摘要： 土壤动物群落空间异质性和空间格局，是揭示土壤动物生态学过程和形成机制以及生态系统服务功能的重要前提。本研究以凉水国家自然保护区为研究区域，于2015年7、8和10月采用陷阱法捕获阔叶红松林地表隐翅虫。基于地统计空间分析方法揭示地表隐翅虫群落的空间自相关性、空间异质性、空间分布格局及其与环境因子的关系。3次采样共捕获隐翅虫成虫421只22种，调查月份隐翅虫个体数和物种数均表现为强变异，群落组成具有显著差异。MoranI系数表明隐翅虫群落及物种个体数在0~300 m的空间尺度上表现为复杂的空间自相关性，并在某一尺度或尺度范围上具显著性。隐翅虫群落在调查月份内具有中等的空间异质性，其空间变异由结构性和随机性因素共同调控。随着季节变冷，群落空间格局单一，斑块结构不显著。物种之间的空间关系因物种的多度等级而不同，物种与环境因子之间存在复杂的(正的或负的)空间关联性，但简单Mantel检验并未发现二者存在显著的空间关联性；CCA分析结果表明，地形和土壤因子对地表隐翅虫物种分布变化的影响不显著。本文揭示了隐翅虫成虫空间异质性和空间格局的变化特征，为研究地表隐翅虫群落物种构建机制及生物多样性维持机制奠定基础。

Abstract: Understanding the spatial heterogeneity and spatial pattern of soil animal community is an important premise to reveal the ecological processes and formation mechanisms of soil animal community and related ecosystem services. The trap method was used to capture ground-dwelling Staphylinidae in a broadleaved and Korean pine forest in Liangshui National Nature Reserve in July, August, and October 2015. Based on the geostatistical analysis, we analyzed the spatial autocorrelation, spatial heterogeneity, spatial distribution pattern and its relationship with environmental factors of ground-dwelling Staphylinidae community. In total, 421 individuals that belonged to 22 species of Staphylinidae were caught in the three samplings. The species and individual abundance of Staphylinidae varied greatly among survey months. The community composition significantly differed among different months. Results of Moran’s I coefficient indicated that the species and individual abundance of Staphylinidae community showed a complex spatial autocorrelation in the 0-300 m spatial scale, being significant at some specific scales. Staphylinidae community exhibited a medium spatial heterogeneity, with spatial variability being regulated by both structural and random factors. The spatial pattern of community was simple. The patch structure of community was insignificant in the cold season. The spatial relationships among different species were various, and there was a complex (positive or negative) spatial correlation between species and environmental factors. However, the simple Mantel test demonstrated that there was no significant spatial correlation between the two. Results of CCA analysis showed that topographic and soil factors had no significant effects on changes of species distribution of ground dwelling Staphylinidae. Our results revealed the variation of spatial heterogeneity and spatial pattern of Staphylinidae, providing basis for understanding the mechanism underlying community assemblage and biodiversity maintenance of ground-dwelling Staphylinidae community.
