摘　　要：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 research the population structure and biological diversity of plague host animal in plague foci in Hebei Province,and provide evidence for the plague prevention and control. Methods Organizing the monitor data of plague host animals in plague foci in Hebei Province from 1990 to 2013,and making some statistical analysis. Results Totally,10 241 rats were caught in the investigation of host animals. Meriones unguiculatus was the dominant species accounting for 65. 3%,followed by Spermophilus dauricus accounting for 25. 5%. 1 392 rats were caught in the investigation of nocturnal rodents. Phodopus sungorus and Cricerulus barabensis were the dominant species,respectively accounting for 28. 74% and 50. 43%. Conclusion There was interannual succession between Meriones unguiculatus and Spermophilus dauricus in plague foci in Hebei Province. Phodopus sungorus,Cricerulus barabensis and Phodopus riborovskii were the dominant species of nocturnal rodents. The occurrence and spread of the plague is closely related to the population structure and density of host animals.
