目的掌握2005-2007年通化市肾综合征出血热宿主动物种群及其数量变化规律,为制定防控措施提供科学依据。方法2005-2007年在通化市选择城镇居民区、特殊行业、农村自然村3种生境,按全国统一的监测方案,采用鼠夹法每月监测1次。3种生境各布200夹次,对捕获鼠标本登记、鉴定鼠种,计算鼠密度。结果2005-2007年共捕鼠2 151只,隶属1科3属4种,优势种为褐家鼠。3种生境平均鼠密度为5.37%,其中农村自然村7.44%,城镇居民区4.64%,特殊行业4.10%,均在春秋两季出现高峰,发病曲线呈现5月、11月双峰型。结论通化市农村自然村鼠密度最高,其次为城镇居民区,特殊行业。3种生境优势种均为褐家鼠,鼠密度的消长趋势与人群发病基本一致。 Objective To master the population dynamics of host animal population and its quantitative changes of hemorrhagic fever with renal syndrome in Tonghua City from 2005 to 2007 and provide a scientific basis for the development of prevention and control measures. Methods From 2005 to 2007, three kinds of habitats in urban residential areas, special industries and rural natural villages were selected in Tonghua City. According to the national unified monitoring plan, the mouse clamp method was used to monitor once a month. Three kinds of habitats each 200 times, the capture of the mouse registration, the identification of species, calculation of mouse density. Results A total of 2 151 trapping mice were collected from 2005 to 2007, belonging to 1 genera, 3 genera and 4 species. The dominant species was Rattus norvegicus. The mean rodent density of the three habitats was 5.37%, of which 7.44% in rural natural villages, 4.64% in urban residential areas and 4.10% in special industries, both of which peaked in spring and autumn. The incidence curve showed bimodal patterns in May and November. Conclusion The density of rats in rural natural villages in Tonghua City is the highest, followed by urban residential areas and special industries. The predominant species of three habitats were Rattus norvegicus, the trend of growth and decline of rodent density was basically consistent with the crowd incidence.
