摘要
2010年5月,对暖温带地区山西农业大学庭院四种绿地类型进行了土壤弹尾纲动物的调查,用干漏斗法(Tullgren)提取鉴定到属,应用个体密度、群落多样性、丰富度和均匀度等指数,研究土壤弹尾虫群落结构特征,了解不同绿地类型的差异对土壤弹尾虫群落结构的影响。共获得弹尾虫个体1724只,分属3目4科8属,其中,Entomo-bryidae(长跳科)为优势科包括3属,而Hypogastruridae(球角跳科)个体数却占绝对优势。不同绿地类型对弹尾纲的种群组成有显著影响,多样性指数H′特征为:样地Ⅰ>样地Ⅱ>样地Ⅲ>样地Ⅳ,I号和Ⅱ号样地弹尾纲群落分布均匀且优势类群明显,其多样性指数高,群落发育较好。
Collembola communities living in the four yard greenbelts of warm temperate zone were investigated in the campus of Shanxi Agricultural University in May 2010.All the Collembola types were extracted with Tullgren extractor and identified to the genus level with the aid of microscope.The characteristics of Collembola community structures in different habitats were analyzed by using different indices,i.e.Shannon-wiener index,Marglef index and Pielou index.A total of 1724 Collembolas were collected in four greenbelts which belonged to 3 orders,4 families and 8 genera.Among them,Entomobryidae was the dominant groups of the soil Collembolas communities in these four greenbelts including 3 genera.Hypogastruridae was the dominant groups in number.The composition of Collembola was affected by different types of greenbelts.The diversity index（H′） of Collembola showing：plot Ⅰplot Ⅱplot Ⅲplot Ⅳ.Equal distribution and obvious dominant groups in the plot Ⅰ and plot Ⅱ leaded to high diversity index,gave the fact that the Collembola groups develop better in the two plots than others.
