The purpose of the study is to analyze the physical and chemical characteristics of soils from the forest fire burned area in Gyeongju National Park. According to the physical characteristics of soils, soil temperatures and soil moistures in reforestation area (site 2 and 3) and natural restoration area (site 4 and 5) were higher than in control area (site 1). In terms of chemical characteristics, hydrogen exponents (pH) in reforestation area and natural restoration area were higher than in control area. The rates of available phosphoric acid (P2O5) in control area and reforestation area (site 1) had high rates, but rates in reforestation area (site 2) and in natural restoration area (site 5) had low rates. The rates of accumulated organic matter (O. M.) in reforestation area and natural restoration area were lower than in control area. The percentages of total nitrogen (T. N.) were analyzed similarly in all study areas and soils from reforestation area and natural restoration area had higher cation exchange capacity (CEC) than from control area. Therefore these results determines that soils from the forest fire burned area are being restored to normal gradually.
