| 摘要: |
| 鄂西南地区密集分布有后河、木林子、七姊妹山和星斗山四大国家级自然保护区, 共同形成了一个珍稀动植物大体相近、互相补充的保护区群,为摸清鄂西南保护区群的苔藓植物组成,该文采用野外调查和文献资料整理相结合的方法,对鄂西南国家级自然保护区群内的苔藓植物丰富度和组成特征进行了分析,并与渝东南、湘西北的苔藓植物多样性进行了比较。结果表明:(1)鄂西南国家级自然保护区群共有苔藓植物77科197属601种,物种数分别占中国和湖北苔藓总数的19.89%和71.46%。其中,中国特有种27种,仅含1种的科有15科,仅含1种的属有91属。(2)鄂西南国家级保护区群内的各保护区之间的苔藓物种存在一定的相似性与互补性,符合我国生物多样性保护原则。(3)鄂西南国家级自然保护区群苔藓植物区系类型全面,物种数量也显著高于同处武陵山区的渝东南、湘西北等地区。因此,鄂西南国家级自然保护区群不仅有效地保护了大型珍稀濒危动植物,而且还孕育了丰富多彩的苔藓植物类群为苔藓植物营造了良好的居住环境,是苔藓植物多样性保护的重要场所。 |

| Abstract: |
| In the Southwest of Hubei Province, there are four national nature reserves, namely Houhe, Mulinzi, Qizimeishan and Xingdoushan. Together they form a interconnecting protected area in which rare animals and plants are similar and complementing each other. At the same time, its rich landform types and water resources created an excellent living environment for bryophytes. This paper used the method of combining field investigations and published records to analyze the species richness and composition of bryophytes in these national nature reserves of Southwest Hubei, and to compare the diversity of bryophytes with those in Southeast Chongqing and Northwest Hunan. The results were as follows:(1)There were 601 species of bryophytes of 197 genera and 77 families in the national nature reserve group of Southwest Hubei, accounting for 19.89% and 71.46% of the total number of bryophytes in China and Hubei, respectively. Among them, 27 species are endemic to China, 15 families and 91 genera have only one species each.(2)There are some similarities and complementarities among bryophytes in the four national nature reserves within the national nature reserve group, it conforms to the principle of biodiversity conservation in China.(3)The bryophytes flora compositions in the national nature reserve group in Southwest Hubei are diverse, and the number of bryophytes species is significantly higher than that in Southeast Chongqing and Northwest Hunan. Therefore, the national nature reserve group in Southwest Hubei not only effectively protects large-sized rare and endangered plants and animals, but also nurtures a rich and diverse bryophytes flora, thus an important area for of the conservation bryophytes diversity. |
