Based on investigation for seven years,the vascular plant resource in Changbai Mountains are studied in the present paper. 47 forms, 190 varieties, 1 800 species belong to 629 genera and 143 families, which accounted for 5.80 %, 18.46 % and 47.67 % of the respective species, genera and families of total vascular plants in China. There are 25 rare and endangered species plants,which accounted for 1.39% in Changbai Mountains. 1 251 species of perennial herbs account for 69.5% of the vascular plants in Changbai Mountain. In this area, 51.56% of plant total can be used for medicines; 44.78% for ornamentals; 33.67% are for feed. 87.28% of species are distributed in Red Pine breadleaved-conifereus mixed forests zone at the altitude 450 - 1 000 m. The concrete suggestions of protection and exploitation are given.
