摘要
Abstract
[Objective] The research aimed to study the distribution characteristics of heavy metal forms,reveal the influence of heavy metal contamination on soil,and clarify the correlation between heavy metal forms and physical and chemical properties.[Method] The Tissier synchronization extraction procedure method was used to analyze the content of the cadmium forms.Correlation analysis of Pearson between forms of cadmium and physical and chemical properties was done with SPSS.And linear regression simulation was done between cadmium forms and its major impact factors.[Result] Cd was mainly in residual fraction,exchangeable and carbonate combined and the content of the three forms accounted for 91.40％ of the total.The content of the labile fractions was higher and amounted to 40.09％ of the total.[Conclusion] The forms of cadmium had bioavailability and potential risk.In soil environment,more attention should be paid.pH was the dominant factor which affected the content of heavy metal forms of the cadmium.In addition,the forms of cadmium were affected by CEC and organic matters.关键词
