Carbon (C) and phosphorus (P) in soil are closely related to plantation types afforestation practices. However, the trade-off between C P response different restoration patterns on degraded hilly land is still not clear. In this study, four patterns, including natural recovered shrubland (NS), Castanopsis hystrix (CH), 10-species mixed (10MX), 30-species (30MX) were selected, physicochemical properties readily oxidized carbon (ROC) layers of 1 m depth measured understand effects artificial pool their southern China. The results indicate that total (TP) content each layer was observed follow order CH > 10MX 30MX NS, with monoculture (CH) exhibiting higher levels TP than plantation. storage NS (59.61 t hm−2) (57.71 similar, while boasted highest (64.99 being lowest (42.75 hm−2). deep (20–100 cm), presented for both index (CPI) management (CMI). Moreover, structural equation model (SEM) revealed CMI directly regulated by soil-available N, activity influenced pH. Thus, our study suggests compared plantations, demonstrates lower uptake utilization, resulting a content. Furthermore, showed superior fixation capacity over those plantations. These contents commonly among patterns. Therefore, tree composition nutrient regulation necessary maintaining balance keeping sustainability lands.
