中文摘要	【目的】调查宁夏罗山国家级自然保护区垂直植被带不同生境步甲昆虫群落组成和多样性,探讨该地区步甲分布和物种多样性与生境的关系,为该地区生物多样性的长期监测和保护提供依据。【方法】根据宁夏罗山国家级自然保护区的生境类型和海拔高度,设置亚高山草甸A(SMA)、亚高山草甸B(SMB)、针叶林A(CFA)、针叶林B (CFB)、针阔混交林(MBCF)、阔叶林缘(BLFE)、灌丛(DS)和荒漠半荒漠草地(DSDG)8个不同样地,于2015年5 8月利用巴氏罐诱法对8个不同样地的步甲科昆虫多样性进行调查。【结果】共采集到步甲昆虫3 749只,隶属于12属24种,种类组成体现了荒漠半荒漠区系特点。个体数量最多的是直角通缘步甲和弗氏步甲,分别占总数量的39.11%和20.42%,为该区域的优势类群。直角通缘步甲在沿海拔梯度的各生境均有分布,弗氏步甲仅在油松林生境无分布。不同植被带步甲种类组成和优势类群差异较大,其中亚高山草甸和灌丛生境步甲物种数最多,各有17种,亚高山草甸步甲个体数量也最多;针叶林生境步甲物种数最少,仅有6种,个体数量也最少。步甲活动的高峰期为7 8月。各物种在各生境内的季节变化趋势与不同生境植被生长季节相关。灌丛生境的步甲Shannon-Wiener多样性指数和丰富度均最高,优势度最低;针叶林生境均匀度最高,Shannon-Wiener多样性指数和丰富度较低。主成分分析显示,生境相近的样地步甲昆虫群落结构也相似,步甲群落分为三大类群,样地DS、BLFE和MBCF的步甲群落聚为一类,样地CFA和CFB的步甲昆虫群落聚为一类,样地SMA、SMB和DSDG的步甲群落聚为一类。【结论】垂直植被带生境差异性与步甲昆虫群落的物种多样性和相似性密切相关,维持生境异质性是保护步甲多样性的关键。
英文摘要	【Objective】 This study investigated community composition and diversity of carabid beetles in Luo Mountain National Nature Reserve in Ningxia and analyzed the relationship between the beetles diversity and habitat to provide basis for long-term monitoring and protection of biodiversity.【Method】 The community structure and species diversity of carabid beetles were conducted from May to August in 2015 using pitfall traps in the Luo Mountain. Carabid beetles were caught from six types and 8 sample plots of vegetation habitats along the elevation gradient including subalpine meadow (SMA plot and SMB plot) , coniferous forests (CFA plot and CFB plot),mixed broadleaf-conifer forest (MBCF plot) , broad-leaved forest edge (BLFE plot),deciduous shrub (DS plot) and desert semi-desert grasslands (DSDG plot).【Result】A total of 3 749 carabid beetles belonging to 24 species and 12 genera were collected. Pterostichus gebleri and Carabus vladimirskyi were the dominant species in the area,accounting for 39.11% and 20.42%,respectively. Pterostichus gebleri was caught in all habitat gradients,and Carabus vladimirskyi was not captured only in the CFB plot. The community composition and dominant species of carabid beetles were also significantly different among different habitats. The number of species and individuals of beetles in SMA plot and DS plot were more than in other vegetation habitats, while those in the CFB plot was the lowest. Beetles peak activities were in July and August and various species in vertical vegetation zones had different seasonal trends. Among the plots,carabid beetle community in DS plot had the highest Shannon-Wiener diversity and species richness, but the lowest dominance. Evenness in CFB plot was the highest while diversity and species richness in CFB plot were the lowest. Principal component analysis showed that carabid beetle communities were distinctly separated into three groups.【Conclusion】 The community composition and diversity of carabid beetles were closely related to the spatial heterogeneity. Keeping habitat heterogeneity is helpful to protect species diversity.
