黑龙江省东部煤矿区啮齿动物物种多样性分析

Diversity Analysis of Rodent Species in the East Coal-mining Areas in Heilongjiang Province

为了掌握人为干扰活动比较大的矿区啮齿动物组成,为有关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,于2010年3～11月通过实地调查,利用夹日法结合已采集到的标本,并对文献进行综合整理。结果表明黑龙江东部矿区啮齿动物12种,隶属3目5科10属,占黑龙江省啮齿动物的40%,在动物区系组成上以古北界为主(83.33%);从捕获数量上来看以褐家鼠(Rat-tus norvegicus)为优势种,啮齿动物在居民点的密度大于林地,符合矿区生境特点。

In order to master the composition of rodent which largely suffered from man-made interference,to provide scientific evidence for related departments to prevent rat pest and to provide general biology materials for rodent research,a on-the-spot investigation was carried out from March,2010 to November,2010 using clip day methods,combining with the previously gathered samples,relevant documents were sorted out.The findings showed that there were totally 12 kinds of rodents,belonging to 3 orders 5 families 10 categories,accounting for 40% of Heilongjiang rodents,in the composition of animal fauna palearctic realm was dominant（accounting for 83.33%）,while Rattus norvegicus was dominant species according to the captured number.The density of Rodent in was larger in settlements than in woodland,catering to the features of ecological habitat.
