This report is an investigation of revestagation and secondary succession in the burned area. The forest fire occurred in Mt. Ch'olye on April, 1989. After logging of the burned pine tree, the seedlings of Pinus koraiensis were planted by the replaceable plant in there.
The results are summarized as follows : Dorminant species in the first year(B-1) after fire were Miscanthus sinensis var. purpurascens, Carex humilis and Duchesnea chrysantha and those in the second year(B-2) after fire Miscanthus sinensis var. purpurascens, Carex humilis and Lespedeza cyrtobotrya.
the biological spectra in both burned and unburned areas were H-D_1-R_5-e type. The indices of similarity showed that B-1 and B-2 was 0.667, B-1 and U 0.526, and B-2 and U 0.500. Degree of succession(DS) was 181, 345, 1090 and species diversity(H) 2.35, 2,73, 2.54 and evenness index(e) 0.61, 0.73, 0.73 and dominance index(C) 0.17, 0.11, 0.15, in B-1 and U site, respectively.
Biomass of B-2 site was higher than that of B-1 site. Litter amount(kg/m^2) of burned and unbrurned areas were 0.017 and 0.863.
Soil pH, content of total nitrogen, organic matter, organic carbon, and water holding capacity of burned area were higher than those of unburned area while content of available phosphorus, exchangeable pottassium, C/N ratio, and water content of unburned area were higher than those of burned area, respectively.
