摘　　要：198 5～ 1991年期间 ,我们多次对云南泸水高黎贡山森林脑炎疫源地宿主动物进行了调查 ,共捕获小型兽类 75 0只 ,它们隶属 4目 9科 15属 2 4种。其中 ,优势种为中华姬鼠 A.draca( 2 4 .0 3 % )、克钦绒鼠 E.cachinus( 2 3 .0 5 % )和社鼠N.conifucianus( 19.16% )。根据垂直调查的结果看出 ,小兽的密度、物种多样性和均匀度都以森林植被条件较好的中山森林地带的湿性常绿阔叶林和温凉性针阔叶混交林带为高。经分析认为中华姬鼠、克钦绒鼠和社鼠在我省西部山地作为森林脑炎宿主动物具有较大的流行病学意义。The small mammal hosts for Russian spring-summer encephalitis (RSSE) had been investigated in the RSSE nature foci in the Mt. Gaoligong of Lushui County in Yunnan Province from 1985 to 1991. The 750 speciemens were trapped, belonging to 24 species, 15 genera, 9 families, 4 orders, which the dominant species were A. draca(24.03%), E.cachinus(23.05%) and N.conifucianus(19.16%). According to the results of the vertical investigation, the small mammal density, the diversity and evenness index were the higher of the wet evergreen broadleaf forest and the cool-temperate coniferous and broadleaf forest. It was concidered that A.draca, E.cachinus and N.conifucianus as the hosts of RSSE play an important role in epidemiology.
