摘要
报道了南岭国家级自然保护区种子植物区系的组成与特点调查结果表明，该区系的种类丰富，计有种子植物１７５科８２２属２２９２种，其中裸子植物９科２０属３０种，被子植物１６６科８０２属２２６２种区系的地理成分复杂，具有中国１５个种子植物属分布区类型中的１４个，与世界其它地区的植物成分均有一定联系，其中热带成分占明显优势，同时也受到温带成分较强烈的影响；有３３个中国特有分布属本区系具有源远流长的发生发展历史，既有相当数量的原始古老类群，也有发育较为丰富完整的现代进化类群，表明南岭山脉及其邻近地域有可能是某些种子植物类群的起源地。
Floristic characteristics of the seed plants of Nanling National Nature Reserve were studied. A total of 2 292 species and varieties of the seed plants belonging to 822 genera, 175 families, was identified in Nanling National Nature Reserve. Among them, there are 30 species belonging to 20 genera, 9 families are of gymnosperm and 2 262 species and varieties belonging to 802 genera, 166 families are of angiosperm. The distribution elements of Nanling's flora are complex, diverse and widely related to many parts of the world. They comprise 14 of 15 distribution types of Chinese seed plants.The flora is predominated by tropical and subtropical elements and also strongly affected by temperate elements. There are 33 endemic genera. Nanling's flora has a long biological history. On the one hand, there are many primitive and relic plants, Nanling might be one of their original centers;on the other hand there are also many advanced plants, Nanling might be one of their specialization and distribution centers.
