马尾松叶片-凋落物-土壤的碳氮磷化学计量特征
|
摘要
以赣南马尾松天然林为研究对象,采用空间代替时间的方法,通过典型样地调查和样品测定,分析不同林龄马尾松林叶片、凋落物和土壤的C、N、P含量及化学计量特征。结果表明:(1)各龄组的C、N、P含量均表现为土壤<凋落物<叶片,且三者之间均呈现显著性差异(P<0.05),叶片C、N、P含量均在近熟林达最大值;土壤C含量为成熟林最大,而N、P含量则近熟林最大;凋落物的C含量则成熟林最小,N、P含量为近熟林最小。(2)不同龄组之间,C含量在叶片、凋落物、土壤中均有显著差异(P<0.05),N、P含量及C∶N、N∶P在土壤中有显著差异(P<0.05),C∶N和C∶P在凋落物中有显著差异(P<0.05)。(3) C、N、P含量及其化学计量比在叶片、凋落物、土壤各自的相关性优于两两之间,而两两间的相关性主要体现在叶片P与凋落物N、叶片P与土壤P、叶片N∶P与凋落物N∶P。土壤有机质的矿化作用偏慢,林木的生长、凋落物分解均受到N元素的限制,P元素的有效性偏低;叶片、凋落物、土壤的主要化学计量指标之间具有明显的耦合性,P元素相比C、N元素在叶片、凋落物、土壤三者之间的相关性更为明显。
Using datum of typical plots survey and space instead time method,investigated natural Pinus massoniana forest to analyze the content of C,N,P and stoichiometric characteristics of leaf,litter and soil in different age forest. The results showed that:(1) the content of C,N and P in each age group were all shown as soil
