摘要：By comparison the soil physical and chemical characteristics and heavy metal content of 6 forest rehabilitation sites in Shunde District, Foshan City, Guangdong Province, were studied and analyzed. The results showed that the soil bulk density was heavy in all the 6 sites. The soil structure and holding water-fertility capability was the best in Jun’an followed by Longjiang and Daliang was the worst. The soil organic matter, total N, cation exchange capacity, base cation concentration and pH value showed a tendency to reduce with the different ways of silviculture from no rehabilitation to rehabilitate completely. The soil nutrient elements were losed slowly in forest rehabilitation prophase. In all sites, the soil cadmium(Cd) and plumbum(Pb) contents overstepped third scope of environmental quality standard for soils (GB 15618-1995) and nature background value respectively, reached heavier pollution and lightly pollution. The environment loading capacity of soil for heavy metals did not show the obvious correlation with the silviculture methods. In the initial stages of forest rehabilitation, the soil environment qualities were not diverged from that of before rehabilitation. Planting native broadleaf tree species had great significance to protect forest soil from heavy metal pollution and raise environment capacity.
