Abstract
This is a protocol to evaluate gross primary productivity (GPP) of a forest stand based on the measurements of tree's sap flow (SF), C derived water use efficiency (WUE), and meteorological (met) data. GPP was calculated from WUE and stomatal conductance (g), the later obtained from SF up-scaled from sampled trees to stand level on a daily time-scale and met data. WUE is obtained from C measurements in dated tree-ring wood and/or foliage samples. This protocol is based on the recently published study of Klein , 2016 .
摘要
这是一个基于树木液流（SF）、碳衍生水分利用效率（WUE）和气象（met）数据测量来评估林分总初级生产力（GPP）的方案。GPP由WUE和气孔导度（g）计算得出，后者通过将采样树木的SF按日时间尺度向上扩展到林分水平并结合met数据获得。WUE通过对 dated 树轮木材和/或树叶样本中的碳进行测量得到。本方案基于Klein 2016年最近发表的研究。
