To assess the ecological state and anthropogenic transformation of the Taimyr soil cover, the composition and properties of soils in natural and technogenic landscapes were studied in the northwest of the Central Siberian Plateau and in the North Siberian Lowland. Highly skeletic lithostrats (Skeletic Technosols) and peat heavy loamy organolithostr...

The article presents the results of annual heat dynamics in the soils of the main forest types in the central part of the northern taiga subzone of West Siberia. The general patterns of temperature dynamics at different depths are described, and the features of the forest soils temperature regimes revealed. The characteristic features of soil tempe...

The features of coefficients of determination and coefficients of leave-one-out method for spatial vegetation model and spatial models of squared deviations are discussed. The properties of models are illustrated in key area for spatial model of Cladonia stellaris projective cover.

The results of the analysis of accident occurrence and oil contaminations area along the oil pipelines are compared with the length of the pipelines for landscapes of the West Siberian northern taiga. The possible influence of landscapes on the relative frequency of accidents and contaminated areas are discussed.

The features of continuous spatial modeling of two main characteristics of vegetation – richness (% of cover) and occurrence of species, based on statistical relations with spectral values of space-born image (Landsat) are considered. The simplest version of statistical model, ordinary linear regression was used in all cases. Two approaches of mode...

Distributed GIS developed to assess the soil carbon stocks (SOC) includes digital maps “Vegetation” and “Soil” of boreal zone of West Siberia, middle-scale soil maps of the key sites of landscape provinces that have been created on the basis of interpretation of satellite images, and the software for updating and management of the database “Carbon...

A classification of northern boreal light coniferous forests in the West Siberian plain has been developed using the Braun-Blanquet approach. In the northern part of the West-Siberian plain, boreal coniferous forests occur at the northern limit of their range characterized by a cold continental climate and the prevalence of long-frozen, poorly drai...

Classification of northern boreal dark coniferous forests in the West Siberian plain was developed using the Braun-Blanquet approach. In the northern part of the West-Siberian plain, boreal coniferous forests occur at the northern limit of their range characterized by cold continental climate and prevalence of long-frozen, poorly drained soils in w...

The spatial structure of the fir undergrowth vs. to the fir, aspen, and birch trees in the climax community of the fir-aspen-birch forest was analyzed by the method of R-functions. The analysis showed that the fir undergrowth is primarily concentrated near old fir trees, but near the fir stumps it is more rare than expected. This distribution of th...
