锡林郭勒草原啮齿动物群落结构特征

Community Structure of Rodent in Xilingol Steppe

2011~2013年采用铗日法对二连浩特市、苏尼特左旗、苏尼特右旗、锡林浩特市和东乌珠穆沁旗5个典型监测点的啮齿动物群落结构进行了调查,结果表明：三年中共布铗16850铗日,捕鼠582只,分属5科13种。5个监测点的啮齿动物群落结构具有差异,总捕获率二连浩特市〉锡林浩特市〉东乌珠穆沁旗〉苏尼特左旗〉苏尼特右旗。锡林浩特市和二连浩特市的物种数均为9种,东乌珠穆沁旗为7种,苏尼特右旗和苏尼特左旗均为6种。群落多样性指数锡林浩特市〉二连浩特市〉苏尼特右旗〉苏尼特左旗〉东乌珠穆沁旗。

From 2011 to 2013,rodent community were surveyed using snap-traps in five typical monitoring sites,i.e.Erlianhaote,Sunitezuo Banner,Suniteyou Banner,Xilinhot City and Dongwu Banner.The results showed that 16850 traps were put,and a total of 582 individuals which belonged to 5family 13 species were captured in three years.Community structures of rodent were different among five typical monitoring sites.The order of total capture rate of rodent was Erlianhaote〉 Xilinhot〉 Dongwu Banner〉 Suniteyou Banner〉 Sunitezuo Banner.Rodent community had nine species in Xilinhot City and Erlianhaote City,seven species in Dongwu Banne,and six species in Suniteyou Banner and Sunitezuo Banner.The order of community diversity was Xilinhot City 〉Erlianhaote City〉 Suniteyou Banner〉 Sunitezuo Banner〉Dongwu Banner.
