Annotation
The means for improving of the information capacity of ecological maps have been discussed with special accent on zoocomponent usually underestimated. The concept of ecoregion has been applicated in the course of work on the new map "Bioms of Russia" (S 1 : 8 000 000). Three levels of mapping units has been proposed: 1) zono- and orobioms, 2) ecoregions, 3) regional bioms. The first one is based upon the dominance of one or several zonal vegetation types, zoocomponent being characterized by the share of different vertebrate classes in species diversity of animal population. The concept of ecoregion reflects provincial features of subdivisions such as formation diversity, ecological-coenotic spectra of plants, trophic-demension groups, genera diversity of animal population, presence of endemic species and relic communities. Regional biom (main mapping unit) is characterized by the dominating growth forms, coenotical composition of plant formations and by the original combinations of types of territorial animal groupings with the enumeration of prevailing types and their species composition.
