【摘要】 北京市1985～1995年开展家鼠鼠情监测。结果：有褐家鼠、小家鼠两种，前者为农村优势种，后者为城镇优势种。每年有两个数量高峰（2～4月、9～11月）；自1986年以来开展大规模灭鼠活动，并未改变此规律，但使家鼠密度显著下降。近几年斑疹伤寒发病率大大降低。更多还原

Theyare Rattus norvegicus and Mus musculus. The former isdominant in rural, the latter is dominant in urban. It showed that there are two density peaks for both commensal rodent (between February-April andSeptember-November). Since 1986, the regularity has not changed because of extensive commensal rodent control campaign which has made the density of commensal rodent to decline obviously.
