采用土壤颗粒分级方法,以湘中丘陵区地域相邻、环境条件基本一致的4种林地:檵木—南烛—满山红灌草丛(LVR)、檵木—杉木—白栎灌木林(LCQ)、马尾松—石栎—檵木针阔混交林(PLL)和石栎-红淡比-青冈常绿阔叶林(LAG)为对象,研究土壤有机碳(SOC)及不同粒径土壤颗粒有机碳含量随着林地退化的变化特征,剖析林地退化对中亚热带森林SOC库的影响机制。结果表明:随着林地退化,>2μm砂粉粒百分含量增高,而

Four different forest lands were chosen in the hill region of central Hunan,China.They were: Loropetalum chinense -Vaccinium bracteatum.-Rhododendron mariesii scrub-grass-land (LVR),L. chinense-Cunninghamia lanceolata-Quercus fabri shrubbery (LCQ),Pinus massoniana-Lithocarpus glaber-L.chinense coniferous-broad leaved mixed forest(PLL)and L.glaber-Cleyera japonica - Cyclobalanopsis glauca evergreen broad-leaved forest(LAG).In order to elucidate the effects of forest degradation on soil organic carbon,the soil partical-size fractionation method w...
