Abstract: Dachang Mining is a famous tin production base of China.Nowadays,most of the abandoned mine tailings dumping grounds are uncovered,resulting in serious regional environmental problems.A field revegetation experiment,composed of 3 treatments,CK,adding in garbage compost,and covering with soil,was carried out on an abandoned tin mine tailing dumping ground at Dachang Mining.The tailings were first amended with garbage compost and soil,and then Leucaena leucocephala trees were planted.In the first 100 days,L.leucocephala on the tailings amended with garbage compost were found growing best.The results showed that the garbage compost significantly decreased plant uptake of heavy metals from the soil,indicating that in the process of vegetation restoration on tin mine tailings dumping grounds,garbage compost can substitute soil,and L.leucocephala can be planted as the pioneer species.
