摘要
采用笼养饲喂法、野外个体颊囊内含物统计法和胃内含物分析法 3种方法 ,于 1 997年对内蒙古鄂尔多斯沙地中的 4种主要啮齿动物 (小毛足鼠 Phodopus roborovskii、三趾跳鼠Dipus sagitta、子午沙鼠 Meriones meridianus和黑线仓鼠 Cricetulus barabensis)的食性进行了研究 .3种方法得出的结果基本一致 .从胃内含物和颊囊内含物分析结果看 ,小毛足鼠和黑线仓鼠主要以各种植物种子和昆虫为食 ;从饲喂结果看 ,也主要以种子为食 (因在饲喂时未喂昆虫 ) ,并以含水量高的绿色植物体补充水分 .三趾跳鼠主要以绿色植物体为食 ,其次为植物种子(主要是牧草种子 ) .子午沙鼠的食性则介于三趾跳鼠与小毛足鼠 (和黑线仓鼠 )之间 ,对种子的喜食程度类似于三趾跳鼠 。
Food habits were studied for four dominant rodents ( Phodopus roborovskii, Dipus sagitta, Meriones meridianus and Cricetulus barabensis ) inhabiting in Ordos sandland, NeiMongol in 1997. The results obtained by three methods of feeding experiments, analysis of cheek pouch contents, and analysis of stomach contents showed no significant differences basically. Phodopus roborovskii and Cricetulus barabensis feed mainly on various plant seeds and insects according to the analysis of cheek pouch contents and stomach contents; plant seeds are also primary foods of them and high water content green plants are needed to replenish water in feeding experiments. Dipus sagitta feeds on green plants and herbage seeds primarily. The food preference of Meriones meridianus is similar to Dipus sagitta on plants and seeds, while on seeds is similar to Phodopus roborovskii and Cricetulus barabensis.
