摘　　要：为明确不同采样方式对分析昆虫群落结构特征的影响,以苍山东坡中山湿性常绿阔叶林为研究地点,采用马氏网(MS)、地陷阱法(XJ)、灯诱法(DY)以及扫网法(SW)4种采样方式,进行为期1年的昆虫群落调查,比较不同采样方式及组合采集的昆虫群落结构特征,分析结果的差异性,明确不同采样方式的优劣及可替代性。结果显示:在采集的59科13340头昆虫中MS捕获41科6896头,XJ捕获31科6201头,DY捕获24科141头,SW捕获22科102头;比较不同采样方式采集到的各目数、科数、物种数和个体数,MS最佳,XJ和DY次之,SW最差;不同采样方式的优势类群存在差异;4种采样方式的群落相似性相互间差异较大(Cs≤0.60);除SW+XJ、DY+XJ及SW+XJ+DY组合外,其余的组合采样效果相当,可以酌情替换。To determine the effects of different sampling methods on the structural characteristics of insect communities,the wet evergreen broad-leaved forest on the eastern of Cangshan mountain was taken as the study site,and four sampling methods,which are the Malaise trap method(MS),the ground trap method(XJ),the light trap method(DY),and the net method(SW),were used to conduct the survey of insect communities for one year,and compare the structural characteristics of insect communities obtained by the different sampling methods,analyze the differences in results,and clarify the advantages,disadvantages,and substitutability of different sampling methods.The results showed that among the 59 families and 13340 insects collected,41 families and 6896 heads were captured by MS,6201 specimens belonging to 31 families were captured by XJ,141 specimens belonging to 24 families were captured by DY and 102 specimens belonging to 22 families were captured by SW.Comparing the number of families,species,and individuals collected by different sampling methods,the MS is the best,followed by the XJ and DY,and the WB is the worst.There are differences in the advantageous groups of different sampling methods.There are significant differences in community similarity among the four methods(Cs≤0.60).Except for the combinations of SW+XJ,DY+XJ and SW+XJ+DY,other combinations have similar sampling effects and can be replaced.
