Siberia is a key region for study of the climate development in north-central Eurasia in terms of global climatic change. The relief creates a major orographic barrier for atmospheric streams influencing the regional altitudinal weather zonality. Systematic 55-year (1963-2017) weather observations along the 700 km N-S latitudinal transect across the southern Siberian plains and the adjoining ranges of the Altai-Sayan Mountains document progressing seasonal temperature and humidity shifts. Standard meteorological data from twenty meteorological stations in different topographical and natural settings with specific weather conditions document a rise of a regional atmospheric humidity balance reflected by the increased bulk annual precipitation rates in the mountain areas accompanied by pronounced seasonal air-temperature fluctuations. This regionally trend provides evidence speaking in favor of the strengthening climate continentality over Siberia, which is also manifested by the pronounced seasonal temperature regime with increased thermally positive and negative air temperature anomalies. A landscape response to a climate warming is particularly evident in the high mountain zone. The present thermal conditions with raised MAT contribute to the progressing melting of mountain glaciers and degradation of permafrost in the alpine zone, as well as aridization of the parkland-steppe areas that are being partly transformed into continental semi-arid to deserted steppes. The associated environmental transformations trigger shifts in the local biotopes and ecosystems, with an altitudinal expansion of taiga-forest into the alpine tundra belt and xerothermic grassland invasions in the foothills. The modern climate changes have a major bearing to the Altai-Sayans socio-economic development.

The article discusses the importance of the factors of the formation of the landscape structure and landscape diversity for the creation of a natural park for the purpose of nature protection and the development of recreational nature management. The results of landscape studies performed in the process of substantiating the creation of a national park of regional significance "Foothills of Altai" in the vicinity of the resort of Belokurikha (Altai Krai) are presented. Functional zoning of the territory of the projected natural park with the allocation of zones of special protection, regulated recreational use and traditional nature management, as well as the buffer (buffer) zone is proposed.

Представлены результаты ландшафтных исследований, выполненных в процессе обоснования создания в окрестностях курорта Белокуриха (Алтайский край) природного парка регионального значения «Предгорье Алтая». Предложено функциональное зонирование территории проектируемого природного парка с выделением зон особой охраны, регулируемого рекреационного использования и традиционного природопользования, а также охранной (буферной) зоны

Systematic 55-year (1963-2017) weather observations along the 700 km N-S latitudinal transect across the southern Siberian plains and the adjoining ranges of the Altai-Sayan Mountains document progressing seasonal temperature and humidity shifts. Regionally uniform trend provides evidence of the strengthening climate continentality over Siberia also manifested by the pronounced seasonal temperature regime with increased thermally positive and negative air temperature anomalies. A landscape response to a climate warming is particularly evident in the high mountain zone. The present thermal conditions with raised MAT contribute to the progressing melting of mountain glaciers and degradation of permafrost in the alpine zone, as well as aridization of the parkland-steppe areas that are being partly transformed into continental semi-arid to desertic steppes. The associated environmental transformations trigger shifts in the local biotopes and ecosystems, with an altitudinal expansion of taiga-forest into the alpine tundra belt and xerothermic grassland invasions in the foothills.
