摘要:

Icings on the Putorana Plateau were studied using satellite imagery; the laboratory interpretations were verified from the air under field conditions. Over 200 icings have been recorded, with a total area of about 2000 km2. The majority of the groundwater icings are located at altitudes of 500–600 m, and the volume of ice contained in them totals 3 km3. River and snowmelt icings are widespread. Taking these icings into account the total volume of ice in the Putorana icings amounts to about 5 km3; the relative area occupied by icings is 0.7%; and icing runoff amounts to 12 mm. Icings have a major impact on the morphogenesis of river valleys and on the vegetation, and produce a characteristic landscape. A map of icings on the Putorana Plateau at a scale of 1:1 million has been compiled.
