    摘要:

    中亚热带低山丘陵区,气候温暖、湿润,植被生长繁茂,土壤动物资源丰富。通过对湘中丘陵山地红壤森林土壤动物群落定位调查,共获得36018只土壤动物标本,计有31类,其中蜱螨类、弹尾类和线虫类为优势类群,三类群占动物总量的92.33%,为森林土壤动物群落的主体。其他28类常见类群和稀有类群,分别占土壤动物总量的5.28%和2.39%。土壤动物密度(104indm-3)受多种环境因素制约,其主要限制因素是植被类型和土壤干湿季节变化,根据4个采样点的定位调查结果,以地带性常绿阔叶次生林和灌草丛群落最丰富,分别为78.41(104indm-3)和75.33(104indm-3),人工针叶林土壤动物密度仅为56.41(104indm-3)。土壤动物在土体中垂直分布与土壤有机物质的表聚和土壤理化特性的垂直差异有密切关系,在森林土壤中主要分布于凋落物层和土壤的腐殖质层,向下锐减。

    Abstract:

    The midsubtropical low mountain and hilly region in middle Hunan is warm and humid in climate,covered with flourishing vegetation that has an abundant resource of soil animals in the soils underneath.A total of 36 018 animal samples were gathered from sampling sites during soil animal investigation in the hilly mountains of Middle-Hunan Province.They could be sorted into 31 groups,with Acarina,Collembola and Nematoda,being the dominant groups,which occupied 9233% of the total samples,and formed the main body of the forest soil animal community.The others were common groups and rare groups,accounting for 5.28% and 2.39%,separately.Soil animal intensity (10 4 ind m -3) was affected by a number of factors,and vegetation and drywet alternation of soil are the main limiting factors.The findings at 4 sample sites showed the zonal evergreen broad-leaved forest and bushes-weeds were the highest in average density of soil animal,reaching up to 78.41 (10 4 ind m -3) and 75.33 (10 4 ind m -3),respectively,and the artificial coniferous forest the lowest,being only 56.41 (10 4 ind m -3).The vertical distribution of soil animals in the soil was closely related with the surface accumulation of organic matter and the vertical variation of soil physiochemical characteristics.The results show the soil animals are mainly distributed in litter and humus layers,showing an obvious phenomenon of surface accumulation,and a downward decreasing trend.
