Abstract—

This article presents the measurement results of CO₂ and heat fluxes using the eddy covariance system between an old-age spruce forest and the atmosphere. It further examines daily and seasonal courses of CO₂ net exchange, ecosystem respiration, and gross photosynthesis. A close relationship has been established between the average daily CO₂ net exchange and net radiation over the course of a year. The efficiency of water use relative to organic matter production in the spruce forest has been calculated.

俄罗斯东北欧洲云杉林与大气之间的二氧化碳，热量和水蒸气通量

摘要—

本文介绍了使用云杉林和大气之间的涡度协方差系统对CO ₂和热通量的测量结果。它进一步检查了CO ₂净交换，生态系统呼吸和总体光合作用的每日和季节性过程。在一年当中，平均每日CO ₂净交换量与净辐射量之间建立了密切的关系。已经计算了云杉林中相对于有机质生产的水利用效率。
