Summary The general geographic regularities of the distribution of the biological productivity of the plan cover, (1) the reserve of green assimilating elements, (2) the total annual increment (in the above-ground and underground spheres), and (3) the annual increment in green assimilating elements, are subject to climatic factors, at the same time being determined by the biological characteristics of the plants. The values of these indices for zonal vegetation types are primarily regulated by the heat and moisture ratios. An increase in the indices of the total annual increment and also the increment in green mass of the plant communities is observed from the northern to the southern latitudes. The significance of the third major factor, which determines the living conditions of the plants, namely the influx of nutrients, is manifested particularly clearly in an analysis of the productivity indices of the intrazonal types of plant communities, under the conditions of cumulative land areas.
