英文摘要	In this study, we selected karst areas of rocky desertification in southern China as a subject analyze the nutrient transport patterns of the plant-litter-soil continuum and the effect of soil environmental factors on plant stoichiometry in two areas: potential-mild and moderate-severe rocky desertification. The results show that (1) the carbon (C), nitrogen (N), and phosphorus (P) contents of plant leaves in karst areas are higher than those of litter or soil; (2) the plant leaves have a high C storage capacity, P sufficiency, and N deficiency; and (3) the Monte Carlo test of eight soil environmental factors showed that the influences of soil environmental factors on plant stoichiometry vary with the level of rocky desertification. In the area of potential-mild rocky desertification, soil pH, TP, C:P, and SOC were the main driving factors. In the area of moderate-severe rocky desertification, soil TP, TP, C:N, and SWC were the primary driving factors. The comprehensive analysis can provide a theoretical basis for nutrient transport and soil environmental factor regulation in areas with different levels of rocky desertification. It is necessary to target the primary factors for fertilization management and nutrient transport protection in future rock desertification control.
