Other Abstract

It is not clear how plantation affect the soil organic carbon (SOC) in deep soil for
terrestrial ecosystem. Based on space for time method, we studied the effect of Pinus
tabulaeformis plantations at three developmental stages (young forest, middle age forest and
mature forest) on the soil organic carbon (SOC) and soil readily oxidizable carbon (ROC) in 0-
200 cm soil profile. The results showed that SOC content and storage significantly increased in
soils with different developmental stages of Pinus tabulaeformis plantation compared with
abandoned cropland in 0-200 cm profile. In the 0-100 cm soil layer, average SOC content of
mature forest, middle age forest and young forest were 2.03, 1.85 and 1.59 times more than that
in abandoned cropland, respectively. SOC storage in shallow and deep soil layers contributed
61.0%-69.8% and 30.2%-39.0% to total SOC storage in the whole profile (0-200 cm) at all of
the investigated developmental stages. SOC storage in shallow soil layer varied significantly
among different developmental stages, however, no obvious difference of SOC storage in deep
soil layer was observed at all developmental stages. Compared to that in abandoned cropland,
the ROC storage in soils of young forest, middle age forest and mature forest increased 54.8%,
82.0% and 91.6% in shallow soil layer and 32.4% , 40.9% and 58.1% in deep soil layer,
respectively. ROC storage in deep soil layer contributed 31.2%-33.3% to total ROC storage in
the whole profile (0-200 cm) at all developmental stages. SOC and ROC content in shallow
soil layer were influenced by a number of factors, furthermore, ROC content in deep soil
showed significant correlations with the plant height, root biomass, litter thickness and litter
biomass. In conclusion, construction of artificial forest may significantly improve the soil
carbon pool in both shallow and deep soil profiles.
