摘要:

于2006年8月,采用路线调查法对广西达洪江自然保护区的两栖动物进行调查。调查结果表明,该保护区有两栖动物17种,隶属11属5科1目,动物区系组成以华中区与华南区共有种为主,占整个保护区两栖动物物种总数的64.7%;17种两栖动物的海拔替代性分布不明显。达洪江自然保护区的两栖动物群落和同样地处桂西的龙滩自然保护区、底定自然保护区、岑王老山自然保护区的两栖动物群落相似系数较高,而与桂东北地区的猫儿山自然保护区和桂林漓江风景区的两栖动物群落相似系数最小。

Abstract:

The amphibians of Dahongjiang Nature Reserve of Guangxi were investigated with a method of route survey in August, 2006. The results show that 17 species of amphibians, belonging to 11 genera, 5 families, 1 order, are recorded in the reserve. The fauna is mainly composed of species distributed both in Central and South China Region, accounting for 64.7% of the whole species in the reserve. Altitude alternative distribution of 17 species of amphibians is not obvious. Compared to Longtan Nature Reserve, Diding Nature Reserve and Cenwanglaoshan Nature Nature Reserve that located in the west of Guangxi similarly, the similarity coefficient of amphibian communities in Dahongjiang Nature Reserve is higher. On the contrary, it has the smallest similarity coefficient than in Maoershan Nature Reserve and in Guilin Lijiang scenic spots of northeast of Guangxi.
