5·12绵竹市地震后病媒生物密度监测结果分析

5.12 Mianzhu City earthquake monitoring the density of vector analysis of biological

目的及时掌握绵竹市地震灾后病媒生物种类、密度动态,为病媒生物性疾病风险评估提供可靠依据,科学合理、及时有效的控制病媒生物,切断传染病传播途径,保护灾区人民健康。方法根据《汶川地震灾区病媒生物监测方案(试行)》要求,采用目测法监测蚊虫、蝇类密度;鼠迹法监测鼠类密度。结果绵竹市震后6-10月各监测点平均蚊虫密度为13.45只/人工.h,平均蝇类密度为0.23只/m2,平均鼠类密度为4.00处/2 000 m。结论地震后绵竹市6月、7月蚊?蝇?鼠密度较大,对灾区人民健康造成巨大隐患,8月份居民入住板房蚊?蝇?鼠密度明显下降,已达到不足为害水平。

Objective To grasp Mianzhu City earthquake vector species, density dynamics, for the vector of biological disease and provide a reliable basis for risk assessment, scientific and reasonable, timely and effective control of vector biology, cut off the route of transmission of infectious diseases, the protection of the disaster area people＇s health. Methods According to ＂earthquake - stricken Wenchuan vector biological monitoring program （ Trial ） ＂ requirements, the use of visual monitoring of mosquitoes, flies density ; rat track method to monitor the density of rodents. Results of Mianzhu City, June - October after the earthquake monitoring point average mosquito density was 13.45 / artificial hours, flies an average density of 0.23/m^2 , the average rodent density of 4.00 / 2000 m. Conclusions after the earthquake in Mianzhu City 6,7 month of mosquito, fly, the larger the population of the rodents, the health of the people in disaster areas caused enormous problems, in August the residents to move into board rooms, fly, mosquito density decreased, Have reached a level of less than harm.
