摘　　要：土壤重金属污染是土壤环境污染的重中之重,不同的重金属评级方法评估结果差异较大。为考察光明食品集团在上海崇明和奉贤区域的土壤重金属污染情况,采用地积累指数法,以国家和上海市土壤重金属背景值为计算依据,按照地积累指数评价与分级标准,分析典型区域重金属积累情况并进行评价。结果表明:崇明区域8种重金属平均含量依次为Cu 23.61 mg∕kg,Zn 88.34 mg∕kg,Pb 12.38 kg∕kg,Cd 0.11 mg∕kg,Cr86.82 mg∕kg,Ni 27.59 mg∕kg,Hg 0.1 mg∕kg和As 8.71 mg∕kg;奉贤区域重金属平均含量依次为Cu 21.18 mg∕kg,Zn 103.13 mg∕kg,Pb 12.59 kg∕kg,Cd 0.13 mg∕kg,Cr 85.03 mg∕kg,Ni 19.71 mg∕kg,Hg 0.08 mg∕kg和As 8.85 mg∕kg。整体而言,光明食品集团国营农场崇明和奉贤区域的农田土壤重金属均处于安全范围内;地积累指数分级频率因评价标准值的差异而有所不同,8种重金属(Cu、Zn、Pb、Cd、Cr、Ni、Hg和As)未造成污染,Igeo均小于0,说明光明食品集团上海崇明和奉贤区域的国营农场土壤质量安全。Soil heavy metal pollution is a very important point of soil environmental pollution, differentheavy metal rating methods lead to different results. The aim of this paper was to evaluate the pollution of heavymetals in state farm soil of Bright Food Group in Shanghai suburbs（Chongming and Fengxian District）. Based onthe background value of soil heavy metals in China and Shanghai,according to the geoaccumulation evaluationand grading standards,accumulation and evaluation of heavy metals in typical areas were studied by using theindex of geoaccumulation（Igeo）. The results showed that the average contents of soil heavy metals in Chongmingwere Cu 23. 61 mg∕kg,Zn 88. 34 mg∕kg,Pb 12. 38 kg∕kg,Cd 0. 11 mg∕kg,Cr 86. 82 mg∕kg,Ni 27. 59 mg∕kg,Hg0. 1 mg∕kg and As 8. 71 mg∕kg,respectively; those in Fengxian were Cu 21. 18 mg∕kg,Zn 103. 13 mg∕kg,Pb12. 59 kg∕kg,Cd 0. 13 mg∕kg,Cr 85. 03 mg∕kg,Ni 19. 71 mg∕kg,Hg 0. 08 mg∕kg,and As 8. 85 mg∕kg,respectively.Generally speaking,soil heavy metals contents in Chongming and Fengxian of Guangming Food Group were in asafe range. The classification frequency of 8 heavy metal elements was different according to the difference ofstandard values,the contents of Cu,Zn,Pb,Cd,Cr,Ni,Hg and As in soils were classified as no pollution degree,with the value ofIgeo〈 0. The soil quality of Bright Food Group state farm in Shanghai suburbs（Chongming andFengxian）was safe.
