摘  要:
Based on sample-plot survey and sample-line survey,the resource status and distribution characteristics of rare and endangered plants in Bengjianzi Nature Reserve was studies,and the conservation priority of these key plants were also analyzed by using endangered coefficient,genetic value coefficient and the specific value coefficient. The results showed that:( 1) There were 38 species of rare and endangered plants belonging to 35 genera of 29 families;( 2) 4 species was ranked as the first grade for conservation priority,19 species as the second grade,13 species as the third grade,and 2 species as the fourth grade;( 3) Most rare and endangered species were distributed below 1 800 m of the nature reserve.
