摘要
通过对九峰山自然保护区不同海拔苔藓植物标本的采集和鉴定,分析了九峰山苔藓植物的种类组成、α多样性指数、β多样性指数及均匀度指数。结果表明:九峰山自然保护区苔藓植物共有221种,其中苔类植物包含19种,藓类植物包含202种,共计37科91属221种;九峰山不同海拔苔藓植物的ShannonWiener指数(H值)变化明显,海拔2200m的H值最高,表明物种种类最多,丰富度最大;海拔1600m和2200m间的βC多样性指数最大,苔藓植物物种的变化速率是最快的,且其物种的更替也非常剧烈;海拔1400m和海拔2200m的βT指数值最大的,揭示出两地苔藓植物的群落变化是最明显的。
Based on the bryophytes＇ samples collected and tested at different altitude from Jiufeng Mountain Natural Protection Area, this paperanalyzed the species composition, αdiversity index, βdiversity index and evenness index. The result showed that there are 37 families, 91 genuses and 221 species of bryophytes in total, including 19 species of hepaticae and 202 species of mosses. Shannon-Wiener Index （H value） of Bryophytes in Jiufeng Mountain varies greatly from altitude to altitude, with the highest H value in 2200m indicating that the species had the largest species and the richness was the highest. In addition, βC diversity index reaches its peak at the altitude of 1600m and 2200m, where the rate of change of bryophyte species is the fastest, and the change of species is very intense. The maximum of βT index appears at the altitude of 1400m and 2200m, showing the most obvious change of species of bryophytes in these two altitudes.
