摘　　要：2003年6月—2006年9月,对长白山自然保护区北坡的蛾类做了较全面的调查,共采集蛾类24科,445种,其中夜蛾和尺蛾是保护区内的优势类群,各林带均有分布的种共13种。随海拔的升高类蛾的多样性指数明显降低,其中红松阔叶林带蛾类的物种丰富度、个体数量和多样性指数都最高。苔原带物种丰富度、个体数和多样性指数最低,多样性指数与丰富度和均匀度相一致,相关系数都大于0.9。而不同林带间的蛾类相似性系数很低。An overall investigation was conducted to study the moth diversity in the northern slope of Changbai Mountain Nature Reserve during June 2003 and September 2006. A total of 445 species belonging to 24 families was collected, among which Nootuidae and Ceometridae are dominant groups and 13 species are common to every forest zone. The moth diversity obviously decreases with increasing elevation, and the diversity index, species richness and individual number of Korean pine broad-leaved forest are the highest, and those of alpine zone are the lowest. The diversity index is accordant with species richness and evenness index, and their correlation coefficients are all more than 0.9, while the similarity coefficient of species is very low between different zones.
