Abstract

A distinctive paleogeographic situation in the southern part of the Vitim Plateau, Transbaikal region, has resulted in the formation of landscapes featuring numerous heaving mounds and thermokarst depressions. The cryolithozone reacts to climate warming by reducing its area, while the temperature and depth of seasonal permafrost thawing are increasing. A soil profile differentiation identified in the heaving mounds and thermokarst depressions has led to changes in morphological and physicochemical properties of soils, which caused, in turn, a response of the biota.

低温对Vitim高原南部地区土壤生物区系的影响

摘要

Transbaikal地区Vitim高原南部地区的一种独特的古地理情况导致形成了具有众多起伏丘陵和热喀斯特洼地的景观。冻土带通过减小其面积对气候变暖作出反应，而季节性冻土的融化温度和深度在增加。在隆起的丘陵和热喀斯特洼地中发现的土壤剖面差异导致土壤形态和物理化学性质的变化，进而引起生物区系的响应。
