摘　　要：通过巴氏罐诱集法对黄帝陵4个不同类型侧柏林地及1个对照样地进行了地表昆虫多样性研究,从5个样地共采集到地表昆虫1816头,隶属7目29科,以鞘翅目(占59.65%)和膜翅目(占26.1%)昆虫数量最多,其中步甲科(占33.75%)、蚁科(占25.98%)、金龟科(占14.88%)是优势类群。在科级水平上,物种数和Shannon-Wiener多样指数由高到低的顺序均依次为样地Ⅴ(梨园村古柏林)>样地Ⅰ(侧柏幼树林)>样地Ⅲ(侧柏中龄林)>样地Ⅱ(侧柏古树林)>样地Ⅳ(古柏-油松混交林)。样地间的植被覆盖率、坡向、人为管理措施等是影响该地域地表昆虫多样性的主要因素。Litter-layer insect communities in 4 different kinds of Platycladus orientalis forest in Huangdi Mausoleumand and one control sampling area were investigated by means of pitfall traps. 1816 specimens were collected in five sampling areas, which belonged to 7 orders and 29 families. In these specimens, Coleoptera （ accounting for 59.65% ） and Hymenoptera （ accounting for 26. 1% ） were the most abundant groups. Carabidae （ accounting for 33. 75% ） , Formicidae （ accounting for 25. 98% ） and Scarabaeidae （accounting for 14. 88% ） were dominant groups. On family level, the species richness and Shannon-Wiener index were the highest in sampling area V （ old cypress forest in Liyuan village）, followed by sampling area I （ young cypress forest） , sampling areaⅢ （ middle age cypress forest）, sampling area Ⅱ （ old cypress forest） and sampling area IV （mixed old cypress and Chinese-pine forest） . Insect diversity level is closely related to the factors such as vegetation coverage, slope aspect and management meatures, etc.
