摘要: 鄂尔多斯荒漠草原30多年来鼠类的群落组成,由以草原黄鼠为主、长爪沙鼠次之,渐变为以长爪沙鼠为主,子午沙鼠和草原黄鼠次之。引起鼠类群落演替主要是人类经济活动的结果。动物鼠疫流行亦引起群落组成的变化,致使对鼠疫抗性较高的子午沙鼠数量渐增。动物鼠疫流行前的调查表明,4类生境中以长爪沙鼠的数量最多。鼠疫流行,引起长爪沙鼠数量从多到少急剧变化。

Abstract: In a period of 30 years, the composition of the rodent populations in Erdosi desert-grasslands has been changed from the pathern, in which Citellus dauricus possessed the first position and Meriones unguiculatus as the second, to a pathern that was Meriones unguiculatus, Meriones meridianus, and Citellus dauricus in order. The reason of the succession Were mainly the results of economic activities. The plague epizootics caused the succession, too. It made the plague resistant species such as Meriones meridianus increased. The investigation showed that Meriones unguiculatus had the largest population in 4 different habitats, and plague epizootics caused the population decreased dramatically.
