Abstract:: Investigated the forest trees of West Kunlun Mountains in Xinjiang by the field investigation and morphological taxonomy, the flora composition and features were analyzed.The results showed that the West Kunlun Mountains in Xinjiang was arid mountains，there were 17 families，25 genus，and 54 species including 6 kinds of new records in West Kunlun Mountains of Xinjiang.In the flora，the richness of genus was big，but had only few species，there were 1-3 genus in every family and few large families，only Salicaceae and Rosaceae was bigger families(5 generas 〖JP2〗and 16 species).While the single genus and minor-genus of families were both 11 families and as high as 64.71%，minor-species genera and single-species genera were up to 24 genus including 47 species，occupying 96.00% and 87.04% of the total number of generas and species separately in the region.They were a major component of plants of the genus and family and showed the natural conditions was very harsh and only 1 species of most families and genus distribute in this area.The species of forest trees was few，but most of them were establisher and dominance in this region，forming a obvious a single or composite community.Flofistic element with obvious temperate characteristics had 5 distribution types and 4 variants，having a certain link with the Mediterranea，West Asia and Central Asia area,while they were rare connection with Eest Asia.
