摘　　要：为了研究小兴安岭地区处于森林恢复期的典型人工林与原始林昆虫群落的结构,对位于凉水自然保护区的4种典型林型的昆虫群落进行了系统调查.共采集昆虫标本11712号,隶属于10目81科293种,其中膜翅目、双翅目、鞘翅目为优势类群.对不同林型昆虫群落稳定性分析得知,落叶松人工林和原始阔叶红松林昆虫群落结构相对于其他林型更为稳定.主分量分析表明,各林型中捕食性昆虫和中性昆虫对昆虫群落稳定性发挥着关键性作用,增加捕食性昆虫种类和数量能增强昆虫群落的稳定性.昆虫群落的极点排序表明,红松人工林和原始阔叶红松林环境差异相对较小.In order to study the insect community structure of typical artificial and primeval forests during different restoring stages in Xiaoxing＇ an Mountains, we had systematically investigated the insect communities of four typical forests in Liangshui Natural Reserve. A total of 11712 specimens of 293 species were collected, which belonged to 81 families of 10 orders, with Hymenoptera, Dip- tera, and Coleoptera being the dominant groups. The community stability analysis on insect commu- nities showed that the insect communities of Dahurian larch plantation and original broadleaved Ko- rean pine forest were more stable than other forest types. The principal components analysis indica- ted that predatory and neutral insects played important roles in the community stability which in- creased with the increasing predatory insect species and quantities. Polar ordination analysis showed that there was little difference between the environmental factors of Korean pine plantation and the original Korean pine forest.
