of individuals, and the remaining 18 species were rare populations, accounting for only 5. 07% of the total number of
individuals. The 12⁃year⁃old poplar plantation had significantly more beetle species and total individuals than other stand
communities in different aged poplar plantations and provide scientific support for exploring the structure, function and
productivity maintenance for poplar plantations ecosystems.【 Method】 Poplar plantations of different stand ages ( i.e., 6,
ages, while the 18⁃year⁃old poplar forest had the lowest. The species diversity of soil beetles varied by 33.83% across all
plantation ages. Diversity increased first and then decreased with age of poplar plantation, with maximum and minimum

稀有种群,仅占总个体数的 5 07%;地表甲虫种类数和个体数量随林龄的变化,表现为 12 年生杨树人工林显著
高于其他林龄,18 年生林分最低;地表甲虫物种多样性随杨树人工林林龄增加呈先增后减的变化规律,最大值
与最小值分别出现在 12 年生和 18 年生杨树人工林,变幅为 33.83%,其中 6、9、15 年生杨树人工林地表甲虫多样
( Harpalus calceatus) 、 毛 婪 步 甲 ( Harpalus griseus ) 、 条 斑 叶 象 ( Hypera conmaculata ) 、 黄 斑 青 步 甲 ( Chlaenius
micans) 、红角婪步甲( Harpalus amplicollis) 和脊青步甲( Chlaenius costiger) ,占总个体数的 15.82%;其余 18 种均为
析杨树( Populus spp.) 人工林地表甲虫群落组成、结构及多样性特征。 【 结果】 研究期间共采集到地表甲虫标本
1 460 只,分属于 7 科 28 种。 其中优势种为蠋步甲( Dolichus halensis) 、亮足细胫步甲( Agonum gracilipes) 、铜绿婪
步甲( Harpalus chalcentus) 和巨短胸步甲( Amara gigantea) ,其数量占总个体数的 79. 11%;常见种为谷婪步甲
性无显著差异。 总之,地表甲虫个体数量、物种多样性变化,从杨树幼龄林至中龄林阶段表现为增加趋势,在中
龄林到成过熟林阶段表现为减少趋势。 【 结论】 地表甲虫个体数量、物种多样性与杨树人工林生长发育阶段密
切相关,处于快速生长发育阶段的中龄林具有较高的物种多样性,处于成熟林阶段的杨树人工林地表甲虫的个
体数量和多样性均显著降低。
