摘要：

This study investigated palsa located at the southern margin of palsa extent upon the Kola Peninsula, Russia. Thirteen palsa bogs were analyzed, two of which had intervals between surveys of either 67 years (1935-2002) or 82 years (1920-2002). The thickness of the active layer of palsa during the warm season varied from 44 to 64 cm, consistent with existing data. The height and number of bog mounds, as well as the thickness of the active layer, are unchanged over the past 80 years. (C) 2010 Elsevier B.V. and NIPR. All rights reserved.
