“…For example, the 3-PG (Physiological Principles in Predicting Growth) is a simplified process-based model that is designed to predict the growth, diameter distribution, and annual mortality for individual forest stands (Landsberg and Waring, 1997). However, the model does not include a soil component or feedbacks between the aboveground and belowground.…”

“…The carbon balance-based growth model used in this study was derived from the 3-PG (Physiological Processes Predicting Growth) model developed by Landsberg and Waring (1997). The model consists of the following six processes ( Figure 1): (1) photosynthetically active radiation absorption; (2) photosynthetic production; (3) photosynthetic rate control by temperature and humidity; (4) respiration; (5) litterfall and turnover; and (6) growth partitioning.…”

“…Processbased growth models consist of functions that describe the interactions between trees and their environment, as such, they can represent changes in growth patterns based on changes in the climatic condition (e.g. Kurz et al, 2009;Landsberg and Waring, 1997;Pretzsch, 2010). Several processbased growth models have been developed and are utilized for revealing good forest management practices (e.g.…”

Abstract:This paper aimed to reveal differences in growth response to climatic condition between sugi (Cryptomeria japonica) and hinoki (Chamaecyparis obtusa) by comparing parameters of a carbon balancebased growth model. Seven carbon balance-based growth model parameters related to the rate of photosynthesis, temperature and humidity controls were parameterized by a Bayesian calibration using growth data derived from permanent plots. A hierarchical Bayes model was applied to this parameterization, where the common parameter was estimated first and the species-specific parameters were derived from the common parameter thereafter. Simulated light-response curves using estimated parameters were similar and the photosynthetic rate of sugi was higher than that of hinoki. The patterns of response to temperature represented by estimated parameters were different between sugi and hinoki; sugi responded rapidly to changes in temperature while hinoki responded relatively slowly, resulting in a higher tolerance to low temperature than sugi. Estimated parameters indicated that the photosynthetic rate controlling function for humidity could not be implemented for either species in the model. The parameterization of a carbon balance-based growth model revealed differences in the potential photosynthetic ability and response to temperature of sugi and hinoki. However, we could not represent the control effect of humidity on the photosynthetic rate.

Однако для анализа эффективности плантационного лесоразведения и искусственного восстановления лесов после сплошных рубок, лесных пожаров и других интенсивных воздействий необходимо дополнительно учитывать комплекс лесохозяйственных мероприятий, которые способны в значительной степени регулировать интенсивность продукционного процесса [6,7].…”

The main objective of this study was to assess the biomass productivity of short-rotation forest plantations depending on different spacing between trees. Our simulations were focused on the birch plantation with the initial density of 2500 trees·ha-1, which could be reached by using two planting schemes: with the distances between trees in a row and between rows, respectively, 2 and 2 m or 1 and 4 m. We used the model EFIMOD-fbp-REG, and the soil-climatic data relevant to the Eutric Podzoluvisols disposed in the Republic of Mariy El in the Eastern part of European Russia. The results showed greater biomass of trees in the planting scheme of 1 × 4 m. With the scheme of 2 × 2 m, increments of diameters and heights of most trees decreased at the age of 15–20 years, and then the total number of trees strongly reduced. Intensive death of trees with the scheme of 2 × 2 m was due to the procedure simulating the self-thinning of trees, which was used in the model. It is based on the use of the threshold ratio of an annual biomass increment of the tree to the total tree biomass, IP/BT. With the planting scheme of 2 × 2 m, the almost simultaneous closing of crowns and root areas of neighboring trees in rows and between rows was the cause a competition for light and for available soil nitrogen, and resulted in a sharp reduction of biomass increments. As a consequence, the value of IP/BT was below the threshold. With the planting scheme of 1 x 4 m, step-by-step (or gradual) closing of crowns and root areas of trees (first in the rows and then between rows) reduced the competition effects, that ensured a higher growth rate of the tree stand in the next years.
