Accumulation of vegetation biomass is a crucial process for carbon fixation in the early stage afforestation and primary driving force subsequent ecological functions. Accurately assessing storage allocation elements plantations essential their management estimating sink capacity. However, current knowledge patterns within plant organs at community level limited. To clarify distribution level, we measured five typical loess hilly-gully region. We assessed main drivers element accumulation by employing redundancy analysis random forest. Results revealed significant differences storages among effect plantation type on organs. Furthermore, dominant factors influencing C–N–P were found to be inconsistent. While was mainly influenced stand openness, total soil nitrogen, diversity, openness water content. Overall, spatial structure had an important influence both allocation, but conditions played more role than storage. Random forest results showed that often differed. The regulation elemental could regulated major growth demand resources, while other limiting class factors, which differed from those organ reflect adaptation strategies resources ecosystems combination with plants. Our study provides valuable insights enhancing C estimates serves as reference regulating local scale.
