| 摘 要： | 研究了天童地区32种常绿阔叶树叶片的营养、结构特征，结果表明该地区常绿落叶植物叶种N含量的变化幅度为1.022%~2.744%，平均值是1.606%;P含量的变化幅度为0.032%~0.227%，平均值是0.086%，且N、P含量成显著相关；C含量变化幅度为36.49%~53.85%，平均值是45.00%;SLA 变化幅度为72.64~197.78，平均值是119.29;叶片的营养含量与C含量、SLA无关，而C含量与SLA成负相关；灌木的营养含量要低于乔木树种，灌木和中乔木的C含量要高于小乔木，但不同生活型植物SLA无明显差异。

| Abstract: | In the present paper, leaf nutrient and structural characteristics of 32 evergreen broadleaved plant species were studied. The results are as follows: leaf N varies from 1.022% to 2.744%, the average is 1.606%; leaf P varies from 0.032%~0.227% and the average is 0.086%;N and P are positively correlated; leaf C varies from 36.49% to 53.85%and the average is 45.00%;SLA varies from 72.64 to 197.78 and the average is 119.29;leaf C is negatively correlated with SLA, but nutrient content isn't correlated with leaf C or SLA of these three life forms isn't significant. |
