中文摘要:200281日~17日对四川美姑大风顶自然保护区的两栖爬行动物进行了调查。结合前人的工作,该保护区共有两栖爬行动物22种,其中两栖动物11种,隶属于972目,爬行动物11种,隶属于942亚目1目。区系特点为:(1)物种组成较丰富;(2)都属于东洋界物种,没有古北界的成分;(3)区系组成较简单,以喜马拉雅-横断山区型和南中国型为主;(4)特有种所占比例高;(5)既古老又具年轻的特点。美姑县新纪录6种,大凉疣螈为国家级重点保护野生动物。美姑大风顶自然保护区两栖爬行动物物种多样性和生境多样性较高,对于生物多样性保护和研究横断山脉两栖爬行动物物种组成及区系特征具有一定意义。
英文摘要:
From August 1st to 17th, 2002, the herpetological survey was conducted in Meigu Dafengding National Nature Reserve, Sichuan Province, China, from which specimens of 12 species of amphibians and reptiles were collected. Based on this survey and historical records, there are 11 species of amphibians, and 11 of reptiles, in this nature reserve. The former belong to 9 genera of 7 families of 2 orders, and the latter belong to 9 genera of 4 families of 2 suborders of 1 orden. The characters of the herpetofauna ale as follows: (1) There are rich species of amphibians and reptiles of different genera and families; (2) All of the above species belong to Oriental realm, most of which are distributed in the southwest China, without species of the north; (3) The components of the herpetofauna of Meigu Dafengding National Nature Reserve are principally Himalaya-Hengduan Mountains forms and South China forms, with a small proportion of Oriental forms. (4) There is a large proportion of endemic species; (5) There are both primary and young components in this nature reserve. Owing to less influence of the glacier during the quaternary period, there retain rich biodiversity in both species and habitat level, and many primary species, especially those of amphibians, still exist in this region.
There are 6 new records of Meigu County, which are discovered in this survey. Some discussions of endangered species, especially Elaphe perlacea, and some suggestions are given in this paper.
