摘要
为明晰广西两栖动物资源概况,通过总结近20余年发表的文献资料,从种类组成、区系特点、地理分布、生态类型、保护等级等方面对广西两栖动物进行区系统计分析。结果显示,广西现记录两栖动物3目11科37属111种,主要分布在桂北(83种,占74.8%)和桂南(66种,占59.5%)地区。其中,东洋界种107种、占97.3%,广布种3种、占2.7%,无古北界种。东洋界种中,华南区成分36种、占33.6%,华中区成分29种、占27.1%,华中华南区成分25种、占23.4%,西南区成分12种、占11.2%,华中西南区成分5种、占4.7%。列入《中国物种红色名录》43种、占38.7%,省级重点保护动物14种、占12.6%。分析表明,广西两栖动物资源具有以东洋界种类为主、省内各区分布不均、生态类型多样、珍稀濒危保护种类丰富等特点。
In order to understand the status of amphibian resource in Guangxi, the species composition, fauna, distribution, ecological categories and protective grade of amphibians were counted and analyzed respectively by studying literature published in the recent 20 years. A total of 111 species of amphibians were listed under 37 genera, 11 families and 3 orders. Most of them were distributed in north （83 species, 74.8%） and south （66 species, 59.5%） parts of Guangxi. A total of 107 （97.3%） of them were oriental realm species, 3 （2.7%） widespread species, and none belonged to palearetie realm species. Within the oriental reahn species, 36 （33.6%） of them were originated in the south area of China, 29 species （27.1%） were originated in the central area of China, 25 species （23.4%） were originated in the central and south area of China, 12 species（11.2%） were originated in the southwest area of China, and 5 species（4.7%） were originated in the central and southwest area of China. A total of 43 species（38.7%）were listed in the ＂China Species Red List＂, and 14 species （12.6%） were listed as protected species in Guangxi. The analysis indicates that the amphibians in Guangxi were non-random distribution and the fauna of Guangxi was dominated by oriental realm species and the ecological categories was more and most of them were listed as protected species.
