摘　　要：目的了解北京市房山区"7.21"水灾后病媒生物密度情况、水灾对病媒生物密度的影响,为灾后媒介生物性传染病的防控提供依据。方法蚊密度监测采用二氧化碳诱蚊灯法,蝇密度监测采用目测法,鼠密度监测采用鼠夹法。结果房山区"7.21"水灾后平均蝇密度为3.48只/m2,蚊密度为2.05(只/灯·小时),鼠密度为0.42%。蚊密度低于常年监测水平,但差异无统计学意义(t=-1.501,P=0.194),鼠密度低于常年监测水平,差异有统计学意义(t=-3.035,P=0.029)。结论蚊蝇鼠总的密度较低,根据病媒生物的监测结果,指导灾后病媒生物的综合防治,降低媒介生物性传染病的暴发与流行。Objective To estimate the impact of the ＂7.21 ＂ flood in Fangshan District of Beijing on vectors densities, and to provide the evidence for prevention and control of vector-borne diseases. Methods CO2 Mosquito trapping lamp method, visual observation and rat clamp method were used to monitor the density of adult mosquitoes, flies and rats respectively. Results The densities of mosquitoes, flies and rats reached 2.05 pieces per lamp-hour, 3.48 per square meter and 0.42 percent respectively. Although mosquito density was lower than annual average level, there was no significant difference between them （t = -1. 501 ,P = 0. 194）. Rat density was also lower than average level and the difference was significant （t -- -3. 035, P = 0. 029）. Conclusion The overall densities of mosquitoes, flies and rats were generally low. Scientific and systematic surveillance of vectors played a guiding role in the control and prevention of vector-borne diseases, and also reduced related diseases outbreak.
