The role of disturbance and climate factors in determining the forest carbon balance was investigated at a Japanese cypress forest in central Japan with eddy flux measurements, tree-ring analyses, and a terrestrial biosphere model. The forest was established as a plantation after intermittent harvesting and replanting between 1959 and 1977, and acted as a strong carbon sink of approximately 500gCm−2year−1 for the measurement years between 2001 and 2007. A terrestrial biosphere model, BIOME-BGC, was validated using the eddy flux data at daily to interannual timescales, and the tree-ring width data at interannual to decadal timescales. According to the model simulation,…

 Highlights: ► We evaluated disturbance effects in the carbon balance of a Japanese plantation. ► The model was validated by using the eddy flux data and the tree-ring width data. ► Harvesting was more important in the long-term sink compared with climate or CO2. ► Long rotation length could be effective management activity to increase carbon sink.
