摘要
为了研究植物叶片的功能,选取北京百花山上主要乔木、灌木和草本植物共30种,分别测定其叶片鲜重(Wf)、干重(Wd)、叶干物质含量(LDMC)、面积(A)、比叶面积(SLA)等5项叶片性状因子。结果表明,SLA与LDMC和Wd都呈负相关;A与Wf和Wd分别呈显著正相关。这些关系分别存在于乔、灌、草三种生长型及所有植物中。
The main objective is to study the correlation among the leaf traits of plants in the Baihua Mountain, Beijing. Nearly 30 species of tree, shrub and herb were sampled from the field of Baihua Mountain. And the leaf traits of fresh weight （FW,wf）, dry weight （DW,wd） , area （AR,A）, leaf dry matter content （LDMC） and specific leaf area （SLA） were measured. The results showed that there are significant negative correlation between SLA and LDMC, SLA and DW; and positive correlation between AR and FW, AR and DW. All these relations are found in all the species and tree, shrub, herb respectively.
