In this study, two stands and natural grassland were selected in Taihe Red soil degraded area of Jiangxi Province to research the distributions and turnover characteristics of organic carbon in soil aggregates. The results showed that the proportion of macroagrregates was the largest and that of microaggregates was the lowest.The content of organic carbon of all aggregates was higher in the Schima plantation than that of the grassland. The organic carbon in soil silt (< 53 μm) was the highest. The δ¹³C value of soil aggregate in the surface soil had the highest decrease in grassland compared with the original soil, and moderate in broad-leaved forest. The turnover time of soil organic carbonin surface layer in coniferous forest was 41~53 years,lower than that in 10-20 cm soil layer. The turnover time of organic carbon in the clay particle of the two plantation was the shortest and that in the macroaggregate was the longest.The results also showed that vegetation restoration from evergreen broad-leaved Schima superba in the red soil region could effectively enhance soil fertility thus not only increasing the organic carbon content in the original soil, but also increasing the organic carbon content in the aggregate. However, the vegetation restoration effect of Pinu smassoniana plantationwas weaker than that of broad-leaved forest. So some measures should be taken to promote the restoration of coniferous forest.
