| Abstract: | By adopting the evaluation index system of conservation priority which included threatened coefficient,genetic coefficient,utilization coefficient, protection status coefficient and list status coefficient,the endangered plants in Northeast China were quantitatively analyzed and synthetically evaluated,and the value of conservation priority and conservation priority grades of the endangered plants were determined.The results showed that there were 60 species of endangered plants belonging to 42 genera and 25 families in Northeast China,the value of conservation priority ranged from 0.853 8-0.318 4.The endangered plants were divided into 3 grades according to their values of conservation priority, 17 species belonging to 15 genera and 11 families were in the first grade protection,18 species belonging to 14 genera and 11 families were in the second grade protection,25 species belonging to 17 genera and 13 families were in the third grade protection.The quantitatively evaluation index system of conservation priority in this paper represented the degree of conservation priority of the endangered plants comprehensively,objectively and accurately. |
