| 摘 要： | 贺兰山独特的地势地貌和植被垂直分布特点,为啮齿类动物的群落结构和分布特征研究提供了良好条件。在2013年分春、夏、秋3个季节,采用铗日法对内蒙古贺兰山的啮齿动物种类组成和海拔梯度分布情况进行了细致研究。调查选取了8条典型沟道,共布设有效铗日18 748个,捕获啮齿动物235只,隶属2目5科11属13种。捕获种类最多的为哈拉乌沟(11种),最少的是雪岭子沟和甘树湾沟,各捕获2种。啮齿动物多样性垂直分布特点总体上呈现中间高两头低的趋势,符合"驼峰形"格局。

| Abstract: | The unique topography and vertical distribution of vegetation in the Helan Mountains provide good conditions for study of the community structure and distribution of rodents.From spring to winter of 2013,we trapped rodents to quantify their species composition and elevational distribution in Inner Mongolia,Helan Mountain National Nature Reserve.18 748 traps were laid in 8 typical gullies,and 235 rodents were caught,representing 13 species,11 genera,5 families and 2 orders.The spot with the largest capture number of species was Halawu Gully where 11 species were caught.Ganshuwan Gully and Xuelingzi Gully had fewest species at two each.Rodent species richness was generally higher at intermediate elevations and lower at high and low elevations,yielding a“humped”pattern of elevational distribution. |
