- Abstract
In order to understand the characteristics of soil fauna community structure in different altitudes of Picea schrenkiana in the Western Tianshan Mountains, the soil fauna under P. schrenkiana at different altitudes (1414 m, 1595 m, 1724 m, 1868 m) was selected as the research object. According to the altitude from low to high, they were taken as plot-Ⅰ, Ⅱ, Ⅲ, and Ⅳ. A total of 4003 soil fauna, belonging to 3 phyla, 7 classes, 21 orders and 41 kinds were collected. The average density of soil fauna in plot-Ⅳ was the highest, and the number of soil fauna groups was the highest in the plot-Ⅰ. The richness index of soil fauna was the highest in the plot-Ⅰ and the lowest in the plot-Ⅳ, and there was a significant difference between the plot-Ⅰ and the plot-Ⅳ (P<0.05). The density, number of groups and diversity of soil fauna are different under different altitude gradients. In short, the change of altitude gradient leads to a different ecological distribution of soil fauna. In addition, this study has shown that organic matter, total nitrogen, total phosphorus, total potassium and readily available P are the dominant factors affecting the diversity and distribution of soil fauna communities.
