中文摘要：

对海南师范大学热带城市庭院绿地土壤动物群落进行了调查,共获得土壤动物103只,隶属3门9纲19目.其中蜱螨目、线蚓目为优势类群,膜翅目、弹尾目、综合目、鞘翅目、等翅目、蜘蛛目、大蜈蚣目、倍足目、双翅目、原尾目、双尾目和地蜈蚣目为常见类群,其余为稀有类群.研究结果表明,作为微域环境的海南师范大学城市庭院绿地土壤动物群落存在2个明显的生态地理特征：1）与热带地域生态系统相似,种类比较丰富,优势类群却不很明显;2）与热带地域自然生态系统相比,其类群与数量明显偏少.经初步分析认为,这种微域环境下的土壤动物群落生态地理特征与人为干扰因素有关.

英文摘要：

Soil animals＇ communities living in the yard greenbehs of tropical city were investigated in the campus of the Hainan normal university, a total of 103 soll animals were collected in five greenbelts which belonged to 19 classes, 9 orders and 3 phylums. Among them, Acarina and Enchytraeida were the dominant groups of the soil animals communities in these five greenbehs. Hymenoptera, Symphyla, Coleoptera, Isoptera, Araneae, Diplopoda, CoUembola, Diptera, Protura, Diplura and Ghilopoda were the frequent population. The others were rare type groups. The results showed that, as a microcosms environment, soil fanua in yard greenbelt of Hainan Normal University have two distinct eco-geographical characteristics： First, they are similar with the tropical ecosystems, namely it has more rich species but no obvious predominant groups. Second, compared to tropical natural ecosystem, their groups and numbers are evident on the low side. After a preliminary analysis, we consider that ecogeographical characteristics of soil fauna is relevant to human disturbance,
