Based on plot data of shoot utilizing (Ⅰ), shoot and timber utilizing (Ⅱ) and timber utilizing (Ⅲ) stands of Phyllostachy edulis located at the hilly region in central Hu'nan Province, a research was carried out on the vertical distribution and seasonal dynamics of soil readily oxidizable carbon (ROC) and its relationship with soil total organic carbon (SOC), soil temperature, soil humidity and soil nutrients under the three types of management pattern. The results showed that the average ROC concentrations of type I, II and III were 2.77-5.15 g·kg-1, 2.55-3.67 g·kg-1 and 3.21-5.36 g·kg-1, and the ROC storages were 17.19-32.52 t·hm-2, 17.29-24.60 t·hm-2 and 19.04-31.85 t·hm-2 respectively. The vertical distribution showed that the ROC concentrations and storages decreased with the increase of soil depth in the three stands. Moreover, the soil layer of 0-20 cm was the main distribution layer of SOC. For seasonal dynamics, the ROC concentrations and storages in April were obvious lower than that in other season
