2011年8月1日 · Completely updated and expanded new edition of this widely cited book, Modelling Forest Growth and Yield, 2nd Edition synthesizes current scientific literature, provides insights in how models...

2015年7月14日 · In this study, we developed a forest growth and yield model that can be used to predict individual-tree growth under current and projected future climatic conditions. The model was constructed by integrating historical tree growth records with predictions from an ecological process-based model using neural networks.

In North America, forest growth and yield prediction models began as simple estimates of standing vol-ume (Pinchot, 1898) and progressed to estimates using increment cores (Fenska and Lauderburn, 1924). These studies and others led to stand table projection systems still in use as a basic form of empirical forest-growth modelling.

It was developed to bridge the gap between conventional, mensuration-based growth and yield, and process-based carbon balance models. The output variables it produces are of interest and relevance to forest managers. 3-PG calculates the radiant energy absorbed by forest canopies and converts it into biomass production. The efficiency of ...

Foresters recognize that it is necessary to take climatic variation into account to predict the growth of forests and conditions that make them vulnerable to natural disturbances. Scientists have constructed computer simulations models to address this challenge.

2019年4月1日 · In general, the simple forest growth model 3-PG delivers practical outputs, which are directly used in forest management. Additionally, the functions and applications of the 3-PG/3-PGS/3-PGmix model could be explored to deal with the impacts of climate change on forests and to ensure the sustainable management of forests.

2023年6月15日 · To identify the current trends in forest modelling, we first carried out a search in the Web of Science database (https://www.webofscience.com/wos/woscc/advanced-search) for the years 2018 to 2022 using the terms “forest modelling,” “forest function,” “forest distribution,” “forest adaptation,” and “modelling forest function ...

2020年8月28日 · Process-based forest models (PBMs) are important tools for quantifying forest growth and vulnerability, particularly under climate change. The 3-PG model (Physiological Processes Predicting Growth) is one of the most widely used forest growth simulators for this purpose worldwide.

2022年4月1日 · The 3-PG2Py/3-PG2 model is a simplified process-based, and stand-level deterministic forest growth model and can be used to predict forest gross primary production, water balance, evapotranspiration rate, stem number, and …

2002年1月1日 · Three different forest growth models were compared in simulating growth of Scots pine. A yield table approach, the process-based 3PGN model, and a Stand Level Dynamic Growth (SLeDG)...
