THE FLORISTIC GEOGRAPHY OF NANLING MOUNTAIN RANGE,CHINA──Ⅲ.Florogeographic Affinities and Floristic Division

南岭山地与相邻地区植物区系具有明显的过渡或替代关系，主要通过亚热带及亚热带亚热带亚洲分布成分与华南南亚热带及亚洲热带地区联系；与华中和华东地区植物区系的联系以亚热带及亚热带至温带分布和中国—日本间断分布成分来沟通；与西南地区植物区系的联系则表现为两地共有的古老和与遗成分区及石灰岩山地区系成分．华夏植物区系，是从古老的华夏植物群逐步发展起来的统一体，在区系分区上应划归为统一的华夏植物界，下分东亚植物区、马来西亚植物区和印度—喜马拉雅植物区。南岭山地植物区系拥有其自身的标志种、特有属和丰富的特有种，在区系分区上可划为完整的南岭植物亚省，下分东南岭植物县、中南岭植物县和西南岭植物县。

Nanling Mountain Range has close relationships of floristic transition and vicariance to the adjacent regions.Its flora is closely related to that of south subtropical China and tropical Asia by mainly the subtropical to tropical elements,and to that of Central and East China by the elements of subtropical China,subtropical to temperate elements and Sino-Japan disjuncted elements,and to that of Southwest China by some archaic and relic elements and elements on limestone. Studies indicate that the flora of Naming Mountain Range possesses many indicative species and rich endemic species and genera, and should be included in the Naming Sub-province,including East Naming District,Central Naming District and West Naling District,which belongs to Southern Chinese Province, Eastern Asiatic Region,Cathaysian hingdom.
