摘要
为探讨城市工业区凋落物中土壤动物的群落特征,作者于2005年夏季至2006年春季,对上海市宝山钢铁公司厂区不同功能区(生产区、过渡区和办公区)凋落物中的土壤动物进行了调查。共捕获土壤动物52,070只,分别隶属于3门10纲19目,优势类群为蜱螨目和弹尾目,二者共占总数的90.60%;常见类群为鳞翅目和近孔寡毛目。不同功能区的优势类群相同,常见类群相异,且土壤动物总密度随着生产区—过渡区—办公区呈现递减趋势;不同功能区凋落物和不同绿化类型(乔木和灌木)中的5种指数呈现规律不同:Simpson优势度指数(C)、Margalef丰富度指数(D)为中间过渡区高,两边区域低;Pielou均匀度指数(E)为生产区>办公区>过渡区;DG指数和Shannon-Wiener多样性指数表现为生产区>过渡区>办公区;凋落物中土壤动物数量的季节变化为冬季>秋季>夏季>春季,而类群数量为冬季=秋季>夏季=春季;不同功能区凋落物pH值、有机碳、总氮和总磷含量不同,其中pH值、总氮达到显著性差异,对凋落物中土壤动物有一定影响。
To find out the relationship between the abundance and diversity of soil animals and soil characteristics in industrial zones,we investigated soil animals in litters of different functional zones in Baoshan Steel Plant. A total of 52,070 soil animals were collected using Tullgren funnel,belonging to three phyla,10 classes and 19 orders. The dominant groups were Arcarina and Collembola,accounting for 90.60% of the total in terms of individual numbers. The common groups were Lepidoptera and Oligochaeta plesiopora. The results indicated that different functional zones had similar dominant groups but different common groups. Soil animal reduced along a gradient of production zone,transition zone,office zone. Similarity index showed that the five indices were different in different functional zones. The density-group index （DG） showed the following pattern： production zone 〉 transition zone 〉office zone. The seasonal change of the total number of soil animals were ranked as： winter〉autumn〉summer〉spring,while the number of soil animal groups were ranked as： winter=autumn〉summer=spring. The pH,TOC,TN and TP of litters in different functional zones were different,which might have impacts on the distribution of soil animals.
