| This study was carried out to examine the recovery of forest ecosystem by changes of soil chemical properties and soil microorganism at the burned areas of coniferous (Mt. Chocdae) and broad leaved forest (Samsinbong in Mt. Chiri). In the soil chemical properties of the burned area of Samsinbong, pH was 5.8, and contents of organic matter, total nitrogen, available P©üO/sub 5/, exchangeable K/sup £«/, exchangeable Ca/sup £«£«/ and exchangeable Mg/sup £«£«/ were 7.42%, 0.73%, 28.5 §·/§¸, 1.3 me/100g, 13.3 me/100g and 2.2 me/100g, respectively. But they showed a tendency to decrease with time. In the soil chemical properties of the burned area of Mt. Chocdae, pH was 5.3, and contents of organic matter, total nitrogen, available P2O5, exchangeable K/sup £«/, exchangeabe Ca/sup £«£«/ and Exchangeable Mg/sup £«£«/ were 6.42%, 0.25%, 24.4 §·/§¸, 0.7 me/100g, 3.7 me/100g and 2.1 me/100g, respectively, and they also showed a tendency to decrease with time. In contrast, they were not changed with time at the unburned areas. At the burned area of Samsinbong, soil microorganism showed to order of fungi (69¡¿10©ù CFU), actinomycetes (523¡¿10©ù CFU) and aerobic bacteria (291¡¿10©ù CFU), and at the unburned area, showed to order of actinomycetes (745¡¿10©ù CFU), fungi (594¡¿10©ù CFUU), and aerobic bacteria (160¡¿10/sup 4/ CFU). At the burned area of Mt. Chocdae, soil microorganism showed to order of fungi (676¡¿10©ù CFU), actinomycetes (434¡¿10©ù CFU) and aerobic bacteria (350¡¿10©ù CFU), and at the unburned area, showed to order of fungi (461 ¡¿10©ù CFU), aerobic bacteria (328¡¿10©ù CFU) and actinomycetes (319¡¿10©ù CFU). Soil microorganisms of the aerobic bacteria, actinomycetes and fungi appeared at the burned areas were much more abundant than unburned areas. The aerobic bacteria appeared at the coniferous forest were also much more than the broad-leaved forest. The actinomycetes and fungi appeared at the broad-leaved forest were much more abundant than the coniferous forest. |
