Abstract
A conceptual model of the climatic dependence of structural biodiversity of boreal forests of Northern Eurasia is developed; the coordinates "continentality - warmth" are used, along with the ordination of zonal types of forest lands plotted in the same system previously. The basis of the portrait ordination model was composed of the landscape-important biomorphocycles of biocenosis types, which play a leading part in zonal complexes of forest types. The most characteristic features of longitudinal sector and latitudinal zonal changes of cycles and biomorphocycles in the space of two-dimensional bioclimatic model of the forests of Northern Eurasia are shown.
