| 摘 要： | 在河北北部的森林-草原交错区，对人工林和次生林的土壤节肢动物群落结构的时空变化进行了调查。结果表明：蜱螨目和弹尾目在所调查的样地中为常年的优势类群；土壤节肢动物类群数随夏秋春季节的变化逐渐减少，个体数秋季最多，春季最少，夏季次之；大型和中小型土壤节肢动物类群数和个体数在不同林地中的变化规律不同。不同地带次生林中的土壤节肢动物数量大于人工林，而且多样性也高于人工林；交错区不同生态环境土壤节肢动物的类群数和个体数的垂直分布都随着土层深度的增加呈递减趋势，且表聚性非常明显。但有的样地土壤节肢动物的个别层次有逆层的现象

| Abstract: | In this study, time and space variation of structure of soil arthropod community in artificial and secondary forests in the ecotone of forest-steppe at northern part of Hebei province, were investigated thoroughly. The results showed that Arcarina and Collembola were the dominant groups. The groups of soil arthropod varied with seasons, being the maximum in summer, fewer in autumn, and the minimum in spring. But the individuals of soil arthropod were the maximum in autumn and the minimum in summer. The group and individual numbers of macro and meso fauna had different rules in different plots. The research showed that the numbers of groups and individuals in secondary forest were greater, and the diversity was higher than artificial forest. The group and individual numbers of soil arthropod were reduced in the three different areas, and they showed obviously natural of surface gathering, but in some plots there were the contrary rule. |
