Abstract

The results of the long-term monitoring (from 2008 to 2018) of thermal conditions have been applied to assess the ecotopological differentiation of vegetation in the exposure-related forest-steppe of Transbaikalia. Significant differences are revealed between thermal conditions on northern and southern slopes, as well as between different kinds of forest-steppe along the aridity and continentality gradients. The temperature conditions on southern slopes are relatively unified and determine the formation of vegetation of one steppe class: Cleistogenetea squarrosae. The temperature conditions on northern slopes are more heterogeneous and result in the development of plant communities of different classes: steppes of the class Cleistogenetea squarrosae and forests of the hemiboreal class Rhytidio-Laricetea and of the boreal class Vaccinio-Piceetea. Differences in soil temperature are additionally affected by the size of forest plots in the forest-steppe.

利用土壤热条件数据进行跨贝卡利亚暴露相关森林草原植被的分化

摘要

长期监测（2008年至2018年）热状况的结果已用于评估与Transbaikalia暴露相关的森林草原中植被的生态拓扑差异。南北斜坡的热条件之间以及沿干旱和大陆梯度的不同种类的森林草原之间存在显着差异。南坡的温度条件是相对统一的，并决定了一种草原类古生植物（Cleistogenetea squarrosae）的植被形成。北坡的温度条件更加不均一，并导致了不同种类植物群落的发展：Cleistogenetea squarrosae类的草原和半球形的Rhytidio-Laricetea和北方的Vaccinio-Piceetea森林。土壤温度的差异还受到森林草原中林地面积的影响。
