Abstract: Taking the low, medium and high altitude samples of Lushan as the research object, this paper explored the characteristics of soil animal communities and soil humus characteristics at different altitudes, and provided scientific basis and data for the study and environmental management of soil animals in Lushan. In late September 2019, three sample sites were set up at low, medium and high altitudes in Lushan to investigate and experiment with soil animals and humus components. A total of 1 210 soil animals were acquired in a variety of lands, belonging to 12 families,20 orders,5 classes and 2 phyla. The number of individual stoes and DG indices of soil animals increased with altitude and then decreased, while the number of groups increased with the increase of altitude. The differenceof between the various underground humus components was significant （P<0.05）, the humus, huminic acid, huminin and humin increased and then decreased with the elevation increased, the rich acid was on the rise, and the change trend of PQ ratio and HA/FA and humus was consistent.
