| 摘 要： | 本文主要根据不同的概率分布情况采用不同的统计方法，研究出黄河中游干流泥沙中Ｃｕ、Ｐｈ、Ｚｎ、Ｍｉ、Ｃｒ、Ｃｄ六种重金属元素的背景值，为保证其方法及数据的可靠性，将所测得的数据统计方法进行检验，并将黄河中游于流泥沙的背景值同国内外一些地区或流域土壤中同种元素背景值进行比较，数值基本在其所列范围之内；采用对因子序列综合法求出权值，并将泥沙现状作出评价。

| Abstract: | This article presents background values of six heavy metal elements Cu,Pb Zn,Ni,Cr,Cd,on sediment in the midstream of the Yellow River.Various statistical methods are used to obtain the data of these elements according to their various distributions of probability.In order to re-assure the reliability of methods used and data. The used statistical methods have been tested.and the companson was done on the background values with the same elements on the sediment of several drainages in the world. The result shows that the background values of these elements are mostly in the listed ranges,and heavy metal contents on the sediment are related to hydrologic periods and size of the sediment.The contents are inversly proportional to the size of the sediment:the finer the size is,the higher the content is.this article,weighted values are also worked out to assess present level of contamination. |
