江西省阳际峰自然保护区苔藓植物区系研究

Study on bryophyte flora from Yangjifeng Nature Reserve,Jiangxi Province,China

对江西省阳际峰自然保护区3000号标本进行鉴定,发现该地区共有苔藓植物57科133属297种(含种下级单位),其中藓类植物33科94属207种,苔类植物24科39属90种;≥10种的苔藓植物优势科有细鳞苔科Lejeuneaceae、灰藓科Hypnaceae、蔓藓科Meteoriaceae、锦藓科Sematophyllaceae、丛藓科Pottiaceae、绢藓科Entodontaceae、曲尾藓科Dicranaceae、青藓科Brachytheciaceae、真藓科Bryaceae、提灯藓科Mniaceae、羽藓科Thuidiaceae等11科,占该区苔藓植物总科数的19.30%,该优势科所含种数为157种,占总种数的52.86%;该区苔藓植物区系成分以东亚、北温带和热带亚洲成分为主,分别占总种数的34.70%、19.03%和14.18%.通过与中国其他9个山地苔藓植物区系的相似性比较,发现阳际峰自然保护区苔藓植物区系与金佛山、马头山、古田山亲缘关系较近,具有较明显的过渡性质.

A total of 3 000 speciesmens of bryophytes representing 297 species （including subspecies and varieties）,133 genera and 57 families were collected from the Yangjifeng Nature Reserve.Among them,207 species belonging to 33 families and 94 genera were mosses,and 90 species belonging to 24 families,and 39 genera were liverworts.Lejeuneaceae,Hypnaceae,Meteoriaceae,Bryaceae,Mniaceae,Thuidiaceae,Sematophyllaceae,Pottiaceae,Entodontaceae,Dicranaceae,Brachytheciaceae were the 11 major families（≥10 species）,and accounted for 19.30%,52.86% of the total families and species,respectively.Comparing the similarity of bryoflora from Yangjifeng with those from the other 9 mountains in China,the result indicated that the bryoflora from Yangjifeng Nature Reserve represented the transitional characteristic from temperate region to tropical region,and the geographical and floristic relationship was closed to those from Jinfo Moutain,Matou Moutain and Gutian Moutain.
