为探讨秦岭松栎混交林优势灌木叶片N、P化学计量特征，以松栎混交林优势灌木叶片为研究对象，通过野外采样和室内分析，对优势灌木叶片N、P化学计量特征进行了研究。结果表明：秦岭山地松栎混交林林内优势灌木为白檀、木姜子和胡枝子；白檀和木姜子、胡枝子叶片N的质量分数间存在显著差异，但3种灌木叶片中P质量分数和（质量分数ω（N）∶ω（P））无显著差异；优势灌木叶片N与P质量分数间、P质量分数与ω（N ）∶ω（P）间呈正相关关系；优势灌木叶片N质量分数与土壤N质量分数、叶片P质量分数与土壤P质量分数间呈正相关关系。

We studied the N and P stoichiometric characteristics in dominant shrubs in a Pine-oak mixed forest in the Qinling Mountains.By field sampling and lab analysis, we determined the contents of N and P in leaves of dominant shrubs and soil.The dominant shrub species were Sympol cos paniculata , List ea cubebaand Lespede za bicolro .There were significant differences in N contents among three kinds of shrub leaves.However, there were no differences between the contents of P and N∶P in leaves.There were positive correlations between the contents of N and P in leaves of dominant shrub species, as well as between P and N∶P. There were positive correlations between N contents in shrub leaf and soil, as well as P contents in shrubs leaf and soil.
