目的掌握中哈边境口岸大沙鼠种群密度分布动态特征,为监测及预警提供依据。方法在鼠疫监测点采用生态学路线洞群法调查大沙鼠种群密度、生境分布;用间接血凝试验、反向血凝试验、ELISA、四步分离法进行鼠疫血清F1抗体、抗原及病原体检测。结果大沙鼠种群在边境口岸四大生态区洞群平均覆盖率为29.7%,洞群密度8.9/hm2,洞群栖息率33.2%,鼠密度10.5/hm2。大沙鼠在入境通道的传入,边界的迁入、窜出,构成疫情传入的因素。结论新疆中哈边境区大沙鼠种群密度高,应高度警惕大沙鼠鼠疫疫情发生。
Objective To grasp the dynamic characteristics of population density distribution of gerbil in the border between China and Kazakhstan, and to provide the basis for monitoring and early warning. Methods The population density and habitat of gerbils were investigated in the plague plague area by using ecological corridor method. The serum F1 antibody, antigen and pathogen were detected by indirect hemagglutination test, reverse hemagglutination test, ELISA and four-step separation method . Results The average coverage rate of gerbil population in the four ecotopes at the border crossings was 29.7%. The population density of the population was 8.9 / hm2. The population habitat of the population was 33.2%. The rat density was 10.5 / hm2. Inhabitants of large gerbils inbound into the border, the immigration, sprang, constitute the incoming epidemic factors. Conclusion The population density of gerbils in the Sino-Kazakh border area of Xinjiang is high, and vigilance should be paid to the occurrence of the plague in rats.
