“…The biomass expansion factor for trees younger than 20 years was 1.57; the biomass expansion factor for trees older than 20 years was 1.23; the ratio of below ground biomass to above ground biomass was 0.25; the wood density (tonnes/m 3 ) was 0.314; and the carbon content t-C/t-dm was 0.5 (Environmental Ministry 2009;Fukuda et al 2003). By multiplying 3.67(44/12=molecule of CO 2 /molecule of C) by the amount of the carbon stock present, the amount of CO 2 can be calculated.…”

“…Planted forests in the present study was conducted are highly productive of timber, especially from the main tree species (Cryptomeria japonica). Because this species is very broadly distributed (Fukuda et al 2003), the simulations described here, which are based on real data, could also be applied to planted forests in other regions. In other words, Cryptomeria japonica, which is the target tree species in this study, is the most common tree species in Japanese planted forests (Forestry agency, 2007), so the work is applicable to other parts of Japan.…”

“…Note that the litterfall for broad-leaved trees accounted for only 2 and 5 of the total for the UP and the LP, respectively. We assumed that the C content of the dried biomass was 50 , similar to a previous study on Japanese cypress forests Fukuda et al, 2003 . The plant area index PAI; the one-sided plant area per unit ground area, m 2 m -2 was measured during August 2012 at the nine R soil measurement points in each plot using digital nonspherical color photographs Nikon COOLPIX990 .…”

Differences in aboveground biomass along a slope position are often overserved because of varying levels of nutrient availability. Such differences can affect the spatial variation in soil respiration Rsoil via changes in biological factors e.g., fine root biomass and litter mass , in addition to environmental factors. This study clarified the differences in Rsoil and the factors affecting Rsoil, between the upper and lower slope positions with contrasting aboveground biomass, within a small watershed covered by a Japanese cypress forest.The soil water content SWC was lower, whereas the soil temperature Tsoil and fine root biomass were higher in the upper plot UP than in the lower plot LP . Rsoil was negatively correlated with SWC, but positively correlated with Tsoil and fine root biomass. These results gave rise to a positive effect of Rsoil on the UP. However, Rsoil was comparable between the plots. The results from a multiple linear regression model indicated that factors other than SWC, Tsoil, and fine root biomass increased Rsoil in the LP. We speculate that high litterfall could enhance Rsoil in the LP, as litterfall is an important source of decomposed respiration. The higher aboveground net primary production and lower fine root biomass in the LP suggest that more carbon was allocated aboveground and less carbon was allocated belowground, resulting in comparable Rsoil but different contribution of aboveground and belowground sources on Rsoil between the plots. It is considered that differences in phosphorus availability between the plots caused the different carbon allocation patterns, even at a small spatial scale of less than 100 m.

Abstract:The objective of this study is to modify the process-based stand growth model for Cryptomeria japonica in the photosynthetic production process so as to more reasonably represent the stand growth pattern after thinning. We introduce five leaf strata to the canopy structure, and then parameterize the light-curve for each leaf stratum by Bayesian calibration via the Markov Chain Monte Carlo (MCMC) method. We examine the behavior of the model using the estimated light-curve parameters through a simulation approach. We used the forest stand data derived from repeated measurements of three permanent plots. The posterior distribution of light-curve parameters derived from MCMC were well converged. We virtually applied three thinning scenarios, upper thinning, random thinning and lower thinning, and then simulated stand growth. The modified model could well reflect the changes in canopy structure derived from thinning on the growth pattern after thinning. The results suggest that the multiple light-curve model adopted in this study would be represent more realistic stand dynamics after thinning than single light-curve model adopted in the former model.
