【目的】探讨亚热带森林恢复过程中枯落物层和土壤层的C,N,P含量及其化学计量比的变化规律,为阐明亚热带次生林恢复对土壤养分的影响及森林恢复提供科学依据。【方法】采用空间代替时间的方法,以湘中丘陵区杉木人工纯林、马尾松+ 石栎针阔混交林、南酸枣落叶阔叶林和石栎+ 青冈常绿阔叶林作为1个恢复系列,分别在其1 hm~2的长期定位观测样地内,沿着坡面选择6块10 m × 10 m小样地,每块小样地随机设置2个1.0 m × 1.0 m样方,采集地表未分解层、半分解层、已分解层枯落物和0 ~ 10,1 0 ~ 20和20 ~ 30 cm土层土壤样品,测定C,N,P含量并计算C,N,P的化学计量比。【结果】随着森林恢复和阔叶树比例增大,同...

Objective: The objective was to investigate the stoichiometry of carbon (C), nitrogen (N) and phosphorus (P) in litter and soil in four forest types at different succession stages in subtropical region of China, in order to provide a scientific basis for understanding the mechanism of influence of restoration of subtropical secondary forest on soil nutrients and forest restoration. Method: The study was conducted in a permanent observation plot in size of 1 hm2at Dashanchong Forest Park in Changsha County, Hunan Province, China. The method of spatial sequence was used instead of time successio...
