摘　　要：本文采用Lloyd提出的平均拥挤度M~*、聚集性指数M~*/M及Iwao的平均拥挤度与种群密度之间直线回归方程M~*=α+βM,用IBM计算机处理,分析了城市灭鼠达标后,连续18个月内残存鼠在住宅建筑物内的空间分布格局。结果观察到:①住宅建筑物间的残存小家鼠、褐家鼠、黄胸鼠的个体呈聚集分布;②三种残存家栖鼠都以个体群呈聚集型空间分布格局。根据目前残存鼠的空间分布格局及在时间序列上的平均密度,对正确制订灭鼠措施、选择投药位置、毒饵剂量与剂型,具有重要的参考价值。By using mean crowding(M~*), cluster index(M~*/M) from Lloyd and equation of regressive line between mean crowding and population density M~*=α+βM from Iwao, and with help of IBM computer, the spatial pattern of the population of urban remnant rodent during 18 successive months after attaining urban rodent calamity free level has been analysised. The result shows(1)Remnant Mus musculus, Rattus norvegicus amd R. flavipectus among dwelling building are in cluster distribution; (2)The three species of remnant indoor rodents have cluster spatial pattern of their population in the way of individual group, which is different from Apodemus agrarius in fields. the research on the spatial pattern of urban remnant rodent and mean density versus time order is significant to taking rodent control measure correctly, selecting proper position for poisonous bait putting, and deciding on the poison amount style, etc.
