Global change may cause unparalleled supplies of soil nutrients and further lead to stoichiometric imbalance of nitrogen (N) and phosphorus (P) in terrestrial plants. While previous studies had reported the effects of global change factors on plant N, P contents and their ratios, few had examined whether or how these factors may influence the scaling of these two elements.

全球变化会改变植物氮到磷的比例吗？实证检验

全球变化可能导致土壤养分的大量供应，并进一步导致陆生植物中氮（N）和磷（P）的化学计量失衡。尽管先前的研究报告了全球变化因素对植物氮，磷含量及其比例的影响，但很少有人研究这些因素是否或如何影响这两个元素的规模。
