摘要: 2011年4月下旬在江苏省盐城市5种城市绿地(杨树林、公园绿地、苗圃、草坪和油菜地)对春季大型土壤动物群落结构以及功能群进行了分析。结果表明:不同绿地中的类群数、丰度均存在显著差异;功能群类群数、丰度大小趋势为植食性>腐食性>肉食性;大型土壤动物群落表现出明显的表聚现象;绿地类型、土壤层及其交互作用对大型土壤动物类群数、丰度均存在显著作用;除草坪与油菜地、苗圃与公园绿地2组对比中的植食性与非植食性丰度数据频数分布无显著差异外,其他绿地间有显著差异;系统聚类及非度量多维排序分析结果显示,草坪和油菜地间群落较相似,其他群落间差异较大。

Abstract: In the last ten-day of April 2011, an investigation was conducted on the soil macrofauna in five different urban green spaces (poplar plantation, park green space, nursery, lawn, and rapeseed field) in Yancheng City of Jiangsu Province, aimed to understand the community structure and functional groups of soil macrofauna in the City in spring. There existed significant differences in the macrofauna group number and abundance among different green spaces. The number and abundance of the functional groups followed as phytophage > saprozoic > camivorous. An obvious surface assembly phenomenon of soil macrofauna was observed. Green space type,soil layer, and their interaction had significant effects on the group number and abundance of soil macrofauna. Among the green spaces except lawn vs. rapeseed field and nursery vs. park green space, there were significant differences in the abundance frequency distribution of phytophage and non-phytophage. Hierarchical clustering and non-metric two-dimensional scaling ordination showed that the soil macrofauna communities were similar between lawn and rapeseed field, but differed between other green spaces.
