| 摘 要： | 对广西某喀斯特流域内土壤和岩石样品中的Cd元素含量进行分析测试,研究流域内土壤重金属Cd的分布特征和来源。结果表明,流域土壤中Cd含量变异较大,为0.10~33.00 mg·kg-1,插值图显示流域中游地区土壤中Cd含量较高;流域内岩石中重金属Cd含量范围为0.19~1.08 mg·kg-1,流域土壤中Cd元素具有较高的地球化学背景值。研究表明,流域内土壤重金属Cd的主要为自然地质源,其次是人类活动的干扰。

| Abstract: | In this article, the Cd contents of soil and rock were determined in karst basin of Guangxi district. This study demonstrated that Soil Cd concentration in the basin was in range of 0.10~33.00mg?kg-1 ,the interpolation figure show that Cd content in soil is higher in middle region; Cd content in rock of the basin was in range of 0.19~1.08 mg?kg-1, Cd elements in soil of basin is of high geochemical background values. It is mainly derived from the geogenic causes source S,followed by the interference of human activities. |
