| Summary: | In order to expand the possibilities of soil-cover remote monitoring and improve prognostic models of active-layer depth dynamics in connection with global climatic changes, the verification of correspondence between plant and soil components of subarctic landscapes is necessary. This is most relevant for the forest-tundra zone, where the variety and mosaicity of soils and vegetation is great due to its ecotonic position. The purpose of this work was to study the relationship of vegetation with the characteristics of cryogenic soils and the dynamics of the active layer in forest-tundra landscapes. Data were obtained during monitoring studies at key sites in diverse landscapes of forest-tundra in the vicinity of Labytnangi. It was revealed that the thickness of the organogenic horizons, as well as the value of the moss phytomass, determine the active-layer thickness. A close connection with relief and soils allows the use of vegetation as an indicator of the soil texture and the depth of active-layer occurrence and features. This work was supported by the Ministry of Education and Science of the Russian Federation within the framework of the state assignment No. 6.7696.2017/8.9 (field work and data analysis of Radchenko TA, Valdayskikh VV) and (data analysis of Morozova LM), as well as by RFBR research project No. 18-04-00714 (data analysis of Nekrasova OA) |
