摘要
作者选择了当地代表性植物:羊草(Aneurdepidium chinense)、针茅(Stipa)、冷蒿(Artemisia frigida)和锦鸡儿(Caragana),共51品,分析得出微量元素Cr、Pb、Cd、As和Hg的草原背景含量。研究表明,这四种植物对上述微量元素选择吸收的顺序完全一样。
The background values of Cr, Pb, Cd, As and Hg from 51 samples of the local native representative plants as Attea rdepidian chinense ,stioa, Artemisia frigila and caragtna have been analyzed. The results indicated that the orders of the four plants to sclcc-tively absorb these elements are almost the same.
