The changes of soil microbial community were analyzed to assess their responses to the simulated forest fire in the microcosms composed of burnt, unburnt and autoclaved soils. Several kinds of microorganisms including the aromatic hydrocarbon degrading bacteria were inoculated for the remediation of the damaged microbial community and vegetation. In uninoculated microcosm hydrocarbon degrading populations decreased by fire and autoclaving, but soon they began to increase and restore the original levels after 3 - 4 months. The numbers of hydrocarbon degrading populations in the autoclaved soils (10:3~ lO:8H CFU . g-1 dry soil) were higher than those of the burnt soils (105~106 CFU. g-1 soil) and unburnt soils (106 CFU . g-I soil). Although the fluctuation ranges of hydrocarbon degrading population in inoculated microcosms were smaller than those in uninoculated microcosms, the population changes of burnt. unburnt and autoclaved soils were similar to those of burnt, unburnt, and autoclaved soils in uninoculated microcosms. Usually the populations in the inoculated soils maintained the higher levels compared to the uninoculated soils until 2~3 months. The total microbial activities in the inoculated microcosms maintained the higher level than that of the uninoculated microcosms. The microbial activities of burned soils showed higher activities compared to those of burned and autoclaved soils, but they became similar after 3~4 months.
