抄録

In the course of writing this paper the physical environment of the Daisetsu Mountains, that is related to the development of alpine permafrost and periglacial landforms, is described. The climatic environment of the Daisetsu Mountains is elucidated on the basis of long-term meteorological observations from 1985 to 1986. Taking the air temperature condition and the pattern of the winter snow distribution into consideration, the distribution of permafrost in the Daisetsu Mountains is discussed. Then, the characteristics of the permafrost environment and the possibility of occurrence of periglacial landforms in the Daisetsu Mountains are discussed in relation to freezing and thawing indexes. Consequently, the active existence of permafrost and periglacial landforms such as palsas and frost crack polygons can be explained by the present climatic environment of the Daisetsu Mountains.
