图2. 土壤和植物CO2碳稳定同位素比值(δ13C)通量协同观测系统(A)及冠层和生态系统CO2 δ13C通量观测系统(B)示意图。A中植物呼吸箱仅以叶片和土壤呼吸箱为例展示气路图(茎干和根呼吸箱气路图与叶片相同)。
Fig. 2. Diagram on cooperative observation system of the CO2 carbon stable isotope composition (δ13C) flux of soil and plant (A) and observation system of the CO2 δ13C flux of canopy and ecosystem (B). In A, we only take leaf and soil chambers as an example to show the flow diagram of gas system (stem and root chambers same as leaf chamber).
