These findings indicate that wind-based litter redistribution among bare, S. There were significant differences in the removal rate among the different litter types.
#Be not blown about as a leaf on the wind Patch#
The rate of litter removal due to wind was highest for the almost bare surface type (P4) and lowest for the shrub patch (P1) and Stipa grandis community (P2) types. The results show that compared with almost bare ground patches, patches with vegetation cover had significantly higher litter accumulation, with the shrub patch type having the highest accumulation amount. Four vegetation patch types and six litter types were used to investigate the impacts of vegetation patches on litter mobility and accumulation. In this study, we aimed to test the following hypotheses: (1) vegetation patches can reduce litter removal and facilitate litter accumulation, (2) litter mobility results in the heterogeneous redistribution of carbon and nutrients over the land surface, and (3) litter removal rates differ among different litter types (e.g., leaf and stem).
Litter decomposition is an important source of soil organic matter and nutrients however, few studies have explored how vegetation patches affect wind-driven litter mobility and accumulation.
