托木尔峰国家级保护区苔藓植物生态群落调查

Research on bryophyte community type in Tomur Peak National Natural Reserve

通过对托木尔峰国家级自然保护区苔藓进行调查与种类的鉴定统计得出,该地区现知苔藓植物41科,79属,246种(含9个变种),其中藓类22科,54属,202种,苔类19科,25属,44种;其中侧蒴藓类为65种,顶蒴藓类为137种.该保护区苔藓植物物种多样性丰富的优势科(种数≥10)分别为丛藓科、真藓科、紫萼藓科、青藓科、提灯藓科、柳叶藓科;优势属(种数≥6)分别为真藓属、对齿藓属、青藓属、紫萼藓属、灰藓属、提灯藓属、木灵藓属、赤藓属、大帽藓属、丝瓜藓属.将该区的苔藓群落分为土生,石生,木生及水生群落等4种生态类型.该区以土生群落为主,占69.1%,其次是石生群落,木生群落,分布最少的是水生群落.

Based on detailed field investigation,collection of specimens and identification of Tomur Peak National Nature Reserve,about 246 species,which belongs to 79 geneus and 41 families(including subspecies)were reported in this paper.Among them the pleurocarpous mosses are 65,acrocarpous mosses are 137,both of them belong to 11 families.Pottiaceae,Bryaceae,Grimmiaceae,Brachytheciaceae,Mniaceae and Amblystegiaceae are the dominant families and Bryum,Didymodon,Brachythecium,Grimmia,Hypnum,Mnium,Orthotrichum,Syntrichia,Encalypta and Pohlia are dominant genus.In this area there are four types of bryophytes communities recogonized:Hydrophytia,Petrophytia,Geophytia and Epixylophytia.Geophytia is the dominant one and the Hydrophytia is scarce.
