In order to examine the soil microbial activity of soils in an urban area, β-glucosidase activity, soil respiration rate and the amount of microbial biomass carbon were measured in soils from four parks in Kobe City. The soils were collected from three stands, bare ground, turf and forest, according to the land-use type. Soil microbial activity bases on the determination of the β-glucosidase activity and soil respiration rate, and the amount of microbial biomass carbon were highest in the forest soils, followed by the turf soils. The bare ground soils in all the parks showed a low activity and low values for microbial biomass carbon. Furthermore, the effects of the relative age of the parks on soil properties were examined in three parks, which had the same parent materials. In the bare ground soils, the microbial activity and the amount of microbial biomass carbon were the lowest, and did not change with time. In the turf soils, the values increased gradually with time. In the forest soils, these values significantly increased after about twenty years. It was found that the soil microbial activity and the amount of microbial biomass carbon in an urban area were affected by the land-use type, and that the activity and amount of biomass showed differences in the variation pattern according to the land-use type.
