摘要

摘要: 对贵州木油厂白云岩型汞矿6种生境中的苔藓植物进行分析研究。结果显示，(1)该汞矿共有12科37属85种(含变种、亚种)苔藓植物，其中以丛藓科、真藓科和青藓科为优势科，且适生于重金属污染的木油厂白云岩型汞矿区；(2)废石、废渣、矿洞、溪水是丛藓科、真藓科及青藓科共同分布的4种生境，此外，丛藓科和真藓科还见于废炉、真藓科和青藓科还见于树附生生境中；(3)废炉和废渣、废渣和溪水、废炉和溪水、废渣和矿洞、矿洞和溪水以及废炉和矿洞的苔藓植物的种相似性系数分别是0.49、0.46、0.45、0.41、0.35和0.31，表明它们各自均是两者亲近；矿洞和树附生、树附生和溪水的苔藓植物的种相似性系数均为0，说明彼此无关系；(4)区系地理成分含北温带分布(27.06%)、中国特有分布(24.71%)、东亚分布(17.65%)、热带亚洲分布(14.12%)、世界分布(7.06%)、泛热带分布(3.53% )、旧世界温带分布(2.35%)、热带亚洲至热带大洋洲分布(1.18%)、热带亚洲至热带非洲分布(1.18%)和温带亚洲分布(1.18%)10个分布类型；(5)生活型含矮丛集型(71.76%)、交织型(21.18%)、高丛集型(2.35%)、平铺型(2.35%)和一年生型(2.35%)5个类型。

Abstract: Bryoflores, collected from 6 habitats in dolomite type of Muyouchang Mercury Mine in Guizhou, China is analyzed in the paper. The results prove that (1) the bryophytes in dolomite type of Muyouchang Mercury Mine consists of 85 species, 37 genera, 12 families and the dominate families include Pottiaceae, Bryaceae and Brachytheciaceae. The bryophytes which belong to the three families are fit to g row in dolomite type of Muyouchang Mercury Mine; (2) Pottiaceae, Bryaceae and Br achytheciaceae distribute 4 common habitates which are mullock, waste residue, mine hole and stream. Furthermore, Pottiaceae and Bryaceae grow on waste furnace while Bryaceae and Brachytheciaceae belong to epiphyte; (3) the species similarity coefficients of waste furnace and waste residue, waste residue and stream, waste furnace and stream, waste residue and mine hole, mine hole and stream, waste furnace and mine hole on which bryophytes grow are 0.49, 0.46, 0.45, 0.41, 0.35 and 0.31 respectively which shows that the relationships are proximity. The species similarity coefficients between the bryophytes in mine hole and epiphytic b ryophytes and between epiphytic bryophytes and the bryophytes in stream are 0, which shows that the relationships are not exist; (4) the phytogeographical elements of the bryoflora include North Temperate(27.06%), Endemic to China(24.71%), E astern Asia(17.65%), Tropical Asia(14.12%), Cosmopolitan(7.06%), Pantropical(3.53%), Old World Temperature(2.35%), Tropical Asia and Tropical Australia(1.18%), Tropical Asia and Tropical Africa(1.18%) and Temperate Asia(1.18%); (5) the life forms are short turfs(71.76%), wefts(21.18%), tall turfs(2.35%) and mats(2.35%) as well as annuals(2.35%).
