【摘要】 2005—2007年,利用网捕、灯诱、陷阱方法采集昆虫标本,研究长白山苔原带昆虫群落的区系组成.结果显示:在322种昆虫中,鳞翅目(Lepidoptera)物种数达到了44.72%,鞘翅目(Coleoptera)、膜翅目(Hymenoptera)物种数也都超过了总数的10%.苔原带昆虫以古北-东洋区和古北区的数量占优势,都超过了总数的40%.在我国的昆虫区系成分中,苔原带昆虫地理分布可分为61个类型,其中,东北区的物种数最多,占到总数的14.69%;其次是在我国7个区都有分布的物种,占物种总数的13.64%.在起源上,长白山苔原带昆虫与国内黑龙江相同种类较多,为65.38%,其次是辽宁、河北;在国外,与日本相同种类最高,达到了64.71%,其次是与朝鲜、欧洲、俄罗斯-西伯利亚相同种类较多,分别为33.44%、30.96%、27.55%.区系成分组成主要以中国-喜马拉雅区系(东方区系)为主,欧洲-西伯利亚、中亚细亚区系成分为辅,亦有少量印度-马来西亚区系成分.更多还原
