This study was carried out to analyze the vegetation and soil characteristic, and ordination between Calanthe discolor and C. sieboldii population, Jeju Island. The C. discolor population was classified into Cryptomeria japonica dominant population, Miscanthus sinensis dominant population, and C. discolor typical population. The C. discolor population was located in elevation of 156m to 430m, and C. sieboldii was located in elevation of 424m to 604m in Jeju Island. In the study sites, soil organic matter, nitrogen, exchangeable potassium, exchangeable calcium, exchangeable magnesium, cation exchange capacity, and soil pH were 30.05~53.58%, 0.74~1.64%, 0.80~1.95cmol$^+$/kg, 4.35~22.53cmol$^+$/kg, 4.00~6.63cmol$^+$/kg, 25.60~51.33cmol$^+$/kg, and 4.83~5.70, respectively. C. discolor population was found in the low elevation and steep sloped area that has less organic matter, total nitrogen, and cation exchange capacity than C. sieboldii population. C. discolor typical population was found in the high elevation area that has more organic matter and total nitrogen in the C. discolor. Miscanthus sinensis dominant population was found in the shade of west direction of japanese black pine. C. sieboldii was found in a high elevation and a gentle sloped area that has high percentage organic matter, total nitrogen, and cation exchange capacity.
