Ecoregions of China China spans vast latitudinal and longitudinal ranges, encompassing ecoregions that include temperate Manchuria forests, subtropical Yunnan rainforests, alpine zones of the Tibetan Plateau, and arid belts of the Gobi Desert and Taklamakan Desert. These areas intersect with major geographic features such as the Himalayas, Kunlun Mountains, Sichuan Basin, and the North China Plain, and are shaped by influences from the Pacific Ocean, Indian Ocean, and continental interior air masses affecting Beijing, Shanghai, Guangzhou, and Chengdu.

Overview

China's ecoregions are categorized by international schemes used by organizations including the World Wildlife Fund, the International Union for Conservation of Nature, and the Convention on Biological Diversity, and are components of larger realms such as the Palearctic and Indomalayan regions. Climatic drivers including the East Asian Monsoon, the Indian Monsoon, and rainshadow effects from the Himalaya create gradients from tropical montane forests near Hainan to cold deserts bordering Mongolia and Russia. Major river basins—the Yangtze River, Yellow River, Pearl River, and Mekong River (Lancang)—structure freshwater ecoregions that connect to coastal seas like the Bohai Sea, Yellow Sea, and South China Sea.

Terrestrial Ecoregions

China's terrestrial ecoregions include boreal conifer forests in Heilongjiang linked to the Sikhote-Alin range, temperate broadleaf and mixed forests across the Loess Plateau and the Taishan-Dabie Mountains corridor, subtropical evergreen forests in Fujian and Guangxi, and tropical seasonal forests in southern Yunnan and Hainan. Montane ecoregions on the Tibetan Plateau and Hengduan Mountains host alpine meadows and shrublands that span from Qinghai to Sichuan and extend toward Bhutan and Nepal. Desert and xeric shrublands include the Taklamakan Desert within Xinjiang and the Gobi Desert along the Inner Mongolia border; temperate grasslands cover the Northeast China Plain and steppe margins adjoining Mongolia.

Freshwater and Marine Ecoregions

Freshwater ecoregions follow major hydrological systems: the Yangtze River basin supports floodplain lakes such as Poyang Lake and hosts endemic fishes linked to the Three Gorges landscape, while the Yellow River basin includes loess-fed tributaries and steppe headwaters in Shaanxi and Gansu. Transboundary river ecoregions include the Mekong River (Lancang) with headwaters in Tibet and downstream reaches through Myanmar, Laos, Thailand, Cambodia, and Vietnam. China’s marine ecoregions encompass coastal shelves and continental margins from the Bohai Sea and Yellow Sea—important for migratory birds along the East Asian–Australasian Flyway—to the warm waters of the South China Sea and island systems near Hainan.

Biodiversity and Endemism

China is a global center of endemism, containing refugia for lineages such as the giant panda in Wolong National Nature Reserve and Qinling populations, the Chinese alligator in the Yangtze lower basin, and endemic rhododendrons in the Hengduan Mountains. Biodiversity hotspots recognized under the Conservation International framework include Southeast China and Himalaya, hosting endemic mammals like the Tibetan antelope (chiru) and avifauna including Sichuan jay and Chinese monal. Floristic provinces intersect with historical biogeographic centers such as Yunnan and Guizhou, which harbor rich bryophyte, orchid, and magnolia lineages noted by botanists at institutions like the Chinese Academy of Sciences and the Royal Botanic Gardens, Kew in collaborative research.

Threats and Conservation Measures

Ecoregions across China face threats from land-use change driven by urban expansion in Shanghai and Guangzhou, agricultural conversion in the North China Plain, hydrological alteration from projects such as the Three Gorges Dam, deforestation in parts of Inner Mongolia and Yunnan, and pollution in coastal waters off Guangdong and the Yangtze River Delta. Conservation responses include creation of protected areas like Changbaishan Nature Reserve, species recovery programs for giant panda and Siberian tiger populations coordinated with agencies including the State Forestry and Grassland Administration and international partners like WWF and IUCN. Restoration initiatives such as the Grain for Green program, ecological redline policies overseen by the National Development and Reform Commission, and marine protected area expansion in the South China Sea aim to reduce habitat loss and support ecosystem services.

Research, Mapping, and Management Approaches

Scientific mapping of Chinese ecoregions integrates remote sensing from satellites operated by China National Space Administration and international platforms like Landsat and Sentinel with ground surveys by universities such as Peking University, Tsinghua University, and the Chinese Academy of Sciences. Conservation planning increasingly uses spatial tools from the United Nations Environment Programme World Conservation Monitoring Centre and approaches like systematic conservation planning tested across transboundary areas with Mongolia, Russia, and Vietnam. Adaptive management emphasizes community-based conservation in ethnic minority regions of Tibet and Yunnan, biodiversity offset frameworks piloted in provincial governments, and long-term ecological monitoring at networks including the Chinese Forest Biodiversity Monitoring Network.
