首次报道了贵州普安县泥堡村韭菜烂滩的卡林型金矿区和非金矿区的苔藓.记录了泥堡韭菜烂滩卡林型金矿生苔藓3科8属15种,非金矿生苔藓9科15属20种.通过比较我们得到韭菜烂滩卡林型金矿区和泥堡非金矿区苔藓的相似性系数为11.4%.这表明这两个生境下的苔藓组成差异极大.在这个地区有13种苔藓植物(包括异芽丝瓜藓Pohlia leucostoma、卵蒴丝瓜藓P.proligera、长蒴藓Trematodon longicollis等)只生长在卡林型金矿上,这表明有一些苔藓植物适应卡林型金矿这种基质.也许,在泥堡地区某些苔藓植物的分布与卡林型金矿存在一定的关系.%In this paper,the bryophytes both on Carlin gold mine and non-gold field area of Jiueailantan in Nipu Vil-rn lage of Pu'an County in Guizhou Province were reported for the first time. 15 speciea belonging to 8 genera of 3 fami-rn lies were found on the Carlin gold mine of Jiucailantan, and 20 species belonging to 15 genera of 9 families on non-goldrn field area in Nipu. Through comparison, the similarity coefficient of species level was 11.4% between the two samplern sites in Nipu. It showed the distinct diversity on bryophytes of Carlin gold mine and non-gold field area. Among thesern bryophytes, 13 species of them (Pohlia leucostoma, P. proligera, Trematodon longicollis, etc. ) only grew on Carlinrn gold mine, indicating that some bryophytes adapted to the substrate of Carlin gold mine, and there were some relationsrn between bryophytes and Carlin gold mine distribution in Nipu area.
