中文摘要	用3种不同的生态位宽度和生态位重叠测度方法,对内蒙古阿拉善荒漠11种主要啮齿动物的生态位进行了比较研究.结果表明,子午沙鼠的生态位宽度指数最高,3种方法计算结果分别为0.842、0.723、0.516.该种在7种生境中均有分布,且以人工草地和农田的数量最高,天然草地的数量最低,对7种资源等级的利用具有一定的选择性.五趾跳鼠的次之,分别为0.751、0.722、0.513.该种在7种生境中均有分布且数量差异不大,对7种资源等级的利用具有一定的普遍性.比较3种生态位宽度指数测度方法,以Shannon-Wiener Index对荒漠区啮齿动物较为适宜.生态位重叠指数最高的啮齿动物因计算方法的不同有1～9个种对,生态位重叠指数最低的有10～11个种对.分析比较3种生态位重叠指数测度方法,以Pianka Index更适合于荒漠区啮齿动物的生态位重叠测度.
英文摘要	Niches of 11 rodent species in the Alashan desert region of Inner Mongolia were studied by three different methods. The results showed that the niche breadth indexes of Meriones meridianus were valued 0.842,0.723 ,0.516, as the highest.lt distributed in 7 kinds of habitat, however, the highest density of this species was found in artificial grassland and crop land, the lowest density occurred in natural grassland. The niche breadth indexes of Allactaga sibirica were placed in the second which was reatched 0.751, 0.722, and 0.513.It was found in 7 kinds of habitat without much density difference Among the three measuring methods, Shannon-Wiener Index was morn suitable to describe niche breadth for desert rodents. The highest overlap index in niche was found in 1-9 species pair and the lowest one was occurred in 10 - 11 species pair when it was measured by difference methods . Comparation between the three methods for measuring niche overlap indexes, the Pianka Index was most applicable by principal component analysis.
