摘要: 青藏高原高寒荒漠地带位于高原主体西北部地势最高的部分。该区域气候极其寒冷干燥,属于高原亚寒带,高山高原地貌多被横向断陷盆地所切割;多年冻土发育,冰缘作用普遍;自然过程年青,高山寒漠土壤浅薄;生物区系成分交错,高寒荒漠景观突出;生态环境脆弱,需加大自然保护建设与管理。高寒荒漠地带腹地为寒冷干旱核心区域,是全球高原高山区域,具有独特地位的地生态格局。

Abstract: The high cold desert zone, located on the northwestern region, is the highest part of the Tibetan Plateau. This region with extremely cold and arid climate belongs to plateau subcold zone, which is characterized with high mountains and plateau landforms tranversed by lake basins, widespread permafrost and periglacial process, young natural process with shallow cold desert soil, and landscape of high cold desert with interfused composition of biota. Due to the vulnerable eco environment, construction and administration of natural conservation should be strengthened in this region. The cold arid core, existed in the hinterland of high cold desert zone, is a unique geo eco feature in the plateau and alpine region on the Earth.

Key words:  Tibetan Plateau, high cold desert zone, high, cold arid core area, structure, type of altitudinal belt, construction and administration of natural conservation
