【摘要】 目的明确广西木论国家级自然保护区药用两栖爬行动物资源现状、分布及区系特点。方法通过野外20条样线的实地调查,并参考相关文献,对保护区内药用两栖爬行动物资源进行分析。结果该保护区药用两栖爬行动物有66种,其中,药用两栖动物21种,隶属2目8科15属;药用爬行动物45种,隶属于2目14科31属。G-F指数计算结果表明,保护区药用两栖爬行动物的物种多样性均处于较高水平,药用爬行动物的科属多样性水平比药用两栖动物较高。保护区内两栖爬行动物区系表现出以东洋界华中华南区共有种为优势的动物区系特点,区系相似性比较结果表明保护区区系相似性跟地理距离远近没有关系。药用两栖动物生态类型以陆栖-静水型为最多,流水型类型次之。保护区内有国家Ⅰ级重点保护野生动物1种,国家Ⅱ级重点保护野生动物3种,列入IUCN极危等级的物种2种,濒危7种,易危12种。结论广西木论国家级自然保护药用两栖爬行动物资源丰富,然而其生存受到多种因素严重威胁,文章研究结果为保护区的中药资源保护提供基础资料和参考。更多还原

【Abstract】 Objective To understand the resource, distribution and fauna characteristics of medicinal herpetological in Mulun National Nature Reserve, Guangxi. Methods We carried out 20 lines transect and referred to relevant literatures to analyze the medicinal herpetological resource in this area. Results A total of 66 species of medicinal amphibians and reptiles were finally recorded in the reserve, among of which,21 species of amphibians belong to 15 genera,8 families and 2 orders, and 45 species of reptiles belong to 31 genera 14 families and 2 orders. The results of G-F index indicated that the species diversity of medicinal amphibians and reptiles is at a higher level, and the diversity of families and genera of medicinal reptiles is higher than that of medicinal amphibians. Most of the medicinal amphibious and reptile in the reserve were distributed in the central and southern China of the Oriental realm. The results of the average faunal resemblance(AFR) between the reserve and five national nature reserves in Guangxi showed that there the reserve AFR has nothing to do with geographical distance. The ecological types of medicinal amphibians are mostly terrestrial-quiet water type, followed by water type. There are one species of class Ⅰnationally key protected wild animals and two species of class Ⅱ nationally key protected wild animals. Two, seven, twelve species were classified as critically endangered, endangered and vulnerable categories of IUCN, respectively. Conclusion There are abundant resources of medicinal amphibians and reptiles in Mulun National Nature Reserve, Guangxi. However, their survival is seriously threatened by many factors, which our results would provide basic information and reference for the protection of traditional Chinese medicine resources in the nature reserve.更多还原
