Soil Fauna Community Diversity and Distribution Characteristics in Different Secondary Forest of Changbai Mountains
The soil fauna community diversity and distribution characteristics of the different secondary forest in Changbai Mountains were investigated in this paper.Soil fauna from three secondary forest habitats,including the Basalt platform,Granite low mountain and Granite hill in Changbai Mountain area,were studied in the spring (May),summer (July) and fall (September) of 2015.The soil fauna density and their group numbers differed among the habitats with seasonal fluctuations.The density variation of macro soil fauna with season was not significant,whereas that of meso-micro soil fauna was great.The density and groups of Granite low mountain secondary forest was the lowest,while the Basalt platform secondary forest was significant higher than other two habitats.The diversity indices of macro soil fauna in three habitats were showed the same dynamic trend.The change of soil fauna diversity had no significant differences with different season.The meso-micro soil fauna diversity index was showed a significant increase or decrease trend,which obviously different to macro soil fauna.The meso-micro diversity index of Basalt platform was significant higher than other two habits.Through the RDA analysis of soil fauna and environmental factors we found that the soil fauna responded highly to soil organic matter,total nitrogen,total phosphorus and available nutrient.Oribatida was the dominant group of the meso-micro fauna which distribution showed a significant positive response to soil temperature and humidity.The study can provide the soil zoological theoretical basis for the management and ecological restoration of secondary forest.
