摘要:  为制定江西庐山国家级自然保护区珍稀濒危植物的保护策略,采用濒危系数、遗传系数及物种价值系数等评价指标对58种珍稀植物的濒危程度和优先保护顺序进行评估。结果表明,自然保护区珍稀植物的综合评价值(VS)为0.153~0.742,濒危等级为安全的11种,占该区珍稀保护植物总数的19%;稀有的28种(48%);渐危的18种(31%);濒危的1种(2%)。优先保护顺序为I级的8种,占该区珍稀保护植物总数的14%,急需保护;Ⅱ级的22种(38%),需要保护;Ⅲ级的23种(40%),可以一般保护;IV级的5种(8%),较为安全。生境破坏和人为干扰是该区珍稀植物保护面临的主要威胁。

Abstract:  In order to make protection strategies of rare and endangered plants in Lushan National Nature Reserve, the endangered grade and conservation priority of 58 rare and endangered species were evaluated with indexes, such as endangered coefficient, genetic coefficient and species value coefficient. The results showed that the comprehensive evaluation value (VS) of rare and endangered plants in Lushan Nature Reserve ranged from 0.153 to 0.742. There were 11 species with safe grade, accounting for 19% of the total of rare and endangered plants in this area; 28 species fall into rare species for 48%; 18 species for 31% were listed in vulnerable species; and the endangered species had 1 species for 2%. Among those, 8 species were assessed as the first conservation class, accounting for 14% of the total of rare and endangered species, and 22, 23 and 5 species belong to the second, the third and the fourth conservation class, accounting for 38%, 40% and 8%, respectively, there were not rare and endangered species. So, it was concluded that the habitat destruction and human disturbance were the main threats to rare and endangered plants of the region.
Key words:  Rare and endangered plant  Endangered grade  Plant protection  Lushan National Nature Reserve
