocity is faster than that of other areas. Mud flat is flooded almost every time, except during mean low-water spring tide. Low marsh is flooded fairly regularly. In contrast, high marsh is inundated only during spring tides or storm-related high-water.
