摘要
采用样地、样线调查法,对湖北长阳崩尖子自然保护区的珍稀濒危保护植物的资源状况和分布特征进行了研究,并运用濒危系数、遗传价值系数和物种价值系数对其优先保护顺序进行定量分析。结果表明:(1)保护区内共有珍稀濒危保护植物38种,隶属于29科35属;(2)经优先保护评价排序,其中属于一级优先保护的物种有4种,二级优先保护有19种,三级优先保护有13种,四级优先保护有2种;(3)自然保护区内海拔1 800 m以下区域分布的珍稀濒危保护植物种类较多,所占比例较大。
Based on sample-plot survey and sample-line survey, the resource status and distribution characteristicsof rare and endangered plants in Bengjianzi Nature Reserve was studies, and the conservation priority of these keyplants were also analyzed by using endangered coefficient, genetic value coefficient and the specific value coeffi-cient. The results showed that: (1) There were 38 species of rare and endangered plants belonging to 35 generaof 29 families; (2) 4 species was ranked as the first grade for conservation priority, 19 species as the secondgrade, 13 species as the third grade, and 2 species as the fourth grade; (3) Most rare and endangered specieswere distributed below 1 800 m of the nature reserve.
