摘    要:通过对火灾后南瓮河草本沼泽湿地自然恢复5年的植物群落物种多样性与天然湿地进行对比,结果表明:火干扰湿地和天然湿地在物种丰富度上有差异,物种丰富度为13种和19种;物种丰富度的变化趋势同Shannon-Weiner指数、Pielou均匀度指数呈现正相关,同Simpson优势度指数呈现负相关;β多样性分析可知Sorensen指数为0.81,Jaccard指数为0.68;火干扰湿地和天然湿地的物种群落相似性较高,火干扰后植物群落自然恢复正向天然湿地演化。

关 键 词:湿地  火干扰  物种多样性  南瓮河湿地

Abstract:Species diversity of plant communities of Nanwenghe wetlands five years after fire and that of natural wetlands were compared.Result shows that:wetlands by fire disturbance and natural wetlands have significance in species richness,their species diversity being 13 & 19 species respectively;trend of species richness,which is positively correlated with Shannon-Weiner Index and Pielou Evenness Index,is positively correlated with Simpson Index;analysis of β diversity shows that:the Sorensen Index is 0.81 and Jaccard Index is 0.68.Community similarity of species for wetlands by fire disturbance and natural wetlands is more higher;species community of wetlands by fire disturbance naturally restore and are turning into natural wetlands.
Keywords:wetland  fire disturbance  species diversity  Nanwenghe wetlands
