西双版纳布龙州级自然保护区两栖爬行动物多样性

2011年3月~2012年6月,经多次野外调查及访查,共记录到西双版纳布龙州级自然保护区两栖爬行动物74种。其中,两栖类34种,隶属于2目7科;爬行类40种,隶属于3目13科。两栖爬行动物中属国家I级重点保护2种;Ⅱ级重点保护4种。列入《国家保护的有益的或者有重要经济、科学研究价值的陆生野生动物名录》的有65种;云南特有种8种;西双版纳特有种4种。多样性指数分析表明,两栖爬行动物的多样性丰富,其多样性指数(D)分别为5.305 2和6.745 3。爬行类的DG-F高于两栖类,表明爬行类科属间多样性更高。据此,对该地区两栖爬行动物区系特征、保护措施等进行了分析。

Diversity of Amphibian and Reptilian in Bulong State Nature Reserve of Xishuangbanna

The surveys were conducted from March 2011 to June 2012 in Bulong State Nature Reserve of Xishuangbanna. Results showed that there were total 74 species of amphibian and reptilian,including 34 species of amphibian belonged to 2 orders and 7 families,and 40 species of reptile belonged to 3 orders and 13 families. Among them,2 species were ranked as state class I,and 4 species as class Ⅱ of national key protected species; 65 species were confined as the useful and important economic or scientific species of China; 8 species were endemic to Yunnan,and 4 species were endemic to Xishuangbanna. The diversity of amphibian and reptiles were more abundant which diversity index was 5. 305 2 and 6. 745 3separately. G-F index of reptiles was significantly higher than that of amphibians,indicating higher species diversity in reptiles than that in amphibians. Accordingly,the characters of herpetological fauna and distribution were analyzed in the paper.
