为阐明中亚热带植被恢复对土壤有机碳(SOC)稳定性的影响机制,采用空间代替时间方法,在湘东丘陵区选取檵木(Loropetalum chinense)-南烛(Vaccinium bracteatum)-杜鹃(Rhododendron simsii)灌草丛(LVR)、檵木-杉木(Cunninghamia lanceolata)-白栎(Quercus fabri)灌木林(LCQ)、马尾松(Pinus massoniana)-柯(Lithocarpus glaber)-檵木针阔混交林(PLL)、柯-红淡比(Cleyera japonica)-青冈(Cyclobalanopsis glauca)常绿阔叶林(LAG)作为一个恢复系列,采用室内恒温培养(碱液吸收法)测定SOC矿化速率及其累积矿化量(C_m),结合主成分和逐步回归方法分析C_m、SOC矿化率与植被因子和土壤因子的关系。结果表明...

Aims Soil organic carbon (SOC) mineralization and its controlling factors are critical for understanding the mechanisms that regulate C storage and loss processes. Our objectives were to accurately assess the impacts of vegetation restoration on SOC mineralization and to illustrate the underlying mechanism of changes in SOC stability with vegetation restoration in the mid-subtropical region of China. Methods Four types of vegetation communities (Loropetalum chinense-Vaccinium bracteatum-Rhododendron mariesii scrub-grass-land (LVR), Loropetalum ...
