目的通过对河北省鼠疫疫源地内宿主动物种群结构和生物多样性变化研究,为动物间鼠疫防控提供参考。方法整理1990-2013年河北省鼠疫疫源地宿主动物调查监测数据,利用统计学方法分析。结果主要宿主动物调查共捕获鼠类10 241只,长爪沙鼠处于优势地位占65.3%,达乌尔黄鼠占25.5%。夜行鼠调查共捕鼠1 392只,其中黑线毛足鼠和黑线仓鼠为优势种群,分别占28.74%和50.43%。结论河北省鼠疫疫源地内长爪沙鼠和达乌尔黄鼠种群在年际间存在演替,夜行鼠优势种群以黑线仓鼠和黑线毛足鼠为主,转化为黑线仓鼠、黑线毛足鼠和小毛足鼠,鼠疫宿主动物种群结构及密度与动物间疫情发生明显相关。
Objective To study the changes of the population structure and biodiversity of plague foci in Hebei Province and provide a reference for the prevention and control of plague in animals. Methods The survey data of host animals in plague origin in Hebei Province from 1990 to 2013 were collected and analyzed by statistical methods. Results A total of 10 241 rodents were captured in the host animal survey, 65.3% of them were dominant and 25.5% of them were Daurian ground squirrels. In the night-time rat survey, a total of 1 392 cats were caught, of which black-footed hamster and black-hamster were the dominant species, accounting for 28.74% and 50.43% respectively. Conclusion The population of Meriones unguiculatus and Daurian ground squirrel in the plague foci of Hebei province had succession in the interannual period. The predominant population of nocturnal rats was dominated by black line hamster and black line hairs, converted to black line hamster, black The structure of the host animal and the density of the plague fauna were significantly related to the epidemic situation among the animals.
