Abstract:The intensive management Moso bamboo plantation soil aggregates and its carbon storage were analyzed.The results showed that soil granule structure of Moso bamboo plantation was dominated by >5 mm aggregate for all the three soil layers,accounting for 26.39%~42.38% of all soil aggregate.Soil aggregates of 1~5 mm and <0.25 mm accounted for 14%~18% and 2.31%~6.73%,respectively.Mean weight diameter of soil aggregate in Moso bamboo plantation was 0.90 mm,which tended to increase with descending soil layers.The accumulation of soil organic carbon was significantly related to organic carbon in 0.25~3.15 mm aggregate.However,the correlations between soil organic carbon accumulation and organic carbon in both >3.15 mm and <0.25 mm aggregates were not significant.Moso bamboo plantation soil aggregate ratio of organic carbon in> 5 mm and 3.15 ~ 5 mm aggregate in 0~20 cm were 14.86% and 11.26%,lower than its 20~40 cm and 40~60 cm layer.That is to say the > 5 mm soil diameter aggregate organic carbon content decreased maybe the main reasons of long-term intensive management Mao bamboo plantation soil organic carbon content decreased.
