Abstract:Samples collected around reclamation land of Huainan coal mine were analyzed on the concentration of heavy metals(Cd,Zn,As,Ni,Cu,Pb,Cr,Mn) in the soils under different land use patterns(wheat field,peach ochard,vegetable greenhouse and rape field).The results showed that the concentration of heavy metals Zn,Cd and As in soil from reclaimed coal mine was 4.38,2.57,2.20 times of reference soil and there was a rather large difference of the accumulation of soil heavy metals under different land use patterns.The concentration of Zn,Cd,As in wheat field and peach orchard are higher than that in the vegetable greenhouse and rape field.The Cr concentration in vegetable greenhouse and peach orchard are higher than that in the wheatland and rape field.The difference of concentration of heavy metals of Ni,Cu,Mn,Pb under different land use patterns was not significant.Land use types,fertilization and coal mining activities were the main reasons leading to the difference of heavy metals concentration in soils under different landuse patterns.The order of soil heavy metals concentration risks in soils is as Cd>Zn>As>Ni>Cu>Pb>Cr>Mn while the highest is the Cd concentration in reclaimed soil(89.71).The ecological risks in different land use pat terns is as wheat feild>peach orchard>vegetable greenhous>rape field.
