Abstract: Four different types of agricultural lands, i.e. upland field, woodland, paddy field and vegetable garden, were selected in Fuyang city, Zhejiang Province, as subjects for study on contents of seven heavy metals, i.e. Cu, Zn, Pb, Cd, Ni, Hg and As, in 0-20cm surface soils for assessment of heavy metals pollution of these soils using the Nemerow composite index method, and for exploration of effects of land use on the pollution. Results indicate that the average content of Cu, Zn, Pb, Cd, Ni, Hg and As in the soils was 26.01, 108.41, 36.42, 0.26, 21.85, 1.66 and 94.81 mg•kg^-1, respectively, and the single pollution indices of Hg and As were much higher than the others’. In terms of the Nemerow composite index, the four types of land use are in the order of vegetable garden , upland field ,paddy field and woodland. The upland field is the higher in Cu and Zn content, and the vegetable garden was highest in Pb and the lowest in Hg. Differences between the lands in Cd,Ni and As were not significant. The disjunctive Kriging risk assessment shows that lands with w(Hg)>0.3 mg•kg^-1 and w(As) >30 mg•kg^-1 are high-risk areas, which are agricultural lands, distributed mainly around cities,towns and industrial and mining sites, suggesting that the Hg and As pollution is closely related to human activities.
