- Abstract:
-
The difference of soil organic carbon and total nitrogen contents for cropland, abandoned land, Robinia pseudoacacia and Pinus tabulaeformis woodlands in hilly loess region were analyzed to explore the effects of land use types on the storage of soil organic carbon (SOC) and total nitrogen (TN ). The results showed that:(1) the contents of SOC and TN decreased with the increase of soil depth, the surface soils had higher contents of SOC and TN than the subsoils, especially for abandoned land. The highly significant correlation between SOC and TN centents was found in each land use type; (2) in the surface soil layer (0—48 cm), the SOC content in Pinus tabulaeformis stand is significant higher than others, and the TN content of Robinia pseudoacacia stand is significant higher than others, there are not significant different among them in superficial layer(48—96 cm) and deep layer(96—160 cm); (3) the results also show that at the regional scale, abandoned land, Robinia pseudoacacia and Pinus tabulaeformis stands have remarkable SOC and TN sequestration compared with cropland, and the artificial forest is the best. The increase of forestland area will enhance the storage of SOC and TN in this region.
