摘要：

Organic-C concentrations were highest in the surface horizons and declined with depth, but relatively high concentrations of organic P were found in the subsoils studied. The depth of this organic P-accumulation zone varied in patterns indicative of climatic and topographic controls on the leaching process. Both the total contents and vertical distributions of organic C and P, therefore, suggest that stoichiometric relationships between C and P should not be assumed, as both climate and topography may influence soil C and P levels to different extents and through different processes. -from Authors
