Tibetan Plateau: A vast, high-elevation region of Central and East Asia, centered on Tibet and bounded by major mountain ranges. Hoh Xil occupies the plateau’s northern interior.
Hoh Xil National Nature Reserve: A protected area in Qinghai established to conserve the ecosystems and wildlife of the Hoh Xil region. Its protected landscapes encompass much of the region’s core wilderness.
UNESCO World Heritage Site: A place recognized under the UNESCO World Heritage Convention for outstanding cultural or natural value. The Hoh Xil natural area gained international recognition for its wilderness and ecological value.
Climate change on the Tibetan Plateau: The effects of long-term warming and changing precipitation on the Tibetan Plateau’s climate and ecosystems. Warming can alter Hoh Xil’s permafrost, water, and alpine habitats.
Kunlun Mountains: A major mountain range along the northern edge of the Tibetan Plateau. The range forms Hoh Xil’s northern boundary and shapes its terrain.
Qinghai–Tibet Railway: A railway connecting Xining in Qinghai with Lhasa in Tibet, crossing high-elevation terrain near Hoh Xil. Its route crosses the reserve and includes wildlife passages.
Tibetan antelope poaching: The illegal killing of Tibetan antelopes, historically driven by demand for their fine underfur. Poaching once sharply threatened antelopes migrating through Hoh Xil.
Permafrost degradation: The thawing and weakening of ground that was previously perennially frozen. Thaw could change Hoh Xil’s soils, wetlands, and infrastructure stability.
Alpine climate: A cold climate found at high elevations, with short growing seasons and conditions that vary with altitude. High elevation gives Hoh Xil severe winters and a brief growing season.
Tibetan antelope: A migratory antelope native to the Tibetan Plateau, also known as chiru. Hoh Xil provides habitat and migration routes for this emblematic species.
