以湘中丘陵区檵木—南烛—杜鹃灌草丛(LVR)、檵木—杉木—白栎灌木林(LCQ)、马尾松—柯(又名石栎)—檵木针阔混交林(PLL)、柯—红淡比—青冈常绿阔叶林(LAG)4种林地为对象,采用Tiessen和Moir修正后的Hedley磷(P)分级方法,研究不同植被恢复阶段林地土壤P各分级组分含量及其组成比例。结果表明:随着植被恢复,同一土层全磷(TP)、总无机磷(Pi)、总有机磷(Po)含量增加,NaHCO_3-Pi、NaOH-Pi、HCl-Pi和 NaHCO_3-Po、NaOH-Po属于快速积累型,Residual-P属于缓慢积累型,Resin-Pi属于稳定型;不同植被恢复阶段林地土壤Pi以NaOH-Pi为主,Po以NaOH-Po为主,土壤P以Residual-P和Po为主;随着植被恢复,同一土层Po含...

Four different vegetation communities,which represented the primary forest successional sequence in the central hilly area of Hunan Province,China,were chosen in this study.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).The modified phosphorus fractionation method of Tiessen and Moir,which was put forward...
