Abstract: Based on the field investigation and botany taxonomy method, the eco-geographic distribution of rare and endangered plants and endemisc plants in Karakorum Mountains of China were studied. The results indicate that: there are 34 species of rare and endangered plants in Karakorum Mountains belonging to 18 genera and 15 families, among which 16 species are national key protected plants, 18 species are key protected plants in Xinjiang. There are 32 endemic species in Karakorum Mountains belonging to 24 genera and 12 families, among which 30 species are endemic species in Xinjiang, two species are endemic species in Tibet. The distributions of three endemic species in Xinjiang have spread to Tibet, which are Lepidium kunlunshanicum G. L. Zhou et Z. X. An, Poa spiciformis D. F. Cui and Androsace flavescens Maxim. The distribution area of three endemic species in Xinjiang has decreased, which are Salix metaglauca C. Y. Yang, Sabina centrasiatica Kom and Arenaria aksayqingensis L. H. Zhou. The horizontal distribution of rare and endangered species and endemic species decreases from the northwest to the southeast, and the vertical distribution concentrates at the altitude of 3 000-4 500 m where perennial herb are the main species with a few shrubs and trees.

Key words: eco-geographic distribution, endemic species, Karakorum Mountains of China, rare and endangered plants
