This study was conducted to know the effect of major physical-chemical characteristics of soil to be in the area of indigenous and naturalized plant in the sand dune of the western coastal area of Korea. The study was performed on the sand dunes distributed across Taean-gun and Buan-gun and the study period was from April to October in 2010. Sixty nine of 5 m × 5 m study plots were installed and the distribution of plants were investigated. We measured the soil characteristics including soil pH, organic matter, total nitrogen, available P2O5, soil cation exchange capacity, exchangeable cation, EC and NaCl. As a result, soil texture was classified as sand, in case of average pH, NaCl, and EC of soil to be in the area of indigenous herbaceous plant were 7.77, 0.03% and 0.52 ds.m-1, indigenous woody plant of the mean pH, NaCl and EC were 7.31, 0.01%, 0.23 ds.m-1. In case of naturalized herbaceous plant of the mean soil pH, NaCl and EC were 7.12, 0.01%, 0.29 ds.m-1, naturalized woody plant of the mean soil pH, NaCl and EC were 7.34, 0.01%, 0.20 ds.m-1 respectively. On average, naturalize plants showed in low salinity concentration than indigenous plants.
