贵州洋溪自然保护区兽类资源及其特征分析

Mammal Survey at Yangxi Nature Reserve,Guizhou Province

2014年4月~2015年春,采用样带法、红外相机陷阱法、夹日法、网捕法及非诱导性访问调查法对贵州洋溪保护区兽类资源进行了初步调查,结合史料及文献,确认了保护区现有兽类组成。1保护区现有兽类43种,隶属于8目19科;2动物区系方面,广布种(26种)占绝对优势;东洋型物种(23种)最多;3国家I级保护动物1种,II级保护动物8种;IUCN濒危物种2种,易危1种,近危6种;列入CITES附录的物种有9种;47种生态类型中,地面生活型物种最多(18种);5Jaccard相似性分析显示,洋溪保护区与佛顶山保护区兽类群落中等相似(C=0.62)。不同物种对生境的要求不一样,应加强生境保护、修复及物种保育、监测工作。

We surveyed mammals at Yangxi Nature Reserve with line transect, infrared camera - trapping, snap - trapping, net trapping and non - inducing interview from April 2014 to spring 2015. We confirmed the mammal fauna by comparing our field survey results with historical data and literature. The mammalian fauna included 43 species, of 8 orders and 19 families. Widespr-ead species were dominant in the animal fauna with 26 species, and 23 species of Oriental fauna are dominant among the six distribution types. One species is listed as class I national protected species of China, and 8 species as class II. Among the 43 species, 2 are listed as Endangered in the IUCN Red List, 1 species is Vulnerable, and 6 species are Near Threatened; 9 species are listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Mammals at the reserve can be classified into 7 ecological forms according to the habitats and hab- it. Most species are terrestrial（ 18 species）. Similarity analysis showed that communities between Yangxi and Fodingshan Nature Reserve are moderately similar, the index of similarity （C） was 0. 62 for the two reserves. Different species require different habitats, so it is important to strengthen habitat protection, restoration, wildlife conservation and long -term monitoring.
