Abstract: Soil samples from cultivated land around Bijie Thermal Power Plant and Bijie Fertilizer Plant were collected and contents of Zn，Pb，Cd，Ni，V，Cu，Cr and Co in soil were determined by ICP-MS，contents of As and Hg were tested by AFS.Tessier continuous duration method was used to analyze forms of heavy metals in soil.Results showed that Pb，Ni，Cr，V，Cu and As in soil mainly existed in form of residual state，with content of above 50.88%，followed by Fe-Mn oxide bound state and stable in environment；Co mainly existed in form of Fe-Mn oxides，and content of Co was 76.26%；Hg was mainly composed of strong organic bound state and Fe-Mn oxide bound state and had potential influence on environment；Cd was mainly composed of ion exchange and residual state，content distribution of Zn in each state was higher，and its bioavailability and potential exploitable state had a higher proportion，which had a great influence on environment.Soil in plant was polluted by different degrees of heavy metal pollution and potentially harmful，may affect quality and yield of crops and thus threaten production and local residents.
