对长白山区高速公路边坡的中小型土壤动物进行了调查,探讨了人工植被恢复后公路边坡土壤动物的群落特征.研究区内共捕获中小型土壤动物32类,4 807只.结果表明:不同生境土壤动物群落类群数和个体数量的多样性特征存在差异,阳坡土壤动物的类群数大于阴坡,而个体数量小于阴坡;土壤动物群落个体和类群主要集中分布在0～5cm土壤层,而且具有时间上的变化,均为7月<9月<次年5月.土壤动物与环境要素的相关分析表明,植被恢复后土壤动物类群与土壤pH和全P含量相关不明显,与土壤有机质、全N含量和土壤含水率呈显著的正相关,与全K含量呈显著负相关关系;个体数量与土壤中全N、全P、全K含量、土壤含水率和pH相关不明显,而与土壤有机质的含量呈显著的正相关.人工植被恢复的边坡生境还处在恢复阶段,条件较差,可以用甲螨的个体数量粗略地评价植被恢复的发展阶段.A/C比值特征不仅仅具有纬度地带性,而且具有经度地带性,同时受人为活动的干扰. A survey was conducted on the small and medium sized soil fauna on the highway slope in Changbai Mountain Area to investigate the community characteristics of soil fauna on highway slopes after artificial vegetation restoration.The total 32 small and medium soil fauna were found in the study area and the number was 4 807. The results showed that: There were differences in the diversity characteristics of soil fauna community numbers and individuals in different habitats. The number of soil fauna in sunny slope was larger than that in shady slope, while the number of individuals was smaller than that in shady slope. Individuals and taxa of soil fauna were mainly concentrated in 0 ~ 5cm soil layer , But also changed with time from July
