the original meaning of “areas peripheral to Pleistocene ice sheets and glaciers” (Lozinski 1909) to one which stresses the distinctive processes of freeze-thaw and permafrost formation. In spite of the comment by Worsley (2004) that the term periglacial has no universally accepted definition, there are really only two options that are in common use: a) an environment of frequent freeze-thaw cy...

the objective of this study was to assess the relationship betweenvegetation, landform and physicochemical properties of soil. at the first terrainmap unit were provided using the landsat thematic mapper (tm) satellite images,aerial photograph, topographical and geology map. field sampling was done in therepresentative area using plot sampling. 104 plots 100 m2 were sampled in eachplot landform...

The Dry Valleys are subdivided into three microclimate zones on the basis of summertime measurements of atmospheric temperature, soil moisture, relative humidity and wind-speed/ direction. Subtle variations in these climate parameters result in considerable differences in process geomorphology and in the development of unique landforms within each zone. The mapped zones include a coastal thaw z...

The geological environment is important for the development of coal enterprises. In Guqiao coalmine, information mining subsidence, terrain landform, gangue utilization, mine water treatment and several on-site investigations have been analyzed. It holds that its can be evaluated from three aspects, i.e., disasters, landform destruction, influence on soil environment. results show activities se...
