| 摘要: |
| 以岱山炮台山为研究区域，设立了80个样地，其中普通样地36个，坟墓样地44个.系统调查了样地中苔藓植物种类和盖度，发现炮台山地区共有苔藓植物21科36属71种，其中苔类5科5属6种；坟墓样地中分布的苔藓植物有14科22属38种；普通地面生苔藓植物有20科32属58种.坟墓生苔藓植物物种多样性指数明显低于地面生的；在坟墓样地中，同一个坟墓的穴顶样地苔藓植物物种多样性指数大多高于背沟样地、台面样地和背墙样地的；坟墓和普通地面环境下苔藓植物种类组成和数量发生情况各有特点，相对于普通地面生苔藓，坟墓生苔藓盖度大，但种类单一、均匀度低、多样性小.总体上，坟墓修建降低了当地的苔藓植物多样性. |

| Abstract: |
| 44 plots,including 36 common plots and 11 tomb plots,were set up in PaoTai Mountain of Daishan.The species and coverage of bryophytes in the sample plots were investigated systematically,and the biodiversity index was measured.The 71 species bryophytes belonging to 21 families and 36 genera were found in PaoTai Mountain.The 38 species bryophytes belonging to 14 families and 22 genera were found on tomb.The 58 species bryophytes belonging to 32 families and 32 genera were found under ground.The species diversity of bryophyte plants distributed in tomb plots is lower than that of common terrestrial bryophytes.In the tomb plots,the diversity index of the top plot of the same tomb is higher than that of the back ditch plot,the mesa plot and the back wall plot.Tomb and common ground bryophytes have their own characteristics.Although the coverage of tomb bryophytes is larger,the species composition of tomb bryophytes is more single and the diversity is lower.Generally speaking,folk tombs are not conducive to the protection of the diversity of bryophytes. |
