摘　　要：为研究小兴安岭天然次生林蛾类群落组成结构及多样性季节动态,2019年和2020年6-9月,通过灯诱法对蛾类群落进行系统调查。共采集蛾类样本14 396个,分属23科439种,夜蛾科、螟蛾科、尺蛾科、灯蛾科为优势类群;不同时期蛾类群落均为中等不相似或极不相似,优势种组成具有极大的差异,各时期群落特有种均较多;蛾类物种多样性指数和均匀度指数均在8月下旬达最大值,丰富度指数在7月中旬达最大值;全年群落种-多度分布为对数正态分布,各季节仅7月中旬和8月下旬为对数正态分布,其他时期均为对数级数分布。天然次生林蛾类群落组成和多样性季节差异较大,群落结构随季节变化通过自我调节达到动态平衡。To study the community composition and seasonal dynamics of moth diversity in the natural secondary forests of the Xiaoxing'an Mountains,a systematic survey of the moth community was conducted from June to September in 2019 and 2020 using light traps.A total of 14,396 moth specimens were collected,belonging to 439 species from 23 families.The Noctuidae,Pyralidae,Geometridae,and Arctiidae were the dominant families.The moth communities during different periods were moderately or highly dissimilar,with significant differences in the dominant species composition.Each period had a relatively large number of unique species.The moth species diversity index and evenness index reached their maximum values in late August,while the richness index peaked in mid-July.The annual community species-abundance distribution was log-normal,while in individual seasons only mid-July and late August followed a log-normal distribution,and other periods followed a log-series distribution.The composition and diversity of the moth community in the natural secondary forests showed significant seasonal variations,with the community structure dynamically balancing through self-regulation.
