摘要

A large spectrum of biogeocenoses is typical for the territory studied: it ranges from forests to high-mountain tundra. This is explained both by the vertical zonality in the mountains and by the transitional position of the area-at the boundary between the forest-tundra and the northern taiga. Hence, the soil cover is very complicated and diverse. Of special interest are the forest massifs at their northern limit, and as all transitional ecosystems, they have a high ecological importance at both regional and global scales [1]. The soil cover of the Khibiny Mountains is discussed in many publications [2-4]. Along with the soil cover, the biological cycling was the object of studies that were performed in different vertical vegetation belts [5-8]. Itwas found out that the soil cover of the mountain forest belt is composed to a considerable extent by podzolized soils [9], and the intensity of the podzolization, or alfehumus, process increases downslope from the birch elfin woodland to the forest belt. Although the latter has the maximum phytomass as compared to the other mountainous belts, its biological cycling is somewhat hindered [10]. Soils of the forest belt are characterized by a prominent eluvial-illuvial profile differentiation, rather highhumus content, and low content of nitrogen; they are moderately acid and have a low base saturation [11]. Among three vertical vegetation belts (tundra, birch elfin woodland, and forest), the forest belt is the least known in the Khibiny Mountains as are many other mountain forests of the northern taiga, and particularly in terms of vegetation and soil cover interrelations.
