摘要
为研究峨眉山及周边山区珍稀濒危种子植物的多样性,项目组通过多年野外样线及样方调查,对该区域的珍稀濒危植物种类、珍稀濒危种子植物科、属的区系成分及特点进行调查和分析.结果表明:(1)峨眉山及周边山区共有185种珍稀濒危种子植物,归于36科98属;被子植物占绝对优势,有30科84属169种,裸子植物有6科14属16种.被《国家重点保护野生植物名录》收录的有78种,其中国家一级重点保护野生植物有8种;被《全国极小种群野生植物拯救保护工程规划》收录的有7种.(2)峨眉山及周边山区珍稀濒危种子植物的区系成分与该地区蕨类、裸子植物和被子植物的科、属地理分布区系成分基本一致,即温带成分和热带成分都比较丰富(温带成分略占优势),两种成分交汇融合,表现出热带、亚热带向温带过渡的特点.
Abstract
Based on field surveys for many years,this study analyzed the rare and endangered seed plants in Mount Emei,their composition,and characteristics of the flora.The results showed that:(1)There were 185 rare and endangered species belonging to 36 families and 98 genera in Mount Emei.Among them,there were 169 species,84 genera,and 30 families of angiosperms,and 16 species,14 genera,and 6 families of gymnosperms.78 species were included in the National Key Protected Wild Plant List.There were 8 species belonging to the first-grade.Seven species were included in the National Minimal Population Wild Plant Rescue and Protection Project Planning.(2)The flora elements of the rare and endangered plants were in agreement with the Ferns,Gymnosperms,and Angiosperms in Mount Emei.Both temperate and tropical-subtropical components were relatively abundant,with temperate componem slightly dominant,and they intersect and merge in Mount Emei area.
