摘要为研究小兴安岭阔叶红松林蛾类群落组成结构及季节动态，2013年和2014年6—9月份，通过灯诱法对阔叶红松林蛾类群落进行系统的调查。共采集蛾类样本8 919头，分属26科394种，夜蛾科和尺蛾科为优势类群；不同时期蛾类群落相似性均为极不相似，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丰富度均在夏季达最大值，均匀度指数在秋季达最大值，多样性指数与丰富度指数时间变化趋势为显著的正相关；种-多度分析表明，除生长季末期外均表现为对数正态分布。凉水自然保护区阔叶红松林生态系统蛾类群落组成季节差异较大，群落结构均较为稳定，环境条件较为优越。

The moth community was investigated by light trap in June to September 2013 and 2014 to reveal the community structure and seasonal dynamic of moths in broad leaved Korean pine forest of Xiaoxing’an Mountains. A total of 8 919 specimens were collected, belonging to 394 species, 26 families. Noctuidae and Geometridae were the dominant taxa, but both of them have great difference in different periods. The similarity of moth communities in different periods was very different, and dominant species composition had a great difference, the proportion of community specific species was larger in each period. In time series, the species diversity index was significantly positively correlated with the richness index. The species abundance distribution of the moth community was in accordance with the lognormal distribution, except for the end of the growing season. The moth communities in the broad leaved Korean pine forest ecosystem in Liangshui Nature Reserve are more stable, and the environmental conditions are superior.

阔叶红松林是小兴安岭的地带性森林植被，是温带针阔混交林的典型代表。鳞翅目是昆虫纲中第二大目[1]，分布极为广泛，作为主要植食性昆虫类群之一，在森林生态系统食物营养网络体系中，与植物群落有着极为密切的关系，同时也是捕食性物种的重要食物来源，在食物链中起重要作用，是生态系统物质循环和能量流动中的重要环节[2]。昆虫群落结构和动态能及时准确地反映森林环境的变化[3]，研究蛾类的动态规律，及时应用于森林环境的保护和监测，有利于合理地利用和保护森林资源[2]。……
