Litter distribution significantly affects nutrient cycling, energy transfer, and various ecosystem services. However, little is known about how microtopography litter accumulation on the forest floor. Distribution characteristics of stocks at slope-scale their relationship with topography rock exposure rate (RER) in a typical subtropical karst China were determined by measuring stock RER 300 1 × m grids 10 120 square limestone hill. The results showed that (1) average was 691.54 ± 332.60 g∙m-2, among which 65.81% undecomposed litter; (2) spatial uneven moderate variation, presenting five aggregated areas four sparse entire slope; (3) there significant negative correlation between (R = −0.37, P < 0.01), increased increasing slope gradient position; (4) coupled directly affected via redistribution process indirectly decomposition altering microenvironment, reshaped pattern stocks. Our research highlights importance complex morphology ecosystems cycling transfer mediating redistribution, providing new insights into formation high environmental heterogeneity habitats.
