牡丹峰自然保护区啮齿动物区系调查研究

Study on Rodent Fauna in Mu Danfeng Nature Reserve

为了更好的掌握牡丹峰自然保护区啮齿动物种类数量和区系分布,为林业部门预防鼠害提供科学依据,也为啮齿动物研究提供基础生物学资料,本文于2008年3月~2011年1月通过实地考察为主,结合以前采集到的标本以及对文献进行综合整理。该自然保护区共有啮齿动物13种,隶属2目4科11属,占黑龙江啮齿动物的43.3%,其中古北界10种（占76.9%）,广布种3种（占23.1%,）,在动物区系组成上以古北界为主,大林姬鼠（Apodemus peninsulae）为优势种。鼠类的密度与林龄有密切关系,林龄较长的林地鼠类密度较低,不同种类的鼠的分布也与植物的种类有关。为了更好的保护牡丹峰自然保护区的森林资源,要对保护区的啮齿动物进行定期监测。

To be competent in varieties of rodent faunal distribution,scientific evidence for Forestry Department preventing rodent pest and basic biology materials for rodent fauna research were provided,from March,2008 to January to 2011 on-the-spot investigation were carried out and documents combined with previously collected samples were sorted out.There was total of 13 kinds of rodent belonging to 2 orders 4 families 11 categories accounting for 43.2% of rodent in Heilongjiang Province,of which 10 kinds of palearctic realm（accounting for 76.9%）,3 kinds of dispersed species（accounting for 23.1%）,and we concluded that palearctic realm gave first place to the composition of fauna and that Apodemus peninsulae was dominant species.The density of rat was closely related with stand age,that was,woodland rat of longer stand age had a lower density.The distribution of different kinds of rat was also related with the varieties of plants.In order to protect forest resources in Mu Danfeng reserve for the better,we should monitor rodent fauna in reserve regularly.
