This study was carried out to investigate the effect of the coverage and the afforestation on the suspended solid and the sediment yield in a forested area burnt in Kangwon, Korea in 2000. Lysimeters were installed in T-l (supplementary plantation), T-2 and T-3 (naturally restored forests), P-1 (artificial plantation), P-2 (plantation for timber production) and C-0 (control plot) to measure the suspended solid and the sediment yield after rainfall. Suspended solid and sediment yield are affected by the coverage and the afforestation, and increase in proportion to rainfall. Consequently, the coverage and the afforestation in the forest fire area have an effect on the suspended solid and the sediment yield, and the second disaster will occur, if there are no erosion control works. Therefore, the environmentally favoring erosion control works are necessary.
