摘要
在对广西天峨红水河龙滩库区植被调查研究的基础上,论述了该地区植物多样性.结果表明:该地区计有土著维管束植物182科、665属、1 230种,其中裸子植物4科、5属、9种,被子植物155科、603属、1 145种;地带性植被为含季雨林成分的季风常绿阔叶林;库区植物区系具有丰富性、古老性、复杂性和过渡性等特点,且有相当多的中国特有分布的类群,其中有20个特有属、693个特有种(占该区种子植物总数的60.02%),珍稀保护植物13种集中于此,是中国植物生物多样性最关键的地区之一.
The vegetation and plant biodiversity of Longtan Reservoir Area （Guangxi Tian-e） were surveyed. Based on the statistics from the lists of indigenousvascular plants, there are 1230 species, belonging to 182 families and 655 genera, among which are gymnosperm： 9 species, 5 genera and 4 families, and angiosperm.. 1145 species, 603 genera and 155 families. The vegetation in this area is zonal, belonging to the monsoon evergreen broad-leaved forest with elements of seasonal rain forest. A statistical analysis indicates that the flora of Longtan Reservoir Area has characteristics of richness, ancientness, complicatedness and transition. This area possesses a considerable amount of endemic elements, among which there are 20 genera, 693（60.02%） species and 13 species of rare protected plants. The area is one of the key regions to prove China＇s plant biodiversity. Key words.. Hongshuihe River; Longtan Reservoir Area （Guangxi Tian-e）; plant biodiversity; characteristics.
