上海金山岛自然保护区苔藓植物再调查

2001～2002年在对上海金山岛自然保护区3次野外再调查采集的基础上，报道了金山岛苔藓植物24科42属62种．与1986～1990年调查结果相比，该区种类丰富，发现了上海新记录属2个，小叶藓属(Epipterygium)和拟鳞叶藓属(Pseudotaxiphyllum)新记录种16种．上海市区常见的随人苔藓植物未见生长，当年记录的部分树生和主要分布在热带的种类未见生长和分布．结果说明：一方面保护区坚持自然保护，人为干扰小，丰富的苔藓种类得以保护和繁衍；另一方面可能受隔岸金山石化区的影响，对环境敏感的种类正在消亡．另外，还对保护区苔藓植物生境和区系成分进行了分析，提供了详细名录．

A re-survey of Bryophytes on the Jinshan Island Nature Reserve, Shanghai

Based on re - survey of three - times field work on Jinshan Islands Nature Reserve in Shanghai during 2001 - 2002, 62 species belonging 42 genera and 24 families of bryophytes are reported. Compared with the results recorded in 1986 - 1990, there are richer diversity of bryophytes in the reserve, two genera, namely Epipterygium and Pseudotaxiphyllum , and 16 species are newly recorded to Shanghai region. The common species in the urban area such as Funaria, Physcomitrium ets. have not been found. However, some epiphytic species and species belonging tropical elements were also not found and collected again. The resultes implied that: (1) the rich flora of bryophytes at the Reserve has been well preserved by protection of nature habitats and from human being activities; (2) some taxa of bryophytes are endanged and might be disappeared by pollution effects from the Jinshan Chamical industrial district nearby. The habitats and geographic flora of bryophytes on the island are also analysed. A list of bryophytes collected is presented.
