摘　　要：泥炭藓是贫营养泥炭中重要的成碳植物,也是花卉、园艺领域主要的栽培基质,具有重要的生态价值及经济价值。为高效地保护及利用泥炭藓,本文系统地整理了研究组现有泥炭藓科植物标本,并对泥炭藓科植物在贵州省主要分布区域黔南州、娘娘山国家湿地公园、麻江县老蛇冲自然保护区等地进行了补充调查。结果显示:贵州省现有25种泥炭藓原生种(含种以下分类单位),占全国总种数的52.08%,生境类型多样,包括高山泥炭藓沼泽、草本-泥炭藓沼泽、木本-泥炭藓沼泽以及潮湿林下等多种类型。垂直分布特点为随着海拔升高,泥炭藓种数先逐渐增加后减少,在海拔1300~1700 m时,泥炭藓资源最丰富;在水平分布上,贵州省44个市(县)有泥炭藓分布,其中分布最多的县是铜仁市的江口县,共16种,占全省泥炭藓科植物总种数的64%。Sphagnum mosses is an important carbonaceous plant in oligotrophic peatland and plays a key role in maintaining the structure and function of peatland.At the same time,Sphagnum mosses hasbeen widely used as a cultivation substrate in the fields of flowers and horticulture,so it has great economic value.In this paper,the plants of Sphagnum L.of Sphagnaceae in Guizhou were systematically investigated and counted.The results showed that there were 25 native species(including subspecies classification units)of Sphagnum mosses in Guizhou Province,accounting for 52.08%of the total species in China.Its habitat types include alpine-Sphagnum swamp,herb-Sphagnum swamp,woody-Sphagnum swamp and moist forest environment.In the vertical distribution,the number of species increased gradually and then decreased with the increase of altitude and peat moss resources are the most abundantat 1300-1700 m a.s.l..In terms of horizontal distribution,there are 44 counties with Sphagnum mosses distribution in Guizhou Province,of which the most distributed counties are Jiangkou County,Tongren City,with 16 species,accounting for 64%of the total number of the province.
