贵州赤水桫椤国家级自然保护区桫椤群落苔藓植物调查
|
摘要
对赤水桫椤国家级自然保护区18个桫椤植物样方苔藓植物进行采集,共获165份标本。经鉴定分析,有苔藓植物26科37属61种,其中苔类植物8科10属16种,藓类植物18科27属45种;优势科有5个,分别是齿萼苔科、白发藓科、凤尾藓科、毛锦藓科、灰藓科;优势属有5个,分别是白发藓属Leucobryum、梳藓属Ctenidium、曲柄藓属Campylopus、凤尾藓属Fissidens、异萼苔属Heteroscyphus;苔藓植物种类较丰富的样方多位于沟边、沟谷潮湿的地带,在草本、蕨类、小灌木等小型植物少、桫椤植物幼苗少及腐殖质层厚的环境中,苔藓植物分布也较多;生境分析结果显示,石生基质种类最多,占总种数的85.25%。
Based on 165 bryophyte samples collected from 18 Alsophila plant quadrats of Chishui Alsophila Nature Reserve, 61 species belonging to 37 genera in 26 families were identified. Among these species, 16 species of 10 genera in 8 families were liverworts, 45 species of 27 genera in 18 families are mosses. Dominant families included Lophocoleaceae, Leucobryaceae, Fissidentaceae, Pylaisiadelphaceae and Hypnaceae. Dominant genera included Leucobryum, Ctenidium, Campylopus, Fissidens, Heteroscyphus. The quadrats with rich bryophyte species were located in moist valleys, in addition, bryophytes distributing more frequently in the environments where there were few small plants such as herbs, ferns and shrubs, few seedlings of Alsophila, or thick humus. Epilithic bryophytes were most abundant and accounted for 85.25% of all species.
