广西元宝山自然保护区两栖动物资源调查及保护

Survey and Conservation of Amphibia Resources in Yuanbao Mountain Nature Reserve of Guangxi Province

2009年3～8月,对广西元宝山自然保护区的两栖动物资源进行了调查。结果表明,该保护区有两栖动物27种,隶属18属8科2目;物种多样性指数为2.877,均匀度指数为0.873。动物地理区划属东洋界华中区西部山地高原亚区黔桂湘低山丘陵省,区系组成以华中区与华南区共有种为主;生态类型以流水型和陆栖静水型种类占优势;保护区和同样地处桂北的猫儿山自然保护区、桂林漓江风景名胜区的两栖动物群落相似系数较高,而与桂西地区的岑王老山自然保护区、龙滩自然保护区、底定自然保护区和桂南地区的十万大山、挂榜山的相似系数较小。最后,根据资源现状提出了保护对策。

The amphibian resources in Yuanbao Mountain Nature Reserve of Guangxi were investigated from March to August in 2009.The results showed that 27 species of amphibians,belonging to 18 genera,8 families,2 orders,were recorded in the reserve.The Shannon-Wienner diversity index and Pielou evenness index were 2.877 and 0.873 respectively.According to the zoogeographic division,this area belong to Western mountain and plateau subregion,Central China region,Oriental Realm.The fauna is mainly composed of species distributed in both Central and South China Region.The ecological categories of 27 amphibians are mainly running-water type and Terrestrial Quiet-water type.Compared to Maoershan Nature Reserve and Guilin Lijiang scenic spots located in the north of Guangxi similarly,the similarity coefficient of amphibian communities in Yuanbao Mountain Nature Reserve is higher.On the contrary,it has smaller similarity coefficient than Cenwanglaoshan Nature Reserve,Longtan Nature Reserve,Diding Nature Reserve of west of Guangxi and Shiwandashan,Guabang mountain of South of Guangxi.Based on the status of the amphibian resources,some protective suggestions were provided in the paper.
