Abstract Five research polygons along the transect "Yamal" were under study within the framework of several IPY projects (TSP, CALM, GOA) covering five bioclimatic subzones from northern taiga in the south through to the Arctic tundra in north. Measurements were performed on study sites during 1-3 summer seasons within standard plots characterized by relief, geological structure, surface properties and cryogenic processes. The plots are equipped for measurement of ground temperature, depth of seasonal thaw, vegetation indexes and other parameters of vegetation. Plant communities are described. The zonal patterns in the spatial distribution of various parameters of cryolithozone and biota, as well as manifestations of cryogenic and biotic components within geosystems are presented. It is established that, on the whole, zonal distribution of bioclimatic subzones northward determines the consecutive change of various parameters of vegetation, and permafrost. However, local factors connected to relief, drainage degree, location of plots on different landforms determining snow accumulation distort zonal pattern which is much more apparent when similar landscapes are compared. Application of quantitative methods of vegetation study has allowed to consider its interrelation with components of cryolithozone. The zonal changes of vegetation indexes, depth of thaw, and ground temperature from south northward in similar landscape conditions are determined by the reduction of biomass in this direction. The zonal pattern is clearer traced within the landscapes on clayey soils.
