    摘要:

    通过对安徽大别山区种子植物资料收集和实地勘察,在此基础上得到了安徽大别山区种子植物区系的特征和珍稀濒危保护种子植物的分布,并与周边山区进行了对比分析。结果表明:(1)安徽大别山区种子植物种类繁多、类型丰富,区域内种子植物共计145科,731属,1 648种(不含种以下分类)。(2)通过统计和PCA方法分析,表明安徽大别山区植物区系整体上呈现亚热带向温带过渡的性质。(3)安徽大别山区与岳西古井园种相似性系数最高(64.52%),与清凉峰次之(40.22%),与舒城万佛山最低(24.65%)。(4)安徽大别山区内含21种珍稀濒危保护种子植物,包括5种濒危植物、2种国家一级保护植物和14种国家二级保护植物。

    Abstract:

    Based on the documents collection and the field investigation, this study concentrates on the floristic characteristic of seed plant and the distribution of rare and protected seed plants in Dabie Mountain of Anhui Province, and we also compared Dabie Mountain of Anhui Province with the around districts. The results showed that: (1) The resources of seed plants are rich in Dabie Mountain of Anhui Province. This area contains 1 648 species (excluding subspecies) of seed plant species, which belong to 145 families and 731 genera. (2) By using statistical and the principal component analysis, the flora is geographically a transitional area from subtropical to the temperate types. (3) The coefficient similarity of species between Dabie Mountain in Anhui Province and Gujingyuan in Yuxi(64.52%) has a close relationship, and Qingliangfeng(40.22%) has a weekly relationship, and Wanfoshan in Shucheng(24.65%) has a distant relationship; (4) There are 21 rare and protected seed plants, including 5 kinds of rare and endangered plants, 2 kinds of firstclass state protected plants and 14 kinds of secondclass state protected plants.
