摘要
以上海市徐汇区为例,探讨了在农田、废弃地和绿地三种不同土地利用类型下土壤动物的分布特点.调查期间共获得大、中、小型土壤动物2006个,共25个类群.在农田中,弹尾类、螨类是优势类群;在废弃地中,双翅类幼虫、螨类、弹尾类和线虫类属于优势类群;绿地中,线蚓类、弹尾类为优势类群.线蚓类、螨类和弹尾类在农田、废弃地和绿地中同时出现的概率要大于其他类群,表现为弹尾类>螨类>线蚓类.在群落结构方面,废弃地中的优势度指数在几个月份中一直低于其他两种类型;绿地优势度指数比较高,均匀性指数和多样性指数不高;而农田10,11月的优势度指数高于绿地.
The relation between land use forms and soil animals in cities has not yet been deeply probed in China. Takinig Xuhui District of Shanghai as a case, the authors inquired into the distribution of soil animals in three different land types, namely farmland, deserted field and green space. The number of soil animal smaples got during the research perild reached 2006 species, 25 genera. Dominant genera in farmland are collembola and Acarina; in deserted field are Diplura (L), Acarina Collembola and Nematoda; while in green space are Enchytraeidate and Collembola.
The probability of simultaneous appearance of Enchytraeidae, Acarina and collembola is higher than that of other soil animals, showing collembola >Acarina>Enchytraeidae.
In terms of community structure, the dominance index on deserted field is the lowest in several months. On green space, the dominance index is relatively higher, whereas hte diversity index and evenness index are lower. On farmland , the dominance index in October and November is higher than that on green space.
