Abstract:

 The distribution,interrelation and ratio of chemical elements are discussed according to the chemical composition of the moss and lichen in this area. Results show that moss and lichen promote the weathering of soils,though the biogeochemical process is quite slight because of the Antarctic environmental condition. The concentrations of Fe,Al and Mn are primarily controlled by the background level in the underlying soils.Ca,Mg,K,Na,S and some trace elements are selectively absorbed by moss and lichen,but their absorptivities are different. Ca,K and Cr are the elements that can be strongly absorbed by lichen while Mg,Na and Zn are strongly absorbed by moss.
