| 摘 要： | Nine horizon samples of three soil profiles representative of Dystri-gelic Cambisol, Fibri-gelic Histosol and Relic Ornithosol were taken from Fildes Peninsula of King George Island, South Shetland Islands to quantitatively demonstrate the enrichment, migration and loss of the elements (Si, Al, Fe, Ca, Mg, Mn, K, Na and P) in soil horizons and their behaviour within profiles by application of the enrichment coefficient calculated in terms of the abundance of Ti. Six horizon samples of 4 other profiles randomly taken from the studied area were examined for calculation of the redistributing enrichment coefficient, which was applied for a better understanding of the element redistribution between soil and clay fraction along with soil development. The results showed that the enrichment, migration and redistribution of the elements varied strongly among the investigated soils and horizons, due to the differences of weathering degrees and moisture status, influences of sea bird activities, etc.
