摘　　要：紫金山不同植被类型夏季蛾类分别隶属于10总科24科253属338种。应用多样性、均匀度、优势度等指标对不同植被类型蛾类的群落结构以及时间动态进行了分析。结果表明:夏季是紫金山蛾类的主要发生时期,紫金山蛾类昆虫较为丰富,蛾类的种类、数量与生境的复杂程度呈正相关;植物群落及生态环境的差异是导致蛾类群落结构差别的主要因素,蛾类可作为环境变化的指示物种;各植被类型的优势种差异较大,相似性系数处于中等不相似水平;多样性指数不受均匀度影响,说明紫金山针阔混交林、针叶林、竹林等植物群落正处于演替的某个中间阶段;不同时期蛾类的结构组成和多样性存在明显差异,优势种群季节性变化显著。The index of diversity, evenness and dominance were used to analyzed the community structure of moth and its dynamic in summer in different vegetation types in Zijin Mountain, Nanjing. The results showed that moths were belonged to 10 total families, 24 families, 253 genera and 338 species in this areas. The main occurred time of moths was in summer in Zijin Mountain and the species and quantity of moth were positively correlated to its habitat. The vegetation types and ecological environment were the main reasons resulted in the differences of moth community structure and thus moths could be as an indicator for environmental changes. That the diversity index was not changed with the evenness index indicated that the conifer and broadleaf mixed forest, the coniferous forest and the bamboo forest in Zijin Mountain were in some middle stage of succession. The structure composition and muhiplicity of moth existed obvious difference in different time. The seasonal changeof superiority population was remarkable.
