摘　　要：【目的】本研究旨在系统分析浏阳市的野生种子植物资源,为该地区野生种子植物的多样性评估、资源利用及保护工作提供科学依据。【方法】通过综合野外深入调查和文献研究,对浏阳市野生种子植物的物种组成、区系特性及其特有现象进行了深入分析。【结果】浏阳市记录了野生种子植物共计167科664属1513种(含种下分类单元),其中裸子植物5科6属8种,被子植物162科658属1505种。物种多样性分析显示,167科可分为10个分布区类型,664属可划分为13个分布区类型和19个变型。此外,浏阳市拥有18个中国特有属和453个中国特有种。【结论】浏阳市的野生种子植物区系表现出高度的多样性和明显的区系优势,单种属和寡种属是其区系的主要成分。区系分析表明,浏阳市野生种子区系具有亚热带特征和显著的过渡性质,同时特有程度较高。这表明该地区拥有丰富的特有物种资源,对生物多样性保护具有重要意义。【Objective】This study aims to systematically analyze the wild seed plant resources of L iuyang City,providing a scientific basis for the diversity assessment,resource utilization,and conservation efforts of wild seed plants in the area.【Method】Through comprehensive field investigations and literature research,an in-depth analysis was conducted on the species composition,regional characteristics,and endemic phenomena of wild seed plants in Liuyang City.【Result】A total of 167 families,664 genera,and 1513 species(including infraspecific taxa)of wild seed plants were recorded in Liuyang City,of which there were 5 families,6 genera,and 8 species of gymnosperms,and 162 families,658 genera,and 1505 species of angiosperms.The analysis of species diversity revealed that the 167 families could be categorized into 10 distribution patterns,and the 664 genera could be divided into 13 distribution area types and 19 variants.Furthermore,Liuyang City was the home to 18 endemic genera and 453 endemic species of China.【Conclusion】The flora of wild seed plants in Liuyang City exhibits a high degree of diversity and distinct regional advantages,with monotypic and oligotypic genera being the main components of its regional flora.The regional analysis shows that the wild seed flora of Liuyang City has subtropical characteristics and a significant transitional nature,while also having a high degree of endemism.This indicates that the area possesses a rich resource of endemic species,which is of great importance for the conservation of biodiversity.
