摘　　要：目的研究滇南山地小区小兽及其体表蚤类群落结构。方法于1997、1998、2001、2004年对滇南山地8个县(市)的现场抽样调查,用群落生态学中的物种丰富度(S)、Shannon-Wiener多样性指数(H′)、均匀度(J′)及生态优势度指数(C′)等方法进行测定。结果共捕获小兽3184只,隶属于4目5科13属21种。黄胸鼠、卡氏小鼠、锡金小鼠、褐家鼠、大臭鼩、斯氏家鼠及针毛鼠为优势小兽;从小兽体表共采集蚤类1767匹,隶属于5科13属15种,印鼠客蚤、伍氏病蚤及缓慢细蚤为优势蚤种。结论滇南山地的蚤类分布较少,生物多样性相对于其他区域低。Objective To investigate the community structure of fleas on small mammals in eight counties of southern mountainous areas in Yunnan. Methods Small mammal hosts were captured from eight counties selected randomly in southern mountainous areas and fleas were collected from the body surface of each host. Richness （S）, Shannon- Wiener＇s diversity index （H＇）, evenness （J＇） and dominance index （C＇） were used to measure the community structure of fleas on the hosts. Results There were 3184 small mammals captured, which belonged to 21 species,13 genera, 5 families and 4 orders. A total of 1767 fleas were collected from the small mammal hosts and were classified into 15 species, 13 genera and 5 families. There were seven dominant small mammals like Rattus tanezumi, Mus caroli, M.pahari, R.norvegicus, Suncus murinus, R.rattus sladeni and Niniventer fulvescens, and the dominant fleas were XenopsyUa cheopis, Nosopsyllus （Nosopsyllus） wualis and LeptopsyUa segnis. Conclusion There are few fleas in the southern mountainous areas of Yunnan which biodiversity is lower than that in others.
