摘　　要：采集青海湖地区沙柳河河谷灌丛14种主要植物,采用AAS分析了其中7种微量元素含量。结果表明,元素Cu、Mn、Co含量有较大的植物种间差异,7种微量元素中Se含量最小,Fe含量最大。元素Mn和Fe、Co、Ni之间都具有极显著的正相关性,即相互之间具有协同性作用。Collected 14 plants of dominant species from the valley shrub of Shaliu river in the area of Qinghai lake. The content of 7 trace elements in all plants was analysed by AAS. The results show that the content of Cu, Mn, Co have great difference in different plant species, and the content of Se is minimum in 7 trace elements, the content of Fe is maximum. The significant positive correlation existed in between Mn and Fe, Co, Ni, though, Mn can co-operate with other elements.
