This study was conducted to inform basic data for management of abandoned mine that was based on soil heavy metal concentration of the non-rearing and the rearing sites in Guundong Mine which had been completed of improve contamination soils, and examined into standard plant which had tolerances about pollution that analyzed into its accumulated heavy metals contents in the wild plant of naked soil. Consider form the result of contents by depth of soils heavy metals in the non-rearing sites, S1 point judged by contaminated to heavy metals of tailing leach after weathering caused by rainfall and permeate in S1 point soils when restored rest of tailing in 1996 restoration project. Lead of S2 point was not contaminated seriously by restoration and S3 point considered that heavy metals which leach by rainfall in the contaminated soils in mine vicinity accumulated in the abandoned paddy through river. When heavy metals of rearing sites soils were examined from the view point of upside of mine point (SP1, SP2, and SP3) of same above the sea level, zinc (537.5 ㎎/㎏) content of SP1 point was highest, and copper (535 ㎎/㎏) and lead (141.5 ㎎/㎏) in the SP3 point were high. To considered as orderly plenty of heavy metals in the plant were respectively in order, Perilla frutescens var. acuta KUDO (SP1 and SP4)＞Artemisia princeps PAMPAN (SP2)＞Miscanthus sinensis ANDERSSON (SP5)＞Vicia angustifolia var. segetilis (THUILL.) K. KOCH. (SP2). Especially, there were plenty of heavy metals in P. frutescens var. acuta, so it judged as a standard plant which have tolerances about heavy metals pollution sites. Therefore, we need more study about the heavy metals accumulate ability of P. frutescens var. acuta in future.
