Mongolian Plateau is a vast highland region in East Asia spanning parts of Mongolia, China, and Russia. The plateau forms a transitional zone between the Siberian interior, the Loess Plateau, and the Tibetan Plateau, and has shaped the movements of peoples such as the Mongols and the Turkic peoples. Its wide steppes, deserts, and mountain ranges have been central to historic routes like the Silk Road and have influenced events including the campaigns of Genghis Khan and the expansion of the Manchu states.

Geography

The Mongolian Plateau comprises broad steppe grasslands, the arid Gobi Desert, and several mountain ranges including the Altai Mountains and Khangai Mountains. Major rivers originating on the plateau include the Selenge River, which drains into Lake Baikal, and the Orkhon River, a tributary historically linked to the Khitan people and the Yuan dynasty. Cities and administrative centers on or near the plateau include Ulaanbaatar, Hohhot, Hailaer, Chita, and Zhangjiakou. Neighbouring regions and features include the Dzungarian Basin, the Hexi Corridor, the Tarim Basin, and the Yellow River watershed, which together define the plateau’s geographic context.

Geology and formation

The plateau’s geology reflects interactions among the Eurasian Plate, the Indian Plate collision, and intracontinental deformation processes active since the Mesozoic. Bedrock includes Precambrian shields, Paleozoic sedimentary sequences, and Mesozoic volcanic deposits tied to events like the Siberian Traps magmatism and later Cenozoic uplift. Tectonic uplift associated with the continued northward motion of the Indian Plate and intraplate stress fields produced fault systems and basins similar to those in the Tarim Basin and the Yangtze Craton. Quaternary loess deposits and aeolian sediments cover much of the surface, as in the Loess Plateau, while glacial landforms in the higher ranges reflect Pleistocene climates linked to the Last Glacial Maximum.

Climate and hydrology

Climatically the plateau exhibits continental aridity with large diurnal and seasonal temperature ranges, influenced by the Siberian High and the East Asian Monsoon. Precipitation gradients run from scarce in the southern Gobi to more abundant in the northern steppe and mountain zones, affecting the regimes of rivers such as the Onon River and the Buyant River. Permafrost, as found in regions bordering Sakha Republic, and seasonal snowpack influence groundwater recharge and lacustrine systems like Lake Khövsgöl and Uvs Lake. Droughts and dust storms have intersected with atmospheric phenomena such as El Niño–Southern Oscillation and regional teleconnections observed in climatology studies at institutes like the Institute of Geography, Mongolian Academy of Sciences.

Ecology and biodiversity

Vegetation types include temperate grassland dominated by species found on the Eurasian Steppe, semi-desert shrublands, and montane coniferous forests similar to those of the Sayan Mountains. Faunal assemblages historically included keystone species such as the Przewalski's horse, saiga antelope, Mongolian gazelle, and predators like the snow leopard and the grey wolf. Migratory birds use wetlands on the plateau as staging areas, connecting to flyways used by species cataloged by organizations such as the Wildlife Conservation Society and the RSPB. Endemic plant taxa and relict populations persist in isolated ranges, while invasive species and overgrazing have altered community structure studied by researchers at the Mongolian University of Life Sciences.

Human history and cultures

Human occupation includes Paleolithic sites linked to Upper Paleolithic cultures, Bronze Age societies such as the Xiongnu, and historic polities including the Xianbei and the Khitan. The plateau was central to the rise of the Mongol Empire under Genghis Khan and later nomadic confederations like the Oirats. Pastoralist lifeways centered on horse culture and yurts (ger), with trade contacts along branches of the Silk Road connecting to Tang dynasty, Yuan dynasty, and Ming dynasty polities. During the 20th century, the region experienced transformations under Republic of China (1912–1949), the People's Republic of China, and the Mongolian People's Republic, with legacies visible in urban centers, archaeological sites like Karakorum, and cultural institutions including the National Museum of Mongolia.

Economy and land use

Traditional pastoralism—herding sheep, goats, cattle, yaks, camels, and horses—remains central alongside mining of resources such as coal, copper, and rare earths exploited by corporations like Erdenes Tavan Tolgoi and China National Mining Group. Agricultural activity occurs in irrigated valleys along rivers such as the Ider River and around oases that link to trade routes to Beijing and Irkutsk. Infrastructure projects like transcontinental railways and energy corridors connect mineral regions to ports and processing centers in Dalian and Tianjin. Tourism focused on sites such as Gorkhi-Terelj National Park, equestrian festivals, and cultural heritage attracts operators from UNESCO-listed networks and private tour companies.

Conservation and environmental issues

Conservation challenges include desertification of the Gobi, overgrazing-driven degradation of steppe, water scarcity affecting transboundary basins like the Selenge–Enisei system, and biodiversity loss impacting species protected under conventions such as the Convention on Biological Diversity. Cross-border initiatives involve institutions like the World Bank, Asian Development Bank, and bilateral agreements between Mongolia and China addressing grazing management, protected-area networks (e.g., Uvs Nuur Basin World Heritage Site), and restoration programs modeled after work by NGOs including WWF and the Nature Conservancy. Climate-change projections by agencies such as the Intergovernmental Panel on Climate Change emphasize warming and altered precipitation, complicating efforts to balance development driven by corporations and state agencies with conservation enforced through national laws and international partnerships.
