Recent studies have indicated that tree carbon accumulation in subtropical forests has been negatively affected by global change phenomena such as warming and drought. However, the long-term effect of nitrogen addition on plant storage remains poorly understood these regions. In this study, we conducted a 10-year field experiment examining experimental N growth Chinese fir forest. The levels were 0 (control), 60, 120, 240 kg ha-1 yr-1, effects divided into stand individual levels. results at scale was not By contrast, significant impacts different size classes sequestration found under treatments, which amount significantly enhanced with class. Our findings highlight importance community structure characteristics forests, but additional regulates
