摘要(Abstract):
通过对广东省徐闻县113个农用地表层土壤样本的采集和分析,探讨该区域内硒含量的空间分布情况以及受到的影响因素。结果表明:该区域耕地土壤中硒元素含量在0.04~0.82 mg/kg,硒含量平均值为0.32 mg/kg;其中暗黄棕壤土壤中硒元素平均水平为最大,达到0.41 mg/kg;从地理区域看,位于南部的南山镇和与其相邻的徐城街道和城北乡硒平均含量明显高于其他乡镇地区,硒含量分别为0.51,0.41,0.42 mg/kg。不同母质类型的土壤中硒元素含量明显不同。滨海冲积物的平均硒含量最高,达到0.35 mg/kg,其次为玄武岩开发的耕地,平均硒含量为0.30mg/kg。综上,土壤类型和土壤母质可能是影响硒含量分布的重要因素。
