摘　　要：1992 ～1997 年, 对大理苍山洱海自然保护区山地蚤类进行了垂直分布的调查研究, 共采获蚤类5科21 属39 种(亚种) 3241 头。并对以苍山为主体的山地各主要生态环境蚤类的群落结构、物种丰富度、物种多样性、均匀度和生态优势度进行了测定和比较。分析蚤类及其宿主动物的分布特点和自然环境因素后认为,在苍山所获39 种蚤类中有16 种( 占41-03 % ) 属东洋界种类, 21 种(占53-84% ) 属古北界种类,2 种属广布种(占5-12 %) ; 在中山温凉性针阔叶混交林内海拔约3 100 m 处是该山两大动物区系分异的界线。研究认为,我国西南部横断山区两大动物区系界线的划分以海拔高度为宜, 其分界线与当地温凉性针阔混交林的分布带一致。An investigation on the fauna and ecology of fleas in the Cangshan Mountain and Erhai Lake Nature Reserve of Dali was carried out from 1992 to 1997.A total of 3241 individuals belonging to 39 species,21 genera and 5 families was collected.The species diversity,evenness and ecological dominance indices of fleas communities in 7 main ecological environments were measured and compared.According to the investigation,the stability of flea communities is the highest in the coniferous and broadleaf mixed forest and the lowest in cultivated area.The vertical distribution of 39 species of fleas was investigated on both eastern and westsern slope of Cangshan Mountain.21 species (53 84%) belong to Palaearctic realm,16 species (41 03%) belong to Oriental realm,and 2 species (6 06%) are wide spread species.The elevation of 3100 m (in Cooltemperate coniferous and broadleaf mixed forest) was the dividing line between the two realms in Cangshan Mountain.The authors cosider that delimiting the boundary line between Palaearctic and Oriental Regions in Hengduan Mountains of Southwestern China should base on the altitude,and the boundary line corresponds to the distributional band of the Cooltemperate coniferous and broadleaf mixed forest in this area.
