Heavy metal concentrations including Cu，Zn，Cr，Cd，Pb，Ni，As，Hg in agricultural soil of Nanxue village,Yuncheng city were investigated to analyze its spatial distribution and pollution sources.Compared with the provided standards in the level 2 of China Soil Environment Quality Standards,the percentages of soil Hg and Ni contents were 16.50% and 1262% higher respectively,while the soil Cd，Pb，As contents were below the thresholds of the soils quality standards.According to the single pollution index evaluation results,the major pollutant was Hg,and its pollution index was 1.58 which reached a slight pollution level.The single pollution index of other heavy metals were less than 1,which were safe.According to the Nemerow integrated pollution index evaluation,6165% of the heavy metal contents in agricultural soils was in a safe level,18.45% was in the cordon,15.53% was in moderate or severe pollution,and only a little soil was in light pollution.The nugget effects of soil Zn,Cr,Ni and As contents were between 25% and 75%,which indicated that the spatial distribution of soil Zn,Cr,Ni and As contents were influenced by pesticides,fertilizer and material factors together.Meanwhile,the nugget effects of soil Cu,Cd,Pb and Hg contents were larger than 75% which indicated that the spatial distribution of soil Cu,Cd,Pb and Hg contents were primarily controlled by manure,sewage,automobile exhaust and residents living.Different ways of agricultural production among different regions can cause the significant difference of spatial distribution of heavy metal concentrations,which is of great significance on guiding the rational allocation of resource,scientific management of agricultural production and crops security.
