摘　　要：揭示群落物种空间格局与过程是土壤动物群落生态学研究的重点内容之一.本实验于2017年7月在黑龙江省凉水自然保护区采用陷阱法调查地表鞘翅目土壤动物,基于地统计分析方法研究20 m×20 m空间尺度地表鞘翅目土壤动物对于食物资源利用的分布格局特征.结果表明:所有调查共捕获地表鞘翅目成虫246只,经鉴定分为7科25种,其中葬甲科(Silphidae)、步甲科(Carabidae)和隐翅虫科(Staphylinidae)为群落的优势科.葬甲科空间分布格局主要受食物资源的调控表现为明显的中心聚集现象,绝大多数个体聚集在样地中心食物资源附近.葬甲科分布格局与鞘翅目群落的格局类似,食物资源主要对葬甲科具有调控作用,且葬甲科个体数在鞘翅目群落中占有较大比例,因而鞘翅目群落空间格局与葬甲科空间格局具有一致性,葬甲科一定程度上决定了鞘翅目群落的格局特征.One of the most important tasks in soil animals community ecology is identifying the spatial patterns of the community and identifying the underlying processes that control such patterns.On July 2017,Coleoptera soil animals were collected using pitfall traps from Liangshui natural reserve of Heilongjiang Province. A study was conducted to investigate impact of food resources on ground –dwelling Coleoptera community patterns in 20 m × 20 m spatial scalebased on geostatistics analysis method. The results showed that 246 Coleoptera adults were captured in total which belongs to 7 familys and 25 species, Silphidae, Carabidae and Staphylinidae were dominant families of Coleoptera community. Spatial distribution pattern of mass families mainly influenced by food resources showed obvious central aggregation phenomenon,that most individuals gathered near food resources at center of sampling sites. Spatial pattern of Coleoptera adults is similar to Coleoptera community pattern,and food resources mainly regulate Silphidae individuals which has occupy large proportion in Coleoptera community. Therefore spatial pattern of Coleoptera communities was consistent with spatial pattern of Silphidae families and the Silphidaehad determined the pattern characteristics of Coleoptera communities.
