摘要: 为了解城市草坪不同管理方式下土壤动物的群落结构,于2015年7月,大型动物采用手捡法,中小型土壤动物采用干、湿漏斗法进行分离,对未除草、人工除草和人为践踏3种管理方式下草坪土壤动物的群落结构进行调查。试验共捕获土壤动物1 009只,隶属于2门11纲20科;3种草坪管理方式下土壤动物平均密度排序为未除草(3.84×104只·m-2)>人工除草(3.63×104只·m-2)>人为践踏(2.79×104只·m-2),土壤动物类群数为未除草(33)>人工除草(27)>人为践踏(20)。未除草与人工除草管理方式的土壤动物密度-类群指数(DG)有显著性差异(P<0.05),各管理方式间土壤动物群落多样性指数(H')差异不显著(P>0.05),大型土壤动物类群数差异性显著(P<0.05)。表明城市草坪土壤动物的丰富度、多样性和均匀度与人为干扰强度呈紧密的负相关关系。

Abstract: To reveal the community structure of soil fauna in different managements in urban lawn, no weeding, weeding and trampled grassland were chosen as sample plots in July 2015. Soil macro-fauna were picked up by hands. nematodes and meso-fauna were separated and collected from the soil samples by Baermann and Tullgren methods, respectively. Results showed that soil fauna had 1 009 individuals, belonging to 2 phylums, 11 classes, 20 families. The order of the average density of soil fauna was no weeding (3.84×104 ind.·)>weeding (3.63×104 ind.·)>trampling (2.79×104 ind.·). The order of species number was no weeding (33)>weeding (27)>trampling (20). There were significant differences between no weeding and weeding on the density-group index (DG) (P<0.05). The various diversity index (H') among the lawn managements were not significantly different (P>0.05), while the specie numbers of soil macro-fauna were significantly different (P<0.05). Results indicated that the richness, diversity and homogeneity of soil fauna were closely negatively correlated with intensity of human interference.
