摘　　要：土壤重金属污染在世界范围内广泛存在且日趋严重,全世界平均每年排放汞约1.5万t、铜约340万t、铅约500万t、锰约1500万t、镍约100万t[1]。中国受汞、铬、镉、铅、镍等重金属污染的耕地面积已达2000多万hm2,约占总耕地面积的1/5[2],每年受重金属污染的粮食约1200万t[3]。中国城市土壤也存在重金属污染问题。重金属污染土壤的修复已迫在眉睫。Soil heavy metal pollution is increasingly severe worldwide, the global average annual emission of Hg, Cu, Pb, Mn, Ni were 15 thousand tons, 3.4 million tons, 5 million tons, 15 million tons, and 1 million tons respectively. The area of farmland contaminated by heavy metal was about 2000 hm^2 in China, accounted for 20% in total, grain contaminated by heavy metal was about 12 million tons every year. Urban soil contamination is also severely in China. It＇s top urgent for us to solve restoration of heavy metal contaminated soil.
