Background

Soil arthropods are key components in a soil ecosystem, are connection links between soil and vegetation, and participate in key ecological processes such as litter decomposition, nutrient circulation, harmful substance degradation and the like. Naturally-developing soil in which soil arthropods are mainly distributed between litters and soil and between roots and soil interfaces, they migrate, reproduce and feed between litters and soil by using soil porosity or digging nests and the like.

The surface soil of an ecological restoration area such as a coal mine is damaged, surface soil (0-30cm) and vegetation are restored through foreign soil backfilling and the like in the artificial restoration process, the deep layer is usually tailings or soil matrix, and the development of the soil is not hierarchical. The coal mine restoration area has unobvious soil layers and loose structure, and massive residues such as stones form a plurality of pores in the soil, and the pores provide unique microbial habitats for the migration and inhabitation of soil arthropods, so that the distribution rule of the soil arthropods can be changed. Therefore, the research on the type composition and quantity change rule of the soil arthropods at different depths in the ecological restoration areas such as coal mines and the like has important significance for accurately evaluating the diversity and ecological function change of the soil arthropods in the ecological restoration process of the mining areas. In addition, the research on the vertical change rule of the soil arthropod community and the key community can further deepen the understanding on the understanding of the soil arthropod action and the improvement of soil versatility in the ecological restoration process of the mining area.
