辽宁鼠疫自然疫源地系我国达乌尔黄鼠鼠疫自然疫源地的边缘地带。就其地理景观,可分为黄土丘陵台地干草原与西辽河风沙草原两种类型。鼠疫流行已终息三十余年。由于多年坚持开展以黄鼠为重点的灭鼠工作,及人们的社会经济活动,使疫源地发生很大变化。植被与鼠类的演替,是变化的重要标志。这种演替促进了疫源地的健康化乃至使鼠疫逐步得到根除。

Its geographical landscape can be divided into loess hilly terraces steppe and West Liaohe wind sand grassland two types. Plague epidemic has been the end of more than thirty years. Due to many years of persistent rodent control focusing on gopher, and people’s social and economic activities, great changes have taken place in the foci. The succession of vegetation and rodents is an important indicator of change. This success has promoted the health of the foci and eventually eradicated the plague.
