SUN Jing et al(Physical and Chemical Department,Heihe College,Heihe,Heilongjiang 164300)  
[Objective] The aim is to detect the heavy metals in the soil of Zhangdiyingzi and comprehensively assess its heavy metals pollution.[Method] The content of Hg、As、Cd、Cr、Cu and Pb in three functional zones under different and same land use background is studied,the relationship between heavy metals and different land use as well as sampling depth is analyzed.The overall heavy metals pollution status is evaluated.[Result] The soil has been contaminated by heavy metals,especially in the surface soil zones.The content of Hg is high and should be paid more attention.But the soil is at clean level on the whole,which could meet the needs of producing green food and vegetables.[Conclusion] The study accumulates scientific bases for us to understand the heavy metals pollution in the soil of this area,and lays the foundation for enlarging the planting areas of non-pollution grains and vegetables as well as promoting local agriculture.
