| 摘 要： | 柳州市龙潭—都乐公园植物区系是广西中部一个被破坏后经多年保护恢复起来的岩溶石山植物区系。总面积9平方公里,共有维管束植物152科455属675种。由于处于中亚热带向南亚热带过渡的气候带上,气候温和,阳光充足,雨量充沛,植物的地理成分复杂,但以亚热带和热带成分占优势;特有种、属少,但岩溶成分较明显;由于岩溶生态条件影响,与(?)岗植物区系相比,属的相似性比率略高于与大瑶山植物区系的比率。按吴征镒教授对中国植物区系的划分,它应属于泛北极植物区、中国—日本森林植物亚区、滇黔桂地区的一个小区。

| Abstract: | This article deals with the floristic features of Longtan-Dule park and the retationship with adjacent floras. Longtan-Dule Park stands in the transition zone of the south-subtropics and middle-subtropics, the area is 9 km~2 in total. The flora includes 675 species of vascular plants, belonging to 152 families and 455 genera, of which 19 species belong to Gymnosperms (all cultivated) and 610 species to Angiosperms.This flora is a limestone flora with complex geographical elements, but the subtropical and tropical elements predominate, influenced by the karst topography the limestone species are distiact, the index of similarity for the genera between Logtan-Dule and Longgang is more than Longtan-Dule and Dayaoshan. The flora should belong to Holarctic kingdom, Sino-Japan forest subkingdom, YunnanGuizhou-Guangxi region, according to Pr. Wu Chengyih. |
