Farmland ecosystem is the most active part of the human activities. In recent years, The research about soil fauna in the farmland ecosystem was widely attention. Soil Collembola, one of the dominant species, could well reflect the influence of human activities on the environment. Diversity of soil Collembola was changed with the change of ecological environment. Based on the research of soil collembolan in the farmland ecosystem, it could be better evaluate the quality of the farmland ecosystem.
To investigate the diversity of soil Collembola from farmland ecosystems in the Changbai Mountains, three typical geomorphic types, including basalt platform, granite low-mountain, and granite hills, were chosen from the Changbai Mountains. The study was conducted in spring (May), summer (July), and autumn (September) of 2015. The results showed that the diversity characteristics of different landforms was varied. Species: number of soil collembola is highest in granite low mountain during spring. In summer, soil collembola obtained highest in basalt platform, while in autumn, soil collembola was highest in granite hill.
Regardless of landform, soil Collembola had the highest diversity during autumn. The Shannon-Wiener indexes were significantly different in the three landforms during summer (P < 0.05), and the one-way ANOVA showed that a significantly lower abundance and richness of soil Collembola was evident in the basalt platform compared to that of the other landforms in autumn (P < 0.05). In this study, geomorphic types and seasonal variations had significant effects on diversity of soil Collembola.
