Effect of the use of a mulching sheet for the prevention of soil erosion and revegetation on soil microorganisms was investigated in field experiments. Soil erosion was prevented and the vegetation was promoted by the mulching. Both the number and diversity of soil microorganisms also increased by the mulching practice. When the surface soil on a bare slope was coverd with the sheet, the soil temperature and moisture at the depths of 10 cm and 30 cm were higher under a mulching sheet than without it. The results obtained suggest that the restoration of the initial soil ecosystem was promoted by the mulching sheet, which increased the number and the diversity of soil microorganisms. Soil microbial biomass and the diversity of microflora can be used as initial indicators for soil formation on a bare slope.
