为揭示植被恢复对土壤有机碳(SOC)库的影响机制,采用空间代替时间的方法,以湘中丘陵区地域相邻、环境条件基本一致的檵木(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(又名石栎)(Lithocarpus glaber)-檵木针阔混交林(PLL)和柯-红淡比(Cleyera japonica)-青冈(Cyclobalanopsis glauca)常绿阔叶林(LAG)作为一个恢复演替序列,设置固定样地,采集0–10、10–20、20–30、30–40 cm土层土壤样品,测定不同恢复阶段SOC含量(C_(SOC))和SOC密度(D_(SOC)),...

Aims: Vegetation restoration plays an important role in the accumulation and storage of soil organic carbon (SOC). Our objectives were to investigate the effects of vegetation restoration on SOC and to explain the underlying mechanisms of carbon sequestration during vegetation restoration in the mid-subtropical China. Methods According to the disturbance intensity and the degree of restoration, we used the space-for-time substitution method by selecting four different types of vegetation communities, composed of Loropetalum chinense-Vaccinium b...
