In order to further grasp the present situation of plant resources of Bailixia provincial nature reserve in Sichuan ,the plant resources of nature reserve w ere investigated . The results showed that ,there were 1 429 species of wild vascular plants belonging to 682 genera and 150 families in nature reserve ,among them ,there are 74 species pteridophyte belonging to 44 genus and 22 families ,24 species gymnosperm belonging to 17 genus and 8 families ,1 319 species angiosperm belonging to 625 genus and 120 families .T he quantity of vascular plants families account for 64.66% of Sichuan ,w hich account for 41.21% of China . The quantity of vascular plants genera account for 42.32% of Sichuan ,which account for 20.20% of China .The quantity of vascular plants species account for 15.32% of Sichuan , w hich account for 4.88% of China .T here are 7 kinds of national first class protected plants and 13 kinds of national second class protected plants in nature reserve ,in addition , T huj a sutchnenensis which is now listed as a critically endangered species in the world was found . The seed plant flora consists of 15 areal‐types and 18 sub‐types .The flora of seed plant showed an obvious feature of temperate ,tropical elements also accounted for a certain proportion ,which has the transition characteristics from temperate to tropic .The flora are of antiquity to some extentand . The vegetation of the nature reserve is divided into 3 vegetation type groups ,8 vegetation types and 24 formations .
