摘要
本文对康保鼠疫自然疫源地的植被类型、宿主动物的地理分布、鼠疫媒介的种类组成及其相互间的关系进行了系统的调查,发现达乌尔黄鼠和长爪沙鼠的地理分布交错而不重迭;小形啮齿动物的广泛分布和媒介的多寄主性,在疫源地中起到种间或种内各群落间的连接和沟通作用;结合流行病史资料分析表明:该疫源地仍有长期保菌和再次发生鼠疫流行的可能。
The paper reported the result of the investigation on the vegetation type, geographical distribution of host animals, population and composition of plague vectors and their interrelation in the Kang—Bao plague natural foci. It was found that the geographical distribution of Citelus dauricus and Meriones unyuiculatus is crisscross, but don't overlap, the wide distribution of the small size rodents and the poly-host character of the vectors play a link role between two habitats of the different reservoirs or two type communities in the nafural foci. The result of analysis to the epizootic history show that it ispossible to preserve Y. pestis for long time and plague epidemic again in this a rea.
