摘要
狮子山铜矿是长江中下游大型埋藏型铜矿之一,属矽卡岩型伴生金银铜矿床。对狮子山铜矿苔藓植物进行了采集,29份标本中鉴定出25种藓类(6科18属),未发现苔类。丛藓科Pottiaceae、曲尾藓科D icranaceae、真藓科B ryaceae是3个优势科,3科均含3属以上和5种以上,分别占总种数的44%、24%和20%,其他3科均为1属1种;净口藓属Gymnostomum、墙藓属Tortula、扭口藓属Barbula、真藓属Bryum和小曲尾藓属D icranella是优势属,5属总共包含了25种苔藓中的12种,占总种数的48%。对各采集点苔藓植物进行了分析,结果表明苔藓植物种类分布受到重金属、植被、气候和人类活动等多重因素影响。
Shizishan Copper Mine is a skam deposit living with gold and ciliver , one of the big buried Copper Mines in the downstream of Yangtze River. On the basis of 29 collections from this Copper Mine in Tongling,Anhui, 25 moss species （in 6 families and 18 genera）and no Hepatics and Anthocerote were found. Pottiaceae, Dicranaceae and Bryaceae were three predominant families, which all comprised 3 genera and 5 species above,separately contributed 44% ,24% and 20% of all moss species. The other three families involed 1 genus and 1 species each other, occupied 12% of all species in all. The 5 genera of Gymnostomum , Tortula ,Barbula ,Bryum and Dicranella were major genera, involed 12 species of 25 mosses species altogether and 48% of all species. Analyzed the mosses from different places, and indicated that bryophyte category distribution was under the influence of metal, vegegation, climate and factitiousness, etc.
