摘要

在人口密集、城市化程度高的地区(如浙江省),由于人类活动、土地利用变化和栖息地破碎化等因素,物种面临着巨大的环境压力,影响着物种组成和多样性。中国东部地区是东亚地区特有苔藓植物分布最集中的地区之一,但也面临着生境不足的威胁。为了进一步了解九龙山国家森林公园苔藓植物的生境和多样性,研究了九龙山国家森林公园不同生境条件下苔藓植物的种类组成、生境偏好以及物种多样性差异。其中,共采集苔藓植物108份,隶属于21科32属46种。此外,我们还发现了12种浙江省从未记录过的苔藓植物。值得注意的是,40.74%的苔藓植物生长在天然岩石上,其次是林下植被和路边生境。Patrick丰富度指数(R)在不同生境间差异最大(p < 0.001)。从保护的角度来看,应保留天然岩石、道路和林下植被,以保护苔藓植物的多样性。

Habitat preference and diversity of bryophyte in the Jiulongshan National Forest Park, Eastern China
In densely populated, highly urbanized regions such as Zhejiang Province (eastern China), species are under enormous environmental pressures resulting from human activities, land use changes, and habitat fragmentation, which affect species composition and species diversity. Although eastern China is one of the most concentrated distribution areas of endemic bryophytes in East Asia, these species are also faced with the threats of habitat inadequacy. In order to get more information on bryophyte habitat and diversity, we investigated species composition, habitat preference, as well as species diversity differences of bryophytes under different habitat conditions in Jiulongshan National Forest Park (JNFP). In particular, the results showed that 108 specimens of bryophyte were collected in total, including 46 species in 32 genera of 21 families. Furthermore, we had found 12 species of bryophytes that had never been recorded before in Zhejiang Province. Remarkably, 40.74% of bryophytes were found to grow on natural rocks, followed by understories and roadside habitats. In addition, the Patrick richness index (R) varied most significantly among different habitats (p < 0.001). In a conservation perspective, natural rocks, roadways and understories should be preserved to protect bryophyte diversity.
