摘要

直径和高度是森林清查中确定森林中储存量的关键参数。这项研究的目的是为八个联邦实体生成一个方程，以便准确估计该国中部和南部Abies religiosa的木材量。大约2747棵树被用来调整总树卷体积、枝条体积和总树体积（vrta、vramas和vta）的方程。为选择最佳模型制定了以下标准；调整后的决定系数、偏差、平均误差；以及残差的图形和数值分析。由于缺乏关于树枝的信息，对于特拉斯卡拉州和韦拉克鲁斯州，只获得了总的树木滚动量。方程产生的拟合优度是可靠的，因为它对因变量的解释率超过93%，误差小于0.47m。这些表达式是

Estimación de volumen de Abies religiosa (Kunth) Schltdl. & Cham. en diferentes entidades federativas de México

Diameter and height are crucial parameters in forest inventories to determine the volume that is stored in the forest. The objective of this research was to generate an equation for eight federative entities that allows an accurate estimate of the timber volume of Abies religiosa in the center and south of the country. Around 2,747 trees were used to adjust equations of total tree roll volume, branch volume and total tree volume (vrta, vramas and vta). The following criteria were set for the selection of the best model; adjusted coefficient of determination, bias, mean error; as well as the graphical and numerical analysis of the residuals. Due to the lack of information on the branches, for Tlaxcala and Veracruz states only the total tree roll volume was obtained. The goodness of fit generated by the equations is reliable, since it explains more than 93% to the dependent variable, the errors are less than 0.47 m. These expressions are

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
