摘要：2011年5月至11月對南京曉莊學院楊樹林3個樣地的蛾類資源進行調查。共收集蛾類 1249 只,隸屬于 13 科、 62 屬、69種。應用Shannon-Wiener多樣性指數、均勻度、優勢度、豐富度、相似性系數等分析了南京曉莊學院地區不同季節蛾類的多樣性。隨著時間的變化，各月份蛾類組成及數量差異較大,數量為9月>5月>10月> 11月，Shannon-Wiener多樣性指數、均勻度、優勢度、豐富度均為9月>5月>10月> 11月。對監測點的蛾類多樣性研究發現，Shannon-Wiener多樣性指數、均勻度、豐富度均為C點>B點>A點，而優勢度為A點=B點<C點,相似性系數為BC點>AB點>AC點。

結果表明: 季節性變化明顯、植物群落及生態環境的差異是導致蛾類群落結構差別的主要因素。南京曉莊學院地區蛾類種群動態有明顯的時序變化, 這種變化在很大程度上與季節性的溫度變化有關。

Abstract：On May to November2011 we have investigated moths in three samples of poplars in Nanjing Xiaozhuang college. The results indicated that a total of 1249 mothswere collected, belonged to 13families, 62 genera, and 69 species. Application Shannon-Wiener diversity and evenness index, dominance index, specific richness and coefficient of similarity such as the nanjing xiaozhuang college season are different in the moth diversity. As the change of time, each month moth composition and the difference in the number, number for September > May > October >November, Shannon-Wiener diversity and evenness index, dominance index, specific richness was September > May >October >November. The moth diversity of monitoring stations, the study found Shannon-Wiener diversity index, evenness index and specific richness was C > B > >A point, However the evenness index  showed point A= point B <C point, the similarity analysis  was BC point >  AC point >AB point.

The results show that seasona changed significantly. The differences of moth community structureweremainly resulted from the differences plantcommunity structures and ecological environment in Yangshulin.They affected the moth community structure and dynamics . Moth population dynamics in NanJing Xiaozhuang college had visible timing changes , which might be related to the seasonal temperat- ure changes.Key words：The moths, Diversity , Season, Poplar grove, community
