为了解长白山林区落叶松人工林节肢动物的发生规律，采用随机取样的方法，调查研究了吉林省敦化市落叶松人工林冠层的节肢动物。结果表明：落叶松人工林内落叶松球蚜和落叶松鞘蛾发生量较大；节肢动物发生量主要集中在6、7月份，8月份节肢动物群落数量和种类开始下降；面积大的林分内节肢动物群落相对较丰富，稳定性高；落叶松冠层下部节肢动物群落数量整体上高于中层和上层。

In order to find out the occurrence regularity of arthropods community on plantation of Larix olgensis Henry in Changbai mountain,we used a randomly sampling method to study the arthropods on the plantation canopy of Larix olgensis Henry in Duhua city,Jilin province.The results showed that the main species in the plots were Adelges laricis Vallot and Coleophora obducta(Meyrick);arthropod community mainly appeared in June and July,and it began to decline in August.Arthropod community of the plots of a larger area was richer and more stable than the smaller one.The number of arthropod on lower-level branch was greater than middle-level and upper-level branch.
