Research Abstract	We practiced the revegetation test of the site of limestone mine using four Lauraceae and two Fagaceae woody species. These species were distributed on the limestone area. Four Lauraceae species planted on the site of limestone mine accelerated their growth. However, Cinnamomum camphora was suppressed its growth at the block where large amount of limestone were fallen. Growth of Neolitsea sericea was not suppressed its growth at this block. Seedlings of four Fagaceae were inoculated two species of ectomycorrhiza (Astraeus sp. and Scleroderma sp.). Two Quercus salicina and glauca inoculated Astraeus accelerated their growth.
