Actualmente, el método más usado para estratificar las masas forestales se basa en la fotointerpretación, lo cual implica un alto grado de discrecionalidad que afecta a los parámetros que dependen principalmente de la rodalización para calcular las existencias volumétricas, el área basal, etcétera. Para contribuir al manejo forestal sustentable es necesario conservar la misma delimitación de las unidades básicas de manejo, en particular los rodales, mediante la unificación de criterios técnicos que permitan lograr un buen seguimiento. El objetivo de este trabajo fue comparar dos técnicas de rodalización: una de fotointerpretación y otra semiautomatizada, desarrollada en el presente estudio, basada en el análisis geomorfométrico de generación de cuencas hidrológicas, a partir de tres Modelos Digitales de Elevación (Inegi, ASTER y SRTM) y el uso de técnicas de Sistemas de Información Geográfica, con el software ArcGIS 10.0. Se utilizaron datos de 51 polígonos de predios bajo aprovechamiento forestal de la Sierra Madre Occidental. La comparación estadística entre los valores medios de los estadísticos de zona generados a través de fotointerpretación, y de aquellos obtenidos de forma semiautomática, no mostraron diferencias significativas en la exposición (p&gt;0.05), mientras que la elevación y la pendiente registraron estimaciones estadísticamente distintas (p&lt;0.01). Se concluye, que la rodalización generada a partir del método semiautomatizado permite obtener delimitaciones homogéneas de rodales en cuanto a la altitud, pendiente y exposición, independientemente del MDE utilizado.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The management units established in the management plans, according to the guidelines established in Mexican Official Standard NOM-152-SEMARNAT-2006, are the stands and the subcompartments. Currently, the method most commonly used to stratify the forest is based on photointerpretation, which involves a high degree of discretion that affects the estimates of parameters that depend mostly on the stand area, such as growing stock, basal area, among others. In order to contribute to sustainable forest management, it is necessary to maintain the same delimitation of the management units, in particular of the stands, unifying the technical criteria to guarantee its adequate monitoring. This work had the goal of comparing two stand delimitation techniques: i) the traditional method, based on photointerpretation, and ii) a new method developed in this study, derived by means of a semi-automated technique based on a geomorphometric analysis of watersheds generated from three Digital Elevation Models (Inegi, ASTER y SRTM), using procedures of Geographic Information Systems (SIG), mostly the ArcGIS 10.0 software. Data of 51 forest properties located in the Sierra Madre Occidental of the state of Durango were used. The results of the statistical comparison among the mean values of the elevation, slope and exposure variables obtained by the photointerpretation method and those generated by the semi-automated technique did not show significant differences in the exposure variable (p&gt; 0.05), while for the elevation and slope variables the differences were statistically significant (p &lt;0.01). Study findings concluded that the stands generated by means of the semi-automated technique allows the generation of homogenous stands in terms of the characteristics of elevation, slope and aspect.]]></p></abstract>
