Abstract:

Fifteen-five kinds of vegetation samples were collected in desert area, and the contents of major and minor elements were analyzed based on the X-ray fluorescence methods. The results indicate that major elements contained in the desert vegetation are Cl, S, P, Ca, Si, Al, K, Na and Mg. Minor elements contained are Sr, Rb, Br, Zn, Cu, Ni, V, Ti, Ba, Mn and Fe. Different kinds of plants have different contents of elements, which indicates that plants have selective absorption of geochemical elements. The desert plant samples are rich in Ca, K and poor in Na, indicating unified influence of habitat on the chemical components of various plants. The chemical element contents of the plants in same family are similar, which shows that the chemical components of plant can be used as one of the indicators for plant classification.

Key words: desert area, vegetation, major element, minor element
