[目的]为了解地震后鼠密度和蚤指数的变化规律,为地震灾后鼠疫的防治提供依据。[方法]从云南省1982～2008年地震资料中选取3级以上地震,在地震震中位置选取地震前1个月及地震后24个月黄胸鼠鼠密度和印鼠客蚤蚤指数,观察其变化趋势。[结果]地震后第1个月的鼠密度最高,从第3个月开始总体呈逐渐下降趋势,在震后23个月降到最低,24个月有回升趋势;地震后1个月蚤指数开始上升,在20、21、22个月最高,其次为2、4、8、15、19、23、24个月,震后6、14个月最低,低于地震前。[结论]地震引起鼠密度和蚤指数的波动,鼠密度总体呈现下降的趋势,蚤指数的波动大,总体下降的趋势不明显。两者均在地震发生初期有较大上升。
[Objective] The study aimed to understand the rule of rat density and flea index after earthquake and provide basis for the prevention and control of plague after earthquake. [Method] The earthquakes of magnitude 3 and above were selected from the seismic data of 1982 ~ 2008 in Yunnan Province. The density of rodent rat and the flea flea index of rats were selected 1 month before the earthquake and 24 months after the earthquake at earthquake epicenters Trend. [Result] The rodent density in the first month after the earthquake was the highest, decreasing gradually from the third month to the lowest after 23 months and rising again in 24 months. The flea index at 1 month after the earthquake It started to rise at the highest in 20,21,22 months, followed by 2,4,8,15,19,23,24 months, the lowest in 6,14 months after the earthquake and lower than before the earthquake. [Conclusion] The earthquake caused the fluctuation of rat density and flea index, the overall density of rat showed a decreasing trend, the flea index fluctuated greatly, and the overall decline trend was not obvious. Both of them have a great rise in the early period of the earthquake.
