摘要: 1987年6-9月用标志重捕流放法在呼和浩特地区对黑线仓鼠的巢区进行了研究,雌、雄性的巢区分别为2720.6±576.O平方米和7684.1±1736.6平方米,活动距离分别为95.5±l4.4米和135.9±12.4米。黑线仓鼠巢区和活动距离季节变化不明显,雄鼠巢区6-9月全部重叠,雌鼠巢区只有9月份不重叠,雌、雄性巢区彼此重叠。

Abstract: From June to Spetember 1987 home range of striped hamster were estimated by
mark and release trapping in Huhehaote district,Nei Mongo1.The trapping grid covred anareaof 4 ha,and consist of 400 points,10cm apart,with 1 trap at each point·This field work was done from lth to 1oth every month.The material consisting of a total of 627 captures for 106 individuals was collected.
The study showed using inclusive boundary strip method the areas of home range were calculated,5 trapping times Were reasonable.The areas of home range and movement distance of Striped hamster were shown in table 1.
Home range of male adults are larger than those of femalesfrom June to September .Theareas of male adults increasing (Tab.3) in that time andwas the largest in september due to reproductive activites.On the other hand, that of female were decreased and it was the smallest in September.
Home ranges of individuals are often overlapped each other in different sexes and ages in July and August,but did not in female adults in September.
