摘要

摘要: 于2013-2015年对湖北星斗山国家级自然保护区进行多次全面野外调查，采集植物标本3441号，并对其种子植物区系特点进行了研究。结果显示，该保护区共有野生种子植物138科678属1617种，其中裸子植物6科15属19种，被子植物132科663属1598种。区系分析表明，热带科（66.06%）多于温带科（33.94%），这与该区曾经历过古热带的历史背景相吻合；属级水平上则为温带属性（58.45%）强于热带（41.55%）；中国特有种623个（占总种数的38.53%），均与四周区域所共有，反映出东西南北植物区系在此交汇渗透的态势；这些均表明该区种子植物区系成分不但复杂多样，而且还具有过渡区域的特点；保护区内植物区系还具有古老、残遗的特性，一些古老的残遗植物在该地有良好的原生群落分布；保护区内特有树种和珍稀濒危植物也很丰富，具有很大的保护价值。

Abstract: Based on comprehensive field surveys undertaken in Xingdoushan Nature Reserve, Hubei Province, from 2013 to 2015, resulting in 3441 plant specimens, we analyzed the floristic features of seed plants in Xingdoushan. A total of 1617 species belonging to 678 genera and 138 families were found, which consisted of 19 gymnosperms (15 genera and 6 families) and 1598 angiosperms (663 genera and 132 families). Our results showed that there were more tropical plant families (66.06%) than temperate ones (33.94%), consistent with the historical context that this area once experienced ancient tropical flora. However, there were more temperate plant genera (58.45%) than tropical ones (41.55%). In addition, 623 endemic species (38.53% of total plants) were found, which were also located in the surrounding areas, reflecting east-west intersection trends. The floristic elements of the seed plants in Xingdoushan were not only complex and varied, but also exhibited transition zone distribution. Ancient relic features were also found, with certain plants showing good native community distribution. There were a considerable number of endemic, rare, and endangered plants, which exhibited important protection value.
