木林子国家级自然保护区苔藓植物物种与区系研究

Study on bryophyte species and flora in Mulinzi National Nature Reserve

  • 摘要: 基于野外调查、采集标本和查阅文献,对木林子国家级自然保护区苔藓植物物种及区系特点进行研究。结果显示:该保护区苔藓植物共有64科121属292种,其中,苔类28科38属88种,藓类36科83属204种。该保护区共有湖北新记录科2科、新记录属9属、新记录种73种。该保护区苔藓植物区系成分多样,有11个区系类型,以温带成分为主(占30.89%)、东亚成分次之(占18.92%)。相比清凉峰、大巴山、十万大山和佛坪4个国家级自然保护区,木林子呈现出科多种少的特点,物种分化程度更高。木林子保护区与清凉峰的苔藓植物组成相似度最高,与佛坪相似度最低。该研究结果从苔藓植物多样性的角度佐证了清江流域物种分化程度较高的观点,为丰富木林子国家级自然保护区苔藓植物和湖北省苔藓植物提供了基础资料。

     

    Abstract: Based on field investigation, specimen collection, and literature review, we studied the species and floristic characteristics of bryophytes in Mulinzi National Nature Reserve, China. Based on our results, a total of 64 families, 121 genera, and 292 species of bryophytes were identified in the study area. Among them, 204 species, 83 genera, and 36 families were mosses, 88 species, 38 genera, and 28 families were liverworts, and 2 families, 9 genera, and 73 species were newly recorded in Hubei. The floristic composition of bryophytes was diverse, with 11 floristic types, mainly Temperate (30.89%) and East Asian components (18.92%). Compared with the Qingliangfeng, Dabashan, Shiwandashan, and Foping National Nature Reserves, Mulinzi National Nature Reserve exhibited a lower degree of species differentiation and greater family but lower species richness. The similarity in bryophyte composition between Mulinzi and Qingliangfeng was the highest, whereas similarity between Mulinzi and Foping was the lowest. From the perspective of bryophyte diversity, this study supports the viewpoint that species differentiation is higher in the Qingjiang River Basin. This study provides basic data on bryophyte diversity in Mulinzi National Nature Reserve and Hubei Province.
