“…Our study's finding of a strong linear relationship between daily GPP and APAR at all sites differs from previous works Rayment and Jarvis, 1999;Oechel et al, 2000;Saigusa et al, 2002;Turner et al, 2003). For example, Turner et al (2003) found that the relationship was nonlinear in forest ecosystems because of the saturation of photosynthesis with increasing photosynthetic photon flux density (PPFD).…”

“…This shift of dominant functional types could promote the high production. The GPP was higher than that of deciduous forest site located in similar latitude (Saigusa et al 2002) and closer to that of tropical rain forest (Malhi et al 1998). Thus, humid temperate grassland in Tsukuba has high potential of CO2 uptake due to managing by mowing once a year.…”

CO2 exchange was measured using eddy covariance technique during 2001, 2002, and 2003 in a humid temperate C3/C4 co-occurring grassland in Japan. The interannual variability in cloudiness of Asian monsoon will be an important forcing in CO2 exchange. Early summer and autumn is a period with continuous rainy and cloudy days peculiar to the Asian monsoon region. , and contributed to negative net ecosystem CO2 exchange. The annual variations of gross primary production and net ecosystem exchange were sensitive to that of photosynthetic photon flux density.

Abstract:The physiological principles predicting growth (3-PG) model is generally used to estimate gross primary productivity (GPP) in forest plantations. All existing parameter values in the 3-PG model for GPP estimation have been set as the standard values for eucalyptus and pine plantations. We propose that the 3-PG model can be applied to deciduous broadleaf forests dominated by Betula platyphylla via appropriate parameterization of their structure and functions. The allometric relationships between stem biomass and stem diameter, and between foliage biomass and stem biomass, were determined for the biomass partitioning ratio. Additionally, a temperature modifier was considered appropriate because it affected canopy quantum efficiency. After parameterization, the model showed a good correlation between the estimated results and the data from experimental plots in central and northern Japan. At both sites, GPP peaked around August and was 0 during the winter, when the canopy is bare of leaves. Furthermore, a sensitivity analysis was conducted to determine the most influential parameter relative to the output. GPP was sensitive to changes in canopy quantum efficiency and optimum temperature. Among the meteorological data used, solar radiation and temperature had great impacts on GPP, therefore, these parameters should be carefully considered to produce accurate results.
