摘要
本文对大兴安岭东南部草原的达乌尔黄鼠及寄生蚤的垂直分布与鼠疫流行病关系进行了初步研究。随着海拔高度的增加，黄鼠数量逐渐减少，其方形黄鼠蚤松江亚种无论体蚤还是巢蚤所占比例随之减少，黄鼠鼠疫和人间鼠疫流行的年次亦随之减少。而方形黄鼠蚤松江亚种与达乌尔黄鼠的有鼠样方率呈显著的正相关（γ巢＝０．９５４９，Ｐ＜０．０１；γ体＝０．９３０５，Ｐ＜０．０１）。阿巴盖新蚤与方形黄鼠蚤松江亚种所占比例状况截然不同，该蚤所占比例与达乌尔黄鼠的有鼠样方率呈显著负相关（γ巢＝－０．９５１４，Ｐ＜０．０１；γ体＝０．９４４９，Ｐ＜０．０１）
This paper presents our primary study of the relationship between the
vertical distribution of Citellus dauricus and its parasitic fleas and plague epidemics in
southeastern grasslands of Daxing'anling mountains.With the raising of the sea level,the result
has showed that the numbers of Citellus dauricus gradually decrease and the proportion of
parasitic flea and nest flea of Citellophilus tesquorum sungaris in the fleas population gradually
decrease;plague epidemics gradually decrease too per year.The proportion of C.t.sungaris
among the flea population is bound up with that of positive sample fields of Citellus dauricus
P<001;(parasitic)=09305,P<001],while is negatively bound up with in Neopsylla
abagtui(parasitic)=09449,P<001].
