| 摘 要： | 报道英国约克郡国家公园5个钙华沉积地点苔藓植物群落调查结果。该区域钙华苔藓群落共13个,由12科15属18种组成。区系地理成分由北温带和世界广布两种成分组成;生活型以垫状矮丛集型和交织型占优势。根据钙华沉积环境特征,划分Cron钙华苔藓群落、洞穴钙华苔藓群落、瀑华苔藓群落、峭壁钙华苔藓群落和泉华苔藓群落等5种类型。调查结果表明,研究区现代苔藓植物群落钙华沉积作用十分显著。

| Abstract: | This paper is based
on a study of 52 samples and specimens of bryophyte collected from 5 active travertine
sites at Yorkshire Dale National Park, U.K. The bryoflora consists of 18 species and 15
genera in 12 families. According to Chen's classification (1958), there are 13 typical
bryophyte communities associated with travertine deposit in this area. The
phyogeographical elements of the bryoflora consist of Cosmopolitans (22.2%) and North the
Temperate (77.8%); 4 life-forms of bryophyte can be distinguished, among them,
chsion-short turfs and wefts predominate. The ecological distributional types of the
bryophyte at Yorkshire are as follows bryophyte communities on cron; bryophyte
communities on spring tufa; bryophyte communities on cave tufa;bryophyte communities on
cliff tufa; bryophyte communities on waterfall tufa.The travertine deposit associated with
bryophyte communities is active at Yorkshire Dale. |
