摘  要：
通过对赣东北珍稀濒危树种珍稀濒危树种的资源量、分布位置数、吸引度、保护指数、接近度、生境条件变异、栽培利用状况、珍稀濒危保护级别等8个指标进行评价,得出珍稀濒危指数,依据指数的大小来确定受威胁状况和优先保护次序。结果表明:此次调查的赣东北的珍稀濒危树种共53科97属159种,其中一类优先保护珍稀濒危树种有43科63属80种,受威胁程度最高,代表树种为水松(Glyptostrobus pensilis)、杜仲(Eucommia ulmoides)、天女木兰(Magnolia sieboldii)、永瓣藤(Monimopetalum chinense)等;二类优先保护珍稀濒危树种共31科50属79种,受威胁程度较高,在利用的同时应合理保护,主要代表种有大叶青冈(Cyclobalanopsis jenseniana)、长序榆(Ulmus elongata)、浙江红山茶(Camellia chekiangoleosa)等;调查发现赣东北无资源受威胁的三类优先保护珍稀濒危树种,说明赣东北的珍稀濒危树种资源受威胁程度均较高,应加强保护。此次调查对赣东北的珍稀濒危树种情况有了较深入的了解,可为相关部门对树种的科学开发利用与保护提供数据基础与理论指导。

摘  要：
Eight indexes of the rare and endangered tree species were evaluated in northeastern Jiangxi province, such as distribution sites, attraction degree, protection index, approach degree, habitat conditions variation, cultivation status, protection grade. Rare and endangered index was got, according to economic stress index form a protected resources sequence from high to low, and the higher economic stress index, the priority of conservation. The results showed that: there are 53 families 97 genus 159 species of rare and endangered trees in northeastern Jiangxi province, and 43 families 63 genus 80 species of trees should be the most priority of conservation, such as Glyptostrobus pensilis, Eucommia ulmoides, Magnolia sieboldii, Monimopetalum chinense and so on. 31 families 50 genus 79 species of trees should be more priority of conservation, such as Cyclobalanopsis jenseniana, Ulmus elongata, Camellia chekiangoleosa and so on, which indicated that the. resources of rare and endangered species in northeast Jiangxi were under high threat and should be protected. The research in this paper which could provide reference for sustainable use and conservation.
