LI Geng-fei(Weinan Teachers University,Shannxi,Weinan 714000)  
[Objective] The research aimed to determine the plant species that could Absorb all sorts of heavy metal and establish the man-made wetland ecosystem.[Method] The soil of abandoned gold mine around Tongguan County was chosen as the research object,and the type and the degree of the heavy metal in polluted soil were determined.[Result] For the soil samples with different distance and different depth,the content of heavy metal As Hg,Cd were more than the highest value of content standard of the heavy metal in the soil.The content of the heavy metal Pb in the surface soil was higher,and lower in deep soil.Metal elements of Zn and Cr were within the permitted content of the heavy metal in the soil.The radioactive elements Rb in the soil samples with different distance and different depth was detected,whose content was 78-88 mg/kg.[Conclusion] The heavy metal element must be considered for the ecological restoration in mining area.The Absorption of Pb in surface soil should be mainly focused on.The influence of Zn and Cr could be neglected.
