| 摘 要： | 通过为期一年的标志重捕研究，获得了农田优势种黑线姬鼠与臭聃的巢区、活动距离、领域性等资料，分析了种间领域性及空间分布的关系。并观察到随着捕获突数增多，对动物的可捕性产生影响，再结合对重捕期体重变化的分析，发现长期标志重捕对两种动物产生了正与负的效应。

| Abstract: | Some ecological dataof Apodemus agrarius and suncuns murinus were obtained from a mark-recapture method carried on the farmland between Nov.,1986and Oct.,1987,The average home range size of A agrarius was 2271±204．1m2 for males and 1841±183.1m2 for females．There was no territoriality in males．but females showed some evidence of territoria1ity．The home range size of males of Suncusmurinus averaged 1227±263.Om2 ，and that of females 241.4±50.3m2 ．However、no territoriality was found in the shrews．
The two species showed overlap in their home Tanges although the areas preferred by A ．agrarigs seldom ovetlapped those preferred by S．murinus.A.agrarius was confirmed to be capture-prone．The mean body weight of A ．agrarius did not change significantly within one retrapping period (10 days)，but S.murinus showed a decrease of body weight due to marking and capturing． |
