Abstract: Studies on the nourishing properties of geochemical elements in Antarctic mosses and lichens show that potassium and calcium were the most active elements,while phosphorous was accumulated in the middle part of lichen cells,and participated in organic synthesis.Mosses accumulated sulphur stressly,but took in iron and magnesium negatively.Aluminum and silicon were absorbed passively by lichens.It is concluded that potassium and calcium were the important nutrient elements for the growth of mosses and lichens,sulphur and phosphorous were the middle significant nutrients,while aluminum and silicon were the passively accumulated elements.
