摘  要:【目的】阔叶红松林是我国长白山林区顶级植物群落,林内动物、植物种类丰富,分析阔叶红松林及阔叶混交林中腐木甲虫物种组成、多样性,以及林分因子对腐木甲虫的影响,有助于揭示腐木甲虫与森林生境变化的相互关系作用机制,为评价天然林在保持腐木甲虫多样性的作用,以及不同生境对腐木甲虫多样性的影响提供依据。【方法】2012—2013年,每年5月中旬—8月下旬的腐木甲虫活跃期,在吉林蛟河阔叶红松林、杨桦林、水胡林中利用飞翔拦截诱捕器持续采集林内腐木甲虫,通过甲虫的生物学、相关文献资料和数据库确定腐木甲虫种类。【结果】共采集到甲虫39个科239种,其中,腐木甲虫203种,7465个个体;叩甲科、露尾甲科、隐翅虫科和天牛科的数量和种类较多;四星蜡斑甲和条脊甲在本地首次被采集到。阔叶红松林2个林分中腐木甲虫具有较高的多样性,杨桦林和水胡林中多样性相对较低。不同林分对甲虫的物种数、个体数、丰富度指数和多样性指数均有显著影响。阔叶红松林2个林分中甲虫的物种数、个体数、丰富度指数都显著高于杨桦林和水胡林。郁闭度、平均胸径、每公顷蓄积、每公顷株数、灌木盖度对各类群影响不同,林分的郁闭度、平均胸径、公顷蓄积对大多数腐木甲虫有正向影响。【结论】阔叶红松林内腐木甲虫种类和数量比较丰富,林龄、胸径、蓄积高的阔叶红松林林分腐木甲虫具有较高的多样性,其在维持腐木甲虫多样性方面发挥着重要作用。天牛科的物种数、个体数在阔叶红松林林分中数量都高于杨桦林和水胡林。叩甲科是阔叶红松林中最大的类群,与其他类群不同,其在灌木盖度高和乔木株数多的杨桦林数量较多。【Objective】The mixed forest of Korean pine(Pinus koraiensis)with broad-leaved tree species is the climax forest community in Changbaishan Mountains of Northeast China.There are abundant animals and plants species.In this paper,the saproxylic beetles(Coleoptera)species composition,diversity and the effects of different forest stand factor on the beetles were analyzed in the Korean pine and broad-leaved trees mixed forests.This study aimed to reveal the interaction mechanism between habitat change of forest and saproxylic beetles,as well as to provide basis information for evaluating role of nature forest in protecting the diversity and effects of different habitats on diversity of saproxylic beetles.【Method】The saproxylic beetles specimens were collected by flying intercepted traps in Korean pine and broad-leaved trees mixed forests,poplar-birch forests,and ash-walnut forests during the whole active period of the beetles from middle May to late August of 2012 and 2013.The saproxylic beetles were identified by beetles biology,related literature and foreign saproxylic beetles database.【Result】Totally 239 beetle species in 39 families were collected,among which 203 species,and 7465 individuals belonged to saproxylic beetles.The number of the species and individuals of Elateridae,Staphylinidae,Nitidulidae,Cerambycidae were relatively richer.Helota gemmata and Rhysodes craciulus were collected for the first time in this area.The diversity of saproxylic beetles in two Korean pine and broad-leaved tree mixed forests was higher,while it was lower in poplar-birch forest and ash-walnut forest.The species number,individual number,richness index,diversity index of saproxylic beetles were significantly different in different stands,and they were higher in two Korean pine mixed with broad-leaved tree forests than in poplar-birch forest and ash-walnut forest.The canopy density,mean DBH,hectare stock,hectare stems,and shrub coverage had different effects on different saproxylic beetles groups.The canopy density,mean D
