As global forest areas decline and face increased risk from extreme events, optimizing types for long-term stability becomes crucial. However, empirical evidence the effects of mixing methods on carbon nitrogen dynamics in ecosystems remains limited. This study investigates five Southern China: Tsuga longibracteata W.C.Cheng pure forests, longibracteata–hardwood mixed longibracteata–Phyllostachys edulis (Carr.) J.Houz. longibracteata–Rhododendron simiarum Hance longibracteata–hardwood–Rhododendron forests (the tree species are all dominant community species). We examined one monoculture four categorized into tree–shrub by richness levels 1, 2, 3. measured (C) (N) content, along with C:N, coarse woody debris (CWD) at various decay stages adjacent topsoil (0–10 cm) to analyze decomposition rates their soil nutrients. Our results indicate that C content density CWD differed significantly among (p < 0.001). The exhibited highest N CWD, but lowest topsoil, alongside fastest rate. Soil C:N ratio showed highly significant differences 0.001), a difference 0.05). Optimal outcomes occurred level as excessive or insufficient can diminish rates. ecological benefits surpassed forests. Overall, these findings suggest do not always provide greater advantages than improper deplete soil.
