Биомная дифференциация российской Арктики

Abstract

The article discusses various aspects of the biome division of the Russian Arctic and its significance for assessing climatic and anthropogenic changes in ecosystems. Different authors base the biome differentiation of the Arctic on the zonal-provincial principle, which takes into account the latitudinal temperature gradient and the meridional gradient of the continentality of the climate. As a result, from 6 to 20 or more biomes are allocated directly for the Russian Arctic to assess conveniently biodiversity, the response of ecosystems to climate change, to form a representative network of protected natural areas, etc. To characterize the climate and biodiversity, the authors use the schemes of biome division of the Russian Arctic, presented on the existing versions of maps of Russian biomes [10; 18]. They give quantitative characteristics of biomes that are important in relation to the regulation of economic activity and optimization of the territorial protection of biota and ecosystems in the Arctic.
