Redundancy analysis (RDA) results and significance level among litter and soil properties. Red solid circles indicate an extremely significant positive correlation (P < 0.01); red semicircles indicate a significant positive correlation (P < 0.05); red hollow circles indicate a positive correlation (P > 0.05); blue solid circles indicate a strong, significant negative correlation (P < 0.01); blue semicircles indicate a significant negative correlation (P < 0.05); and blue hollow circles indicate a negative correlation (P > 0.05). Note: A–N represent the litter dry mass, organic carbon, nitrogen, phosphorus, lignin, cellulose, carbon/nitrogen, carbon/phosphorus, carbon/lignin, carbon/cellulose and lignin/cellulose, respectively; a-m represent the soil pH, conductivity, soil water content, bulk density, organic carbon, nitrogen, phosphorus, carbon/nitrogen, carbon/phosphorus and nitrogen/phosphorus, respectively.
