江西省两栖类动物多样性与地理区划

本研究整合近年来江西省两栖类动物物种分布新纪录，对江西省两栖类动物多样性进行编目整理。结果表明，近年来江西省新增23种两栖类物种分布新纪录，两栖类动物累计达2目8科58种，包括2种国家Ⅱ级重点保护物种和40种中国特有种。江西省两栖动物区系组成以东洋界华中区和华南区共有种为主，无古北界种类。东洋界种类54种，占总种数的93.1%，广布种4种，占总种数的6.9%。生态类型以流水型最多，陆栖-静水型次之。对13个保护地两栖类动物物种组成的聚类分析将其分为4个聚类群：赣北、赣东北、赣南、赣西。聚类结果在一定程度上支持早期江西省两栖动物地理区划，我们建议将罗霄山脉划为单独的赣西（罗霄）山地省。

The Amphibian Species Diversity and Zoogeographic Division in Jiangxi Province

This study summarized the new amphibian species recorded in Jiangxi Province and evaluated the species diversity. In recent years, Totally 58 amphibian species distributed in Jiangxi Province, of 23 were accumulatively recorded in recent years. Among those amphibian species, 40 are endemic to China, and 2 are nationally protected as the second ranked species,. The component of fauna consists 54 oriental species that distribute in the Central China and South China. No Palaearctic amphibian species were recorded, and 4 species were widely distributed in both oriental region and Palaearctic region. The ecological types of amphibians mainly were consisted of running water type, followed by Terrestrial and Quiet-water type. The result of hierarchy clusters analysis by the amphibian species distributed in 13 protected areas indicated 4 significant clusters: Ganbei, Gandongbei, Gannan, Ganxi, which partially supported the amphibian zoogeographic division of Jiangxi Province early proposed. Meanwhile, amphibians in Luoxiao Mountains were suggested to be a separate zoogeographic division, named Ganxi (Luoxiao) mountain area.
