【目的】探究不同植被恢复阶段林地凋落物层现存量及其碳(C)、氮(N)、磷(P)化学计量的差异,为亚热带地区退化林地的植被恢复和管理提供科学依据。【方法】采用空间代替时间的方法,在位于亚热带丘陵区的湖南省长沙县选取地域相邻、环境条件基本一致的4种处于不同植被恢复阶段林地: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)作为一个恢复序列,设置固定样地,按未分解层、半分解层和已分解层采集凋落物层分析样品,测定凋落物层现存量以及不同分解层凋落物C、N、P含量及其化学计量比。【结果】1)凋落物层及其各...

【Objective】In order to explore the difference of litter layer existing amount and its carbon(C),nitrogen(N),phosphorus(P)stoichiometry in different vegetation restoration stages,so as to provide scientific basis for vegetation restoration and management of degraded forest land in subtropical region.【Method】By using the space-for-time substitution method,we selected four different types of plant communities,comprising of Loropetalum chinense+Vaccinium bracteatum+Rhododendron simsii scrub-grass-land(LVR),Loropetalum chinense+Cunninghamia lanc...
