Abstract
The sediments of the tidal flat and the reclaimed land were compared in terms of physical and chemical properties, and studied the factors affecting the changes with regard to the relationship of the tidal creek distance and vegetation. The study area, reclaimed ten years ago, is located in KIMPO LANDFILL SITE stadding kimpo-kun, kyonghi-Do and Paeksok-Dong, Inchon. Five sites were selected for the study, One is in the tidal flat and the others are in the reclaimed land. Five undisturbed samples were cored with vibracoring equipment. Each sample was 120㎝ high and analyzed the sediment's physico-chemical properties in 5㎝ units. The plant species and organic matter contents were investigated to find out the relationship between the physico-chemical properties and the vegetation. The major findings were summed up into the followings. First, from the grain-size analysis, the ration of the sand, silt, and clay was 1.80%, 61.09% and 37.11% in the tidal flat smaple and 3.20-6.15%, 75.52-87.08% and 9.71-18.33% in the reclaimed land. Less clay percentage in the tidal flat seems to result from the clay eluviation or the deposition environmental change after reclamation. However, it was not clear in this study. According to the U.S. Department of Agriculture's classification standards, the sediment of the sample sites was classified as silty-clay loam in the tidal flat, and as silt and silty loam in the reclaimed land.
