【摘要】：在长白山地丘陵区选择次生落叶阔叶林、灌木林、采伐迹地以及耕地四种土地利用方式,对其土壤动物群落的组成、多样性和分布特征进行研究。结果表明:不同土地利用方式土壤动物群落的水平分布呈现明显的差异。采伐迹地中型土壤动物个体密度和耕地中型土壤动物类群数季节变化明显。次生落叶阔叶林和灌木林土壤动物分布随土层加深急剧减少,采伐迹地和耕地垂直分布递减和缓。同一季节土壤动物的丰富度指数和多样性指数在不同土地利用方式差异显著。土壤动物的多样性表现为灌木林最高,耕地最低。不同土地利用方式影响土壤动物群落的生态分布,其中pH、土壤有机质、有效磷和速效氮是影响长白山地丘陵区不同土地利用方式土壤动物群落分布的主导因子。
[Abstract]:In the hilly area of Changbai Mountain, four land use patterns, namely secondary deciduous broad-leaved forest, shrub forest, cutting land and cultivated land, were selected to study the composition, diversity and distribution of soil animal communities.The results showed that the horizontal distribution of soil fauna communities in different land use patterns was obviously different.The individual density of medium soil animals and the number of middle soil fauna groups of cultivated land varied obviously in season.The distribution of soil fauna in secondary deciduous broad-leaved forest and shrub forest decreased sharply with the deepening of soil layer, and the vertical distribution of cutting land and cultivated land decreased slowly.The richness index and diversity index of soil animals in the same season were significantly different in different land use patterns.The diversity of soil animals was the highest in shrub forest and the lowest in cultivated land.The ecological distribution of soil animal communities was affected by different land use patterns. Among them, pH, soil organic matter, available phosphorus and available nitrogen were the main factors affecting the distribution of soil animal communities in different land use patterns in Changbai Mountain.
