摘要為研究小興安嶺闊葉紅松林蛾類群落組成結構及季節動態，2013年和2014年6—9月份，通過燈誘法對闊葉紅松林蛾類群落進行系統的調查。共采集蛾類樣本8 919頭，分屬26科394種，夜蛾科和尺蛾科為優勢類群；不同時期蛾類群落相似性均為極不相似，優勢種組成具有極大的差異，各時期群落特有種均較多；蛾類物種多樣性指數和豐富度均在夏季達最大值，均勻度指數在秋季達最大值，多樣性指數與豐富度指數時間變化趨勢為顯著的正相關；種-多度分析表明，除生長季末期外均表現為對數正態分布。涼水自然保護區闊葉紅松林生態系統蛾類群落組成季節差異較大，群落結構均較為穩定，環境條件較為優越。

關鍵詞蛾類；群落結構；多樣性；種-多度分析

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.

闊葉紅松林是小興安嶺的地帶性森林植被，是溫帶針闊混交林的典型代表。鱗翅目是昆蟲綱中第二大目[1]，分布極為廣泛，作為主要植食性昆蟲類群之一，在森林生態系統食物營養網絡體系中，與植物群落有著極為密切的關系，同時也是捕食性物種的重要食物來源，在食物鏈中起重要作用，是生態系統物質循環和能量流動中的重要環節[2]。昆蟲群落結構和動態能及時準確地反映森林環境的變化[3]，研究蛾類的動態規律，及時應用于森林環境的保護和監測，有利于合理地利用和保護森林資源[2]。……
