为了解大围山的土壤重金属污染现状，开发高品质的名优特产，以湖南浏阳大围山山地表层土壤（0～20 cm）为研究对象，通过采集5种类型山地土壤表层土样，分析测定土壤中微量元素铜锌镍铅含量状况。结果表明：Cu、Zn、Ni、Pb全量分别为10．66～40．98、43．49～119．39、7．06～38．55、32．12～68．82 mg/kg；含量的变幅分别为5．41％～50．89％、2．57％～40．76％、5．28％～59．79％、8．21％～24．23％。5个不同海拔的土壤类型中除了黄红壤处于尚清洁状态，其余土壤都达到了轻污染水平，其中灌丛草甸土的综合污染指数最大。%To know the current situation of soil heavy metal pollution in the Dawei Mountain and develop famous specialty with high quality , 5 types of topsoil (0~20 cm) from the Dawei Mountain in Liuyang , Hu-nan Province,were taken as research object to detect the contents of Cu , Zn, Ni and Pb.The results showed that the total contents of Cu , Zn, Ni and Pb were 10.66~40.98, 43.49~119.39, 7.06~38.55 and 32.12~68.82 mg/kg respectively .The content variation ranges were 5.41%~50.89%, 2.57%~40.76%, 5.28%~59.79%and 8.21%~24.23%respectively.Among the 5 soil types of different altitudes , only the yellow-red soil was clean ,and the other 4 were all lightly polluted .The comprehensive pollution index of meadow soil in scrub was the highest .
