| Реферат: | eng: Increasing by 2.5 times the number of portions in preliminary division of the territory in accordance with the faunistic classification has resulted in lower correspondence between the defined latitudinal belts and zonal boundaries. This affected the area of Central (temperate) region due to its expansion farther north and inclusion of East Siberian mountain enclaves, parts of forest-tundra and true tundra landscapes with addition of the entire Chukotka Peninsula in northeast. Expansion of a similar scale takes place in the south of the region at the expense of the territories adjacent to Black and Caspian seas as well as Caucasus area and most of the forest-steppe zone. With finer division of the initial regional grid, the classification algorithm used in the study results in concepts, which are more generalized on a regional scale. The consequent division would detail the result of classification. Finally, we conclude that increased number of portions of relatively equal area better shows the continuality and provincial specifics of fauna, whereas the decreased number of portions of bigger area better reflects zonal differences.
