    摘要:

    从生态序列的角度研究了左家自然保护区微地貌中大型土壤动物群落的分布格局,同时考虑到土壤因子对大型土壤动物的综合作用,从小尺度上探讨大型土壤动物群落与土壤因子的关系。研究结果表明,凋落物的种类和数量差异对大型土壤动物的分布影响明显,阴坡和阳坡的四个生境坡谷、坡麓、坡中、坡顶植被差异较小,土壤因子是研究区大型土壤动物序列分布的一个重要影响因子。微地貌条件下,土壤有机质、土壤含水率、pH、全氮、全磷变化趋势接近,土壤温度与土壤含水率、pH、土壤有机质、全氮和全磷这5个指标变化趋势相反,土壤有机质、土壤含水率、pH、全氮、全磷和土壤温度这6个指标对研究区主要的大型土壤动物类群的分布有重要的影响。

    Abstract:

    Spatial distribution of large-sized soil animal communities in a microtopographical range of the Zuojia Nature Reserve was studied from the perspective of ecological series,and relationship of large-sized soil animal communities with soil factors on a small scale was explored taking into account comprehensive effect of soil factors on soil fauna.Results show that in the circumstance that there was no big change in altitude above sea level,vegetation was notable in affect ing large-sized soil fauna. Difference in vegetation was limited between the four habitats,ridge,mesoslope,down-slope,and vale of the sunny slope and shady slope of the studied region,soil factors played an important role in distribution of the soil fauna along the slope in the research region.In a microtopographical range,the changes in soil organic matter,soil water content,pH,total N,and total P tended to be approximate,whereas the change in soil temperature was just the opposite.The effects of the six soil indices on distribution of dominating groups of large-sized soil animals were significant.
