摘要: 研究物种丰富度以及时空分布格局对区域生物多样性保护具有重要意义。为掌握湖南南岳衡山国家级自然保护区两栖动物的物种组成与时空变化,分别于2018年4、6和8月,运用样线法对衡山观测样区及周围区域两栖动物的资源现状与栖息地利用现状进行实地调查。调查共记录到15种两栖动物,隶属于1目6科12属,其中国家二级保护物种1种、"三有"动物10种,占物种总数的73.3%。区域内两栖动物的物种多样性在时间及空间尺度上均存在显著差异。其中,生物多样性指数在6月最高;4种典型生境中观测到的物种数存在明显差异,农田物种多样性最丰富,为12种,其余依次为水塘(9种)、溪流(6种)、林地(3种)。此次衡山自然保护区两栖动物观测基本掌握了该地区两栖动物的物种多样性及其时空格局,在此基础上分析评估了该地区两栖动物生存面临的胁迫因素,并对两栖动物的保护和管理提出了相关建议。

Abstract: Understanding the species richness and its spatial and temporal distribution pattern in certain region is of great significance for the protection of regional biodiversity. In order to master the species structure of amphibians as well as its dynamic changes of spatial and temporal distribution in the Nanyue Hengshan National Nature Reserve, Hunan, the amphibian resources status and the situation of habitat utilization in this region were investigated by line transect sampling in April, June and August 2018 respectively. A total of 15 species of amphibians were observed during the monitoring, which belongs to 12 genera, 6 families, 1 order. There were 11 species of amphibians belonging to nationally protected animal, accounted for 73.3% of the total 15 species in this survey. The results of this dynamic monitoring work show that the species diversity of amphibians had significant differences in time and space scale. In terms of inter-monthly biodiversity, the species diversity index was the highest in June. The species of amphibians observed in 4 different typical habitats were different significantly, in which farmland had the richest species diversity, followed by pond with 9 species, stream with 6 species and forest land with 3 species. The survival stress factors of amphibians in their habitats and distributional regions were analyzed and evaluated, and some suggestions for the protection and management of amphibians in this area have proposed.
