摘　　要：系统调查了凉水自然保护区封山育林状态下云杉人工林蛾类群落,结果表明:共捕获蛾类样本17 313只,隶属于23科450种,夜蛾科为优势类群,豆卷叶野螟、稠李巢蛾、苹果巢蛾和一色兜夜蛾为优势种;多样性指数与均匀度指数季节动态变化趋势相一致;种—多度分布符合对数正态分布模型;不同季节群落优势种组成差异极为显著,优势种组成仅7月中旬与全年群落特征相同;群落种—多度分布仅为7月中旬和8月末与全年群落特征相同。An investigation on the diversity of moth community was carried out in Picea asperata plantation of Liangshui nature reserves, Xiao Xing＇an Mountains. A total of 17 313 specimens were collected, belonging to 450 species, 23 families. Noctuidae was the dominant family. Sylepta ruralis, Yponomeuta evonymellus, Yponomeuta padella and Cosmia unicolor were the dominant species. Significant correlation was found between indices of diversity and evenness. The curve of the moth species-abundance was in accordance with the log-normal hypothesis. Dominant species composition showed very significant difference in different seasons, and only in mid July, the results show that the dominant species was the same as the entire investigation period community characteristics. Only in mid July and late August 24, the curve of species-abundance was the same as the entire investigation period community characteristics.
