摘要:
为加强对新丰江库区内野生珍稀濒危木本植物保护, 研究基于新丰江库区内 9 块样地实地调查 数据, 利用濒危植物优先保护法和层次分析法, 对影响野生珍稀濒危木本植物优先保护的 10 个评价指标 进行计算, 结果表明: (1) 新丰江水库库区内共有野生木本植物 147 种, 隶属 53 科 84 属, 其中野生珍稀 濒危木本植物 7 种, 隶属 6 科 7 属; (2) 通过对 7 种野生珍稀濒危木本植物的濒危系数、 遗传价值系数、 物种价值系数共 10 个指标进行分析及综合评价值计算, 发现野生珍稀濒危木本植物的优先保护顺序为薄 叶红厚壳 Calophyllum membranaceum>小果柿 Diospyros vaccinioides>格木 Erythrophleum fordii>软荚红豆 Ormosia semicastrata>黏木 Ixonanthes reticulata>吊皮锥 Castanopsis kawakamii>观光木 Michelia odora, 其中 薄叶红厚壳、 观光木、 格木、 小果柿和软荚红豆为濒危种, 黏木和吊皮锥为渐危种; (3) 利用层次分析 法, 对 10 个指标进行综合权重计算, 发现野生珍稀濒危木本植物优先保护顺序为薄叶红厚壳>小果柿>软 荚红豆>格木>黏木>观光木>吊皮锥; (4) 根据优先保护等级, 薄叶红厚壳、 小果柿、 格木、 软荚红豆、 黏木、 吊皮锥和观光木 7 种野生珍稀濒危木本植物均属于Ⅰ级、 即最优先保护植物。

Abstract:
In order to strengthen the protection of wild rare and endangered woody plants in Xinfengjiang Reservoir area, based on the field survey data of 9 sample plots in Xinfengjiang Reservoir area, the paper calculated 10 evaluation indicators affecting the priority protection of wild rare and endangered woody plants by using the protection of endangered plants priority law and analytic hierarchy process, the results showed that: ( 1) There were 147 species of wild woody plants belonging to 53 families and 84 genera in Xinfengjiang Reservoir area, including 7 species of rare and endangered wild woody plants belonging to 6 families and 7 genera; (2) Through the analysis of 10 indexes of endangered coefficient, genetic value coefficient and species value coefficient of 7 wild rare and endangered woodyplants and the comprehensive evaluation value calculation, it was found that the priority conservation order of wild rare and endangered woody plants was Calophyllum membranaceum, Diospyros vaccinioides, Erythrophleum fordii, Ormosia semicastrata, Ixonanthes reticulata, Castanopsis kawakamii, Michelia odora, among them, C. membranaceum, M. odora, E. fordii, D. vaccinioides, O. semicastrata were endangered species, I. reticulata and C. kawakamii were gradually endangered species; (3) By using analytic hierarchy process (AHP), the comprehensive weight calculationof 10 indicators showed that the priority protection order of rare and endangered wild woody plants was C. membranaceum, D. vaccinioides, O. semicastrata, E. fordii, I. reticulata, M. odora, C. kawakamii; (4) According to the priority protection level, 7 wildrare and endangered woody plants, such as Calophyllum membranaceum, D. vaccinioides, E. fordii, O. semicastrata, I. reticulata, C. kawakamii, M. odora, belong to the highest priority protection plants of Class I.
Key words:  Xinfengjiang Reservoir area  rare and endangered wild woody plants  priority protection  comprehensive evaluation of value  analytic hierarchy process
