摘 要 ：研究发现新路卡林型金矿区苔藓植物有10科17属28种，其中，丛藓科有9种，占总数的32.14%，真藓科有8种，占总数的28.57%。真藓科和丛藓科为优势科。分析该卡林型金矿区4个生境的β多样性，发现废石区—废渣区与相对污染区—清洁区的β多样性指数差异最大，苔藓群落结构差异性最大，相似性成分最低。测定该矿区苔藓植物及相应基质的重金属元素Pb、Zn、Cu、Cd、Hg、As含量，发现这些重金属元素含量呈现了一定的规律性，即：废渣区>废石区>相对污染区>清洁区，这可能与金矿的开采和冶炼有密切联系。因此，通过对苔藓植物的深入研究，可用以监测卡林型金矿区重金属污染情况。

Abstract:Twenty-eight bryophyte taxa in 17 genera of 10 families from Xinlu Carlin gold field were investigated. Nine species belong to Pottiaceae and 8 species belong to Bryaceae. Among them, Pottiaceae and Bryaceae are the dominate families. By analyzing β diversity of four sites in this area, we found that β diversity difference between barren rock field-waste residue field and relatively polluted area-clear area is the largest, bryophyte community structure is the biggest difference, and similarity is the lowest. A particular regularity was proved by monitoring 6 kinds of heavy metals Pb, Zn, Cu, Cd, Hg, As of bryophytes and their substrates from different areas in Xinlu Carlin gold deposit, that is waste residue field>barren rock field>relatively polluted area>clear area. It might be closely related to the mining and smelting. Obviously, further researches on bryophytes can be used to monitor the pollution of heavy metals in gold deposits.
