Background and AimsThe distribution patterns of soil carbon (C), nitrogen (N), and phosphorus (P) affect soil nutrients and plant growth, which is highly important for the conservation and restoration of soil ecosystems. Therefore, in this study, the stoichiometry of soil organic C (SOC), total N (TN), and total P (TP) in the Amygdalus pedunculata community and their relationships with influencing factors were analyzed.MethodsFive main distribution areas of A. pedunculata were selected in the XilinGol League. The plant community characteristics in these areas were investigated and soil samples were collected at depth intervals of 0-10, 10-20, and 20-30 cm. The SOC, TN, and TP concentrations were measured, and climatic data and soil texture data were collected. The key factors influencing the SOC, TN, and TP stoichiometry were investigated.ResultsFrom the topsoil layer to the deeper soil layer, the SOC, TN and TP concentrations decreased from 5.59 gkg-1 to 3.38 gkg-1, from 0.56 gkg-1 to 0.40 gkg-1, and from 0.12 gkg-1 to 0.11 gkg-1, respectively. The average stoichiometric ratios of SOC, TN, and TP were 8.96, 41.64, and 4.98, respectively. The changes in soil stoichiometry at different sites were influenced by complex interactions among climatic conditions, vegetation patterns, and soil properties.ConclusionLatitude, silt content, herbaceous plant and community diversity indices, and coverage significantly affected the stoichiometry of SOC, TN, and TP in the A. pedunculata community in the XilinGol League.
