安徽鹞落坪森林群落优先保护评价体系

在对鹞落坪国家级自然保护区的植物物种、群落进行调查的基础上,进行保护评价和多样性分析。结果表明：共记录物种145科786种;通过濒危评价,得出鹞落坪植物极危种有6种,濒危种15种,易危种41种,近危种66种,安全种658种;通过物种优先保护级别划分,一级保护2种,二级保护11种,三级保护21种,四级保护752种;通过对鹞落坪国家级自然保护区的17种典型森林群落进行累计确限度排序,得出青冈栎Cyclobalanopsis glauca群落、江南桤木Alnus trabeculosa群落有最高的优先保护值,而檫木Sassafras tzumu群落、黄山栎Quercus stewardii群落有最低的优先保护值。

Evaluation system of conservation priority of forest communities in Yaoluoping of Anhui Province

Plant diversity of forest communities in Yaoluoping National Nature Reserve was analyzed and the conservation was valued based on the field investigation. There were 786 species of plants which belonged to 145 families. The results of the evaluation of the endangered hierarchy indicated that there were six critically endangered speeies, 15 endangered species, 41 vulnerable speeies, 66 lower risky species and 658 secured species. Based on the conservation priority of species, there were four classes of plants under conservation. Two species were under class-one 21 species under class-three conservation, and 752 fidelity of 17 key communities was calculated and conservation, 11 species under class-two conservation, species under class-four conservation. The accumulative sequenced. The order of conservation priority for these communities was Com. Cyclobalanopsis glauca 〉Com. Alnus trabeculosa 〉Com. Sassafras tzumu 〉Com. Quercus stewardii.
