Abstract

ABSTRACT Sectional equations and mathematical volume models are a reliable way to estimate carbon sequestration and storage, which is a key foundation for forest management and conservation. The objective of this study was to assess stem volume and form factor through the classical sectional method to then, using five regression models commonly used for forest management, identify the most suitable mathematical model to estimate the stem volume in a commercial forest plantation (CFP) of Pinus pseudostrobus Lindley in the Comunidad Indígena de Nuevo San Juan Parangaricutiro, Michoacán, in Western Mexico. By using 10, 15 and 20 yr.-old sampling points and two sampling methods (destructive and nondestructive), we found a form factor 0.42, 0.48 and 0.51 and stem volume of 0.098 m3, 0.400 m3 and 0.804 m3 for the three ages assessed, which presented diameter classes (DC), from 10 to 45 cm. The mathematical models identified that age of plantation determines stem volume and form factor, and the models that best fit volume estimation were the Schumacher-Hall model and the Australian model with an R2 adj range between 0.89 and 0.99. Estimation of stem volume is of vital importance to assess the income generated by the timber industry, and relevant for forest conservation, management, and carbon sequestration studies.

年龄对墨西哥西部商业林人工林中假strobus Lindley松体积估算和形状因子的影响

截面方程和数学体积模型是估算碳固存和储存的可靠方法，是森林管理和保护的关键基础。本研究的目的是通过经典的截面方法评估树干体积和形状因子，然后使用五个常用于森林管理的回归模型，确定最合适的数学模型来估计新圣胡安Parangaricutiro Indígena社区的Pinus pseudostrobus Lindley商业林（CFP）的树干体积，墨西哥西部的米却肯。通过使用10年、15年和20年前的采样点和两种采样方法（破坏性和非破坏性），我们发现三个年龄段的形状因子分别为0.42、0.48和0.51，茎体积分别为0.098 m3、0.400 m3和0.804 m3，呈现直径等级（DC），从10到45 cm。数学模型确定，种植年龄决定了茎体积和形状因子，最适合体积估计的模型是舒马赫-霍尔模型和澳大利亚模型，R2 adj范围在0.89和0.99之间。树干体积的估计对于评估木材行业产生的收入至关重要，并且与森林保护、管理和碳固存研究相关。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
