Change in SOC storage from 2002 to 2008 in the Luoyugou catchment.

* Because the area of this catchment in 2008 was less than that in 2002, by 0.04 km2, so that about 71.58 t of SOC wasn't taken into the amount of SOC storage. Immature woodland refers to trees under 30 years of age since planting (SOCD = 24.22 Mg/ha), and mature woodland refers to trees more than 30 years of age since planting (SOCD = 30.44 Mg/ha).
