Abstract
The spatial divergence of climatic changes necessitates the creation of predictive models of the state of vegetation cover. Our proposed solution for the spatial modeling of the biological productivity of natural ecosystems creates the basis for a further quantitative assessment of the potential absorption of CO2, which is currently considered one of the most urgent environmental issues. In the proposed work, using the methods of geoanalysis of growing conditions, an original technology for modeling the potential spread of biocenoses and their productivity has been developed, reflecting the internal attractor of the development of biocenoses under the influence of local hydrological and climatic conditions of their growth. The methodology was implemented for the southeast of Western Siberia within the framework of publicly available GIS Saga based on a digital terrain model and data from the WorldClim 2.0 climate reanalysis. To forecast data for the period of the third decade of the 21st century, V.V. Paromov’s regional climate forecast was used on the basis of an adaptive model—the exponential smoothing method. The verification of the simulation results was carried out on the basis of the Productivity of Ecosystems of Northern Eurasia database. As a result, spatially distributed data were obtained in the form of rasters with high spatial resolution for the average long-term potential bioproductivity according to reanalysis data for 1970–2000 and predicted data for 2021–2030. Both positive and negative trends of potential bioproductivity for various natural zones of the southeast of Western Siberia due to the spatial divergence of changes in heat and energy resources and precipitation over the territory have been revealed. In general, warming in sufficiently drained areas contributes to an increase in the biological productivity of agro and biocenoses and, in hydromorphic areas, to a decrease.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
