The soil samples in the studied area were collected and tested��for estimating the environmental quality of heavy metal pollution in soil�� According to the second level of agricultural soils standard in Soil Environ- mental Quality Standard (GB15618- 2008)��the environmental risk of Ni and Cd in soil was accessed by using sin- gle factor index and Nemerow index�� The results show that the pollution of Ni is in the range of 3 000 m to the e- mission center�� There are 15 points of heavy mental content in the soil beyond the standard��in which most of the excess areas are precaution domain or slightly polluted domain�� There exist severe pollution and integrated pollution phenomenon in some areas�� The authors analyzed the corn plants grown in the polluted areas�� The contents of Ni and Cd in the corn plants do not exceed the related standard level��indicating the pollution of the soil in this area has no impact on corn plants��
