摘要
分析了云南的哀牢山徐家坝地区黄棕壤中12种元素的背景值。讨论了成土母质类型和植被类型对土壤中元素的背景值的影响。
The 23 profiles(86 soil samples) were collected from Xujiaba area, Ailao Mountain, Yunnan. The elements in yellow brown earth (including Cd, Zn, Be, Cu, Ti, Mn, Co, Ni, Pb, V, Cr, and B) were analyzed by ICP and AAs. The types of probability distribution were studied and tested by KopmoropoB CMHPHOB VISTELIUS and Pearson X 2. The results shown that: Cd, Zn, Be, Ti, Cr, Pb, B are in normal distribution; Cu, Mn, Co, Ni are in logarithmic normal distribution, and V is in skew distribution. Thus the background values of these elements in yellow brown earth if this area were determined and tabulated. We discussed the influences of soil parent materials and vegetation types on the background values of elements in soil and came to conclusion that parent material is an important factors to influence the background values of elements; different plant species have various coefficients of biological absorption, different enrichments of plants also influence the background values of these elements.
