三峡库区柑橘园土壤重金属行为特征研究

Study On heavy metal behavior characteristics of soil in citrus orchar ds of the Three Gorges Reservoir Region

  • 摘要: 试验研究三峡库区奉节县、忠县、长寿湖和江津市柑橘园土壤重金属行为特征结果表明,0~30cm土层土壤全CA、有效镉含量显著高于30~60cm 土层,说明三峡库区柑橘园土壤已受到CA 污染;三峡库区柑橘园土壤重金属源于成土母岩,柑橘园黄壤全cu、全cr、全Zn和全As含量显著高于紫色土,而有效锌、有效镉、有效铜和有效铅含量显著低于紫色土。柑橘园紫色土中有效镉占全量百分比达30.39% ,黄壤中有效镉占全量百分比仅为2.30%。

     

    Abstract: The heavy metal behavior characteristics of soil in citrus orchards in Fengjie County,Zhong County,Changshou Lake,Jiangjin City of the Three Gorges Reservoir Region were studied.The results show that the content of CA in 0~30cm soil is obviously more than that in 30~60cm so il.It proves that the soil has been polluted by CA .The heavy metal of the citrus soil in the Three Go rges Reservoir Region comes from the rock.The total content of Cu,Cr,Zn,and As in the yellow soil is much more than that in the purple so il in the citrus orchard,while the available content of Zn,CA ,Cu,and Pbin the yellow soil is much smaller than that in the purple soil in the citrus orchards.The propo rtion of available content to total content of CA in the purple soil in the citrus orchards is 30.39% .while that in the yellow soil is 2.30%.
