红壤侵蚀区不同植被恢复模式土壤有机碳含量、密度及储量分布特征
Distribution characteristics of soil organic carbon in different vegetation restoration patterns in red soil erosion areas
[目的]为了明确红壤侵蚀区不同植被恢复模式土壤有机碳的分布特征。[方法]以经过 27年植被恢复与重建后的 6种林分为研究对象,以未加人工干扰的自然恢复地为对照,设置 20×20 m的标准样地,采集 0～10 cm、10～20 cm、20～30 cm和 30～40 cm土层的土壤样品,测定其有机碳含量、土壤容重等理化性质,探究红壤侵蚀区土壤有机碳含量及有机碳密度的分布特征。[结果](1)对比自然恢复地,6种人工植被恢复模式的SOC含量均显著增加(p…查看全部>>
[Objective]To clarify the distribution characteristics of soil organic carbon in different vegetation restoration modes in the red soil erosion area.[Method]Taking six types of forest stands after 27 years of artificial vegetation restoration and reconstruction as the research objects,and natural restoration sites without artificial disturbance were used as controls.20×20 m standard sample plots were set up,and soil samples were collected from 0～10 cm,10～20 …查看全部>>
