四川都江堰“中华熊猫谷”小型兽类组成及多样性分析

Composition and Diversity of Small Mammals in China Panda Valley,Dujiangyan,Sichuan Province

四川都江堰"中华熊猫谷"是新建的圈养大熊猫野化放归的训练场所。于2010年3月—2014年10月,采用夹日法对该地区小型兽类进行了5次调查。结果表明:1)2243夹日共采集到小型兽类标本238号(捕获率10.6%),隶属2目3科8属13种,其中,北社鼠Niviventer confucianus、短尾鼩Anourosorex squamipes和黑腹绒鼠Eothenomys melanogaster为优势种;2)以生境类型看,弃耕地群落捕获率(11.73%)高于次生林(8.98%);3)从小型兽类群落多样性看,弃耕地(H=0.670)与次生林(H=0.677)差别不大,但弃耕地物种数明显多于次生林;4)2010年到2014年调查期间,小型兽类的数量明显减少。

China Panda Valley is a new place for the training and releasing giant panda into the wild. However,no report was available on the information of small mammals in this area. Five investigations of small mammals were conducted from2010 to 2014 in China Panda Valley,Dujiangyan,Sichuan province. The results showed that： 1） a total of 238 individuals were captured with 2243 traps（ capture rate： 10. 6%）,and these individuals were belonged to 2 orders,3 families,8 genera and 13 species,meanwhile,Niviventer confucianus,Anourosorex squamipes and Eothenomys melanogaster were the three dominant species; 2） on the basis of local community types,the capture rate of the derelict land community（ 11. 73%） was significantly higher than that of the secondary mixed forest（ 8. 98%）; 3） Species diversity index of the derelict land community（ H = 0. 670） was similar to that of the secondary forest（ H = 0. 677）,however,the number of species in the derelict land was much higher than that in the secondary forest; 4） The amount of small mammals was significantly reduced during the period of investigation.
