摘要
本研究通过对保存于山东师范大学植物标本馆(SDNU)的3 200余份采自山东的真藓科Bryaceae苔藓植物标本进行整理、鉴定,得出山东省真藓科植物名录,分析了生境和海拔等因素对山东真藓科植物分布的影响,并比较了2000年之前与之后采集种类的组成差别。结果表明:(1)山东真藓科植物有8属53种,其中山东新记录属2个——小叶藓属Epipterygium Lindb.和平蒴藓属Plagiobryum Lindb.,山东新记录种22个;(2)山东真藓科植物生境类型有土生、岩面薄土生、石生和树生四种,土生类型最多,偶见树生类群;(3)随着海拔升高,山东真藓科植物种类先增加后减少,海拔300~600 m间种类最为丰富;(4)鲁东低山丘陵区和鲁中南山地丘陵区真藓科植物种类丰富,鲁西北平原区种类稀少;(5)以2000年为界,仅在2000年之前采集到的真藓科植物有9种,仅在之后采到的有4种。
More than 3 200 Bryaceae bryophyte specimens collected from Shandong preserved in SDUN were collated and identified. Then the checklist of Bryaceae in Shandong was obtained. The species distribution situations affected by habitats,elevation and so on were analyzed. And the species composition difference based on the specimens collected before and after 2000 were compared. The results showed that 53 species,8genera of Bryaceae were reported in Shandong,including 2 new report genera,Epipterygium Lindb. and Plagiobryum Lindb.,and 22 new report species. There were 4 habitat types,on soil,on thin soil over rocks,on rocks and on tree trunks. The most common type was on soil,while rare on tree trunks. The species of Bryaceae in Shandong increased firstly and then decreased with the altitude increasing,and was the most abundant in the altitude belt of 300 ～ 600 m. The Bryaceae species was abundant in low hilly areas of eastern Shandong and hilly areas of central-south Shandong,while little in plain areas of northwest Shandong. There were9 species,which were only collected before 2000,and 4 species,which were only collected after 2000.
