Abstract

This paper describes typical and humic petrozem soils developing in the most high-altitude (goltsy) zone of the Khibiny Mountains under three predominant types of primitive plant communities representing different stages of the primary succession. The profiles of such soils are not differentiated by the content of most elements, except for phosphorus concentrated in the surface organogenic horizons. By their chemical and physicochemical properties, soils of the cold mountain (goltsy) desert are similar to Entic Folic Podzols formed under dwarf-shrub vegetation in the mountain-tundra located downslope. The biological activity of petrozem soils is lower than or comparable to that in soils of dwarf-shrub tundra. It is established that the microbial activity increases and soil organic matter stabilizes when the vegetation becomes more patterned. Overall, microbial communities of petrozem soils are well adapted to extreme environmental conditions.

赤壁山脉的寒山（高地）沙漠海拔地区的土壤

摘要

本文描述了在三种主要原始植物群落类型（代表原始演替的不同阶段）下，在Khibiny山的最高海拔（高海拔）地区发育的典型且腐殖质的petrozem土壤。除磷集中在地表有机成因层之外，大多数土壤的元素没有区分这些土壤的概况。根据其化学和物理化学特性，寒冷的高山（高棉）沙漠的土壤类似于山坡苔原下坡的矮灌木植被下形成的Entic Folic Podzols。彼得罗泽姆土壤的生物活性低于矮灌木冻原土壤或与之相当。可以确定的是，当植被变得更加有图案时，微生物活性增加，土壤有机质稳定。
