在黑龙江省帽儿山国家生态站内，在20 m的固定样地内基于规则格网调查法，采用陷阱法逐日采集2015年8月30日至11月21日的地表甲虫，以揭示气温变冷季节地表甲虫小尺度空间的逐日动态变化规律。结果表明：调查中共捕获地表甲虫1 332只，隶属于5科、27个物种。在气温逐渐降低的季节，帽儿山红松人工林小尺度的物种组成以步行虫科、隐翅虫科、埋葬甲科和象甲科物种为主。随着气温的降低，地表甲虫的群落物种多样性和群落丰富度整体表现为逐渐降低的趋势，但存在日间波动性；Pearson相关分析表明，这种逐日动态趋势和温度有显著的相关性；这种逐日变化表现出物种之间的差异，步行虫科和埋葬甲科物种较多的活动于相对温暖的9月，而隐翅虫科物种则在相对较冷的10月出现峰值。

A regular grid survey was performed in a 20-m permanent plot in the Maoer Mountain Ecosystem Research Station in Heilongjiang Province, Northeast China. To reveal the daily dynamics of the above-ground beetles during lowering temperature season, we daily collected beetles using traps from August 30 th to November 21 th in 2015. The 1 332 individuals were captured, belonging to 5 families and 27 species. Carabidae, Staphylinidae, Silphidae and Curculionidae are dominant families in numbers for above-ground beetle communities on small scale during lowering season in aPinuskoraiensisplanted forest. Species and abundance of the communities were reducing with the decreasing temperature. However, a daily dynamics in richness and abundance of community was detected. From Pearson coefficient analysis, the daily dynamics were related to the temperatures of study area. Moreover, the daily dynamics was species dependence. Species of Carabidae and Silphidae were more activity in relatively warmer season, that is September. The number of Staphylinidae showed peak in relatively cooler season, that is October.

生物多样性的时空格局一直是生物地理学和群落生态学的重要研究内容，生物多样性的时空格局具有尺度依赖性[1]，即在不同的尺度条件下这种时空格局表现不同。目前的研究较多集中于地上生态系统和较大尺度生物多样性的时空格局，少有研究关注小尺度空间时空格局，对地下生物多样性小尺度时空格局的研究更是少见。……
