Description
Summary:Seasonal changes of environmental factors around the moss vegetation such as snow drift, water supply and temperature were investigated in the vicinity of Syowa Station from February 1983 to January 1984. Topographical features around the vegetation are basically concerned in the formation of snow drift. After late September the depth of snow cover gradually decreased and in October the vegetation was partially exposed from snow. In early December water traces were recognized beneath the snow. In contrast with a decay of the snow drift, the water content of moss turves increased and reached a maximum value of 125.8% during the period from late December to early January. Each small moss colony composing the vegetation had its own pattern of water supply which was considered to be related with small streams from the drift. Referring to the water supply, temperature profile and moss growth were also discussed.
