摘要
通过对湖南衡山萱洲国家湿地公园种子植物资源详细调查,对其科、属组成及分布区类型、区系特征进行了统计分析。结果表明:该湿地公园共有土著种子植物130科、467属、750种,其中湿地植物有59科、164属、241种。通过对该湿地公园种植植物130科的分析,表明该区域热带性成分较强,与本区系所处的中亚热带向南亚热带过渡的环境条件相符合。通过对种子植物467属的特征分析,热带性分布属稍强于温带性属,反应了该湿地公园植物区系中亚热带性质。
On the basis of detailed investigation of floristic characteristics study on seed plants of Hengshan Xuanzhou Nationa Wetland Park in Hunan Province,the statistical analysis on family,genus composition,area type and floristic characteristics of its seed plants were analyzed.The results indicates as follows:there are 130 families、467 genera and 750 species of indigenous seed plants in the wetland park,of which there are 59 families,164 genera and 241 species of wetland plant.Based on the analysis of 130 families of seed plants in the wetland park,it is shown that the tropical composition of the region is strong,which is consistent with the environmental conditions of the transition from the subtropical to the sub-tropical in which the region is located.Based on the analysis of characteristics of 467 genera of seed plant,the tropical distribution genus is slightly stronger than the temperate genus,which also reflects the subtropical nature of seed plants of the wetland park.
