Tab. 2,3,4 Specific resistivity of calculated models for the soundings in Lapland

Geoelectrical soundings were carried out in 29 different places in order to find permafrost and to measure its thickness. In most places above timber Iine a permafrost thickness of 10-50 m was recorded. Permafrost was found at sites with thin snow cover during winter. Here, deflation phenomena on the summits of fjells indicate the occurence of permafrost, Vegetation type might be a good indicator of permafrost, too. It seems obvious that permafrost exists extensively on fjell summits of northern Finland.

为探测多年冻土（permafrost）并测定其厚度，研究团队在29处不同地点开展了大地电测深（Geoelectrical sounding）工作。在多数森林线以上的区域，记录到的多年冻土厚度为10至50米。冬季积雪较薄的地点均发现了多年冻土。此类地点中，冰蚀高地（fjell）峰顶的风蚀吹蚀现象表明存在多年冻土。植被类型也可作为多年冻土的良好指示因子。显然，芬兰北部的冰蚀高地峰顶广泛分布着多年冻土。
