2003年7月和9月对吉林省中、西部平原区天然次生林、农田、居民点园地、防护林和天然割草场等典型生境进行了土壤弹尾虫的调查,用Tullgren法提取弹尾虫,应用个体密度、类群数量、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,了解土地利用差异对土壤弹尾虫群落结构的影响。共捕获土壤弹尾虫2亚目8科12属5 531头,优势类群为Onychiurus、Folsomia、Acanthocyrtus、XenyllaColoburella属, 占总捕获个体数的90.3%。弹尾虫类群空间分布的广狭与个体数量的多寡在吉林省中、西部平原区呈现出明显的一致性;中部平原区与西部平原区土壤弹尾虫群落组成差异主要体现在优势类群个体密度方面;生境类型明显影响弹尾虫个体密度分布,其中农田、居民点园地和防护林土壤弹尾虫个体密度较低,在不同土层间分布比较均匀,但生境差异对弹尾虫类群数的影响不明显;同时农业生产活动也降低了弹尾虫群落多样性。

The soil collembolas in the middle and west plains of Jilin province were investigated with the emphasis on such indices as individual density,number of groups,and community diversity,richness and evenness in relation to the types of land use, i.e., farm garden, farmland, Three-North Forest Shelterbelt, natural secondary forest and natural mowing pasture. The soil collembolas were extracted with Tullgren extractor and identified to the genus level with the aid of microscope. A total of 5 531 soil collembola individuals were captured, which fell into 2 sub-orders, 8 families, and 12 genera. Onychiurus, Folsomia, Acanthocyrtus, Xenylla and Coloburella were the dominant groups that accounted for 90.3% of the total individuals. A considerable difference in the number of individuals existed between the natural forest and other habitats affected by human activity. The collembolas were distributed evenly in different layers of soil profile in all habitats affected directly by humans for both samples collected in July and September, especially in July. In these habitats affected intensively by farming activity during the summer, more collembolas appeared in soil of the lower stratum. While the strong effects on the group richness were not observed in all habitats. These results suggested that the types of land use affected the species richness and abundance, and human activity had a significant impact on the soil collembola community. 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. The agricultural activity reduced the collembola diversity. The difference of the collembolan community composition between the middle plain and the west plain of Jilin province was shown mainly by their difference in the dominant group density in all habitats.
