The Research on the Sequences of Preferential Protection of the Rare andEndangered Plants in Changbai Mountains

This paper dealed with 85 families,199 genuera,270 species,25 varieties and 3 formes of rare and endangered plants investigated in Changbai Mountains from 1993 to 2005.The"coefficient of endangerment" and the"value of superior conservation"were obtained through index quantification and weight allocation,thus the degree of endangerment and the sequences of protection priority were determined.They could offer a first-hand primitive materials for the domestic and foreign experts who studied the rare and endangered plants in Chanbai Mountains and for some relevant departments who formulated the concrete protection measures.
