城市新规划地土壤动物群落组成和多样性:以上海市世博会会址为例

作者采用野外调查和群落多样性指标数据统计结合的方法,对上海市世博会会址区域内土壤动物群落组成和多样性进行了研究,目的是了解该地区的土壤健康状况,并为城市规划提供科学依据。采样共获得土壤动物10,765头,隶属于23个类群。中小型土壤动物中蜱螨目是该地区的主要优势类群,弹尾纲是次优势类群;大型土壤动物中,后孔寡毛目为主要优势类群,等足目、鞘翅目和腹足纲为次优势类群。总体结果显示:该地区土壤动物种类丰富,其垂直分布整体遵循随土壤层的加深而递减的趋势;但水平分布因采样点的不同存在显著性差异。

Community composition and diversity of soil fauna in the land use of city planning: a case study in Shanghai World Exposition Site

In order to provide scientific evidence of soil health for city planning, the diversity and composition of the soil animal community of the site of World Exposition Shanghai China 2010 were investigated. A total of 10,765 soil animal individuals belonging to 23 groups of soil animals were collected, of which Acarina was the dominant group of soil meso- and micro-fauna, and Collembola was the secondary one. As for soil macrofauna, Oligochaeta was the dominant group, while Isopoda, Coleoptera, and Gastropoda were the secondary ones. The results indicated that soil animals were abundant at this site. The soil animals reduced along with the increasing soil depth, and their distribution varied significantly at different sampling sites.
