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．
