南京紫金山春季蛾类多样性研究

采用灯诱的方法对紫金山4种不同植被类型鳞翅目蛾类资源进行了调查.共收集蛾类1182只,隶属于9总科、21科、155属176种.应用Shannon-Wiener多样性指数、均匀度、优势度、相似性系数等分析了紫金山不同植被类型蛾类的多样性.结果表明:紫金山阔叶林蛾类多样性较高,种类较丰富;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.蛾类多样性指数不受均匀度影响.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.

Study on Moth Diversity in Spring in Zijin Mountain, Nanjing

The moth resources and its diversity were investigated and analyzed by Shannon-Wiener index,evenness index,dominance index,and similarity coefficient in four vegetation types in Zijin Mountain Nanjing.The results indicated that a total of 1 182 moths were collected,belonged to 9 total families,21 families,155 genera,and 176 species.The moth diversity and genera in broad leaved forest were greater than that in coniferous and broad leaved mixed forest,coniferous forest and bamboo grove which were in some middle stage of succession.The moth diversity index was not changed with evenness.The differences of moth community structure were mainly resulted from the differences plant community structures and ecological environment in Zijin Mountain.Therefore the moths could be an indicative species for environmental change.
