摘要
2015年5-8月对河北省辽河源自然保护区灯下蛾类及主要种类的发生情况进行了调查,获得标本21科417种1539头.其季节发生情况是:尺蛾科在整个调查期内处于优势;灯蛾科为5月份优势种;夜蛾科为6、8月份优势种;尺蛾科在7月份发生数量较大.结果显示,该保护区蛾类发生以5月最低,7月最高,各月份间差距不大;该保护区的蛾类群落多样性指数与均匀度不一致,群落的种—多度关系接近于对数正态分布模型,说明该保护区的生态环境良好.
The moths and their main species were investigated in the Liaoheyuan nature reserve in Hebei province in 2015 and 1539 moths from 417 species in 21 families were obtained. Geometridae was always the dominant family throughout the investigation period. Arctiidae was the dominant specie at May. Noctuidae was the dominant specie at June and August. Geometridae had a large number of occurrence in July. The results showed that,the occurrence of moths was at the lowest in May and highest in July,and didn＇t varied a lot among those months. The diversity index of moth community was not consistent with evenness,and the species abundance relationship served the logarithmic normal distribution models. Therefore,the environmental conditions of Liaoheyuan Nature Reserve was good.
