常绿阔叶林藤本植物叶片N、P、K生态化学计量学特征
【目的】研究广西大明山国家级自然保护区常绿阔叶林中30种藤本植物叶片N、P、K生态化学计量学特征，为丰富群落生态化学计量学提供基础数据。【方法】在大明山天坪站保存完好的常绿阔叶林中设置20m×20m标准样地80块，共3．2ha，在每个标准样地左下角设置5rex5m的小样方，对藤本植物多样性进行调查，根据重要值，采集30种藤本植物叶片，进行叶片N、P、K含量测定。【结果】叶片N、P、K变化范围分别为3．52-54．71、0．21-3．36、0．48-4．23g／kg。各个化学计量因子之间存在一定的线性关系，草质藤本叶片N：K含量均大于木质藤本，P含量差异不显著。【结论】大明山常绿阔叶林中多数藤本...

[MethodJEighty blocks of 20 m × 20 m standard sample with the total area of 3.2 ha in Tianping station well-pre- served evergreen broad-leaved forest were chosen, and then a 5 m × 5 m plot from every standard sample left bottom was set to observe the diversity of liana. Leaves of 30 lianas were collected for determining the content of N, P, K in the lab based on the important value. [Result] The results showed that contents of N, P and K in leaves were 3.52-54.71 g/kg, 0.21-3.36 g/kg and 0.48- 4.23 g/kg, respectively. The stoichiometri |
