摘　　要：为了解松花江三湖国家级自然保护区不同林型中食腐甲虫群落结构及多样性特征,通过悬挂高、低拦截式挡板诱捕器对食腐甲虫进行连续采集,利用单因素方差分析判断不同林型甲虫群落结构及α多样性指数差异,利用皮尔森相关系数及冗余分析判断不同α多样性指数间相关性及对林分因子倾向性,利用非度量多维尺度分析、置换多元方差分析、相似性百分比及杰卡德系数判断不同林型间甲虫β多样性。结果表明:共采集到食腐甲虫昆虫6027头,隶属于47科208属311种。其中,单属单种的科为15种,3种林型食腐甲虫共有科为31种,共有物种为64种。对比同一林型中不同食性及不同林型中同一食性甲虫个体数与物种数时,仅有粪食性甲虫个体数在不同林型间无显著差异。不同林型优势科差异显著,其中,鳃金龟科个体数与物种数差异极显著,叩甲科个体数与物种数差异显著,埋葬甲科个体数差异显著,物种数差异极显著;同一林型不同优势科个体数与物种数差异均为极显著。不同林型优势种个体数差异明显,其中,褐绒绢金龟、阔胫玛绢金龟和棕籽绒绢金龟差异极显著,黑斑锥胸叩甲差异显著,Dalopius puerilis无显著差异;同一林型不同优势种个体数差异均为极显著。α多样性在不同林型具体表现为个体数、物种数、香农指数、辛普森指数与皮洛指数差异极显著,玛格列夫指数、Chao1指数与ACE指数差异显著;其中,玛格列夫指数、Chao1指数、ACE指数与郁闭度和平均胸径呈较强正相关性,物种数与枯落物厚度呈极强正相关性,个体数与植被盖度呈较强正相关性,香农指数、辛普森指数与皮洛指数与植被盖度呈负相关性。β多样性显示,不同林型间群落结构差异显著,且褐绒绢金龟、棕籽绒绢金龟和阔胫码绢金龟对群落差异贡献较大,各林型间相似性均互为中等不相似。To understand the community structure and diversity characteristics of saprophagous beetles in different forest types in the Sanhu National Nature Reserve along the Songhua River,saprophagous beetles were continuously collected using suspended high and low interception traps.One-way analysis of variance was employed to assess differences in beetle community structure andα-diversity indices among different forest types.Pearson correlation coefficients and redundancy analysis were utilized to evaluate the correlation between differentα-diversity indices and propensity to forest stand factors.Non-metric multidimensional scaling,permutation multivariate analysis of variance,similarity percentages,and Jaccard coefficients were used to assessβ-diversity of beetles among different forest types.The results showed a total collection of 6027 saprophagous beetle specimens belonging to 311 species,208 genera,and 47 families.Among them,15 families were represented by a single genus and species,while 31 families were shared by saprophagous beetles across all three forest types,with 64 species being common.Comparison of individual and species numbers of the different coprophagous beetle in the same forest type and the same coprophagous beetle in different forest types showed that only the number of individuals of coprophagous beetles did not differ significantly in different forest types.Significant differences were observed in dominant families among different forest types,with notable differences in the number of individuals and species within the Melolonthidae family,significant differences in the number of individuals and species within the Elateridae family,significant differences in the number of individuals within the Silphidae family,and extremely significant differences in the number of species within the same family.The differences in number of individuals and species of different dominant families in the same forest type were all highly significant.The number of individuals of same dominant species varied signific
