| 摘 要： | 为研究大兴安岭北部林区多年冻土Cu、Pb元素分布特征,文章利用X射线荧光光谱法,对冻土36个样点144个样品进行了Cu、Pb元素含量测定。结果表明,Cu元素含量范围在12.0~19.0mg/kg之间,Pb元素含量范围在14.0~25.0mg/kg之间。在不同冻土层深度、不同坡位、不同坡向上,其冻土Cu、Pb元素含量差异显著,其对冻土Cu、Pb元素含量影响由大到小排列顺序为土层深度>坡向>坡位。

| Abstract: | In order to study the Cu and Pb elements background value of permafrost in the north of the Daxinganling Mountains.There are 144 samples in 36 plots were tested with x rays fluorescent spectrometry.The content of the Cu was from 12.0 to 19.0 mg/kg and the contend of the Pb was from 14.0 to 25.0 mg/kg. It showed that there was significant difference in the content of the Cu and Pb in the pertnafrost,with the different soil depth,slope position and slope aspect,and their effect on content was soil depth>slope aspect >slope position. |
