Insert Table 3
The response of SOC and TN storage to LUCCs varied greatly among sampling depths (Table 3). Generally, the deforestation decreased the SOC and TN storage within the 0-100 cm profiles, with the SOC loss ranging from -0.69 to -0.36 from shallow to deep sampling. The SOC loss efficiencys in the 0-20 and 0-30 cm layers were much higher than those in deeper soil layers, with a loss of 49.8% and 53.7% respectively. The effect magnitude of SOC loss gradually decreased with the sampling depth.
