以天宝岩国家级自然保护区为研究对象，研究4种不同类型泥炭沼泽群落生物量、物种多样性分布特征以及地上生物量与物种多样性间的关系.结果表明：泥炭藓群落( Comm. Sphagnum magellanicum)地上生物量和泥炭藓生物量均显著高于其他3类群落(P<0.05)，其他3类群落地上生物量和泥炭藓生物量无显著差异(P>0.05)，其中水竹-泥炭藓群落(Comm. Phyllostachys heteroclada-Sphagnum magellanicum)的地上生物量最低.不同泥炭沼泽类型群落物种多样性排序为垂穗石松+水竹-泥炭藓群落( Comm. Palhinhaea cernua+Phyllostachys heteroclada-Sphagnum magellanicum)>灯芯草-泥炭藓群落( Comm. Juncus effusu-Sphagnum magellanicum)>水竹-泥炭藓群落>泥炭藓群落.相关分析表明：天宝岩不同类型泥炭藓沼泽群落物种多样性与地上生物量关系不明显，基本无相关性(r≈0).亚热带泥炭藓沼泽湿地生物量主要由优势物种决定，而物种多样性则主要由非优势物种决定.长期水淹加上高寒气候造成资源环境空间异质性降低，“生态位互补”效应不明显.

Biomass of plant community,species diversity characteristics of each community and the relationship between aboveground biomass and species diversity among four different types of peat swamps were studied in Tianbaoyan National Nature Reserve. The results reveal that:the aboveground biomass of Sphagnum in community and biomass Sphagnum magellanicum were significantly higher than those of others ( P<0. 05 );and the aboveground biomass and biomass of Sphagnum among these three types of community were no significant difference (P >0. 05),while aboveground biomass of community Phyllostachys heteroclada-Sphagnum magellanicum was the lowest. Species diversity order among different types of peat swamp was as follows:community Palhinhaea cernua+Phyllostachys heteroclada-Sphagnum magellanicum >community Juncus effusu-Sphagnum magellanicum >commu-nity Phyllostachys heteroclada-Sphagnum magellanicum>community Sphagnum magellanicum. Correlation analysis showed that:relationship between species diversity and aboveground biomass of community among different types of Sphagnum mire in Tianbaoyan is not obvious,almost no correlation (r≈0),aboveground biomass of Sphagnum mire in subtropical zone were mainly determined by the dominant species, the species diversity was mainly decided by the non-dominant species, long-term flooding and cold weather caused spatial heterogeneity of resources and environment reduce,“Niche complementary” effect is not obvious.
