Spatial modeling of basal area and tree volume in managed Pinus patula and P. teocote forests in the ejido Atopixco, Hidalgo
Basal area (AB m2/ha) and tree volume (VOL m3/ha) were modeled for even-aged Pinus patula and P. teocote forest stands located in Hidalgo, Mexico. Variables such as tree crown cover (COB), field recorded Leaf Area Index (LAI5 m2/m2), allometric Leaf Area Index (LAIAL m2/m2) ; GIS variables and refle...

| description | Basal area (AB m2/ha) and tree volume (VOL m3/ha) were modeled for even-aged Pinus patula and P. teocote forest stands located in Hidalgo, Mexico. Variables such as tree crown cover (COB), field recorded Leaf Area Index (LAI5 m2/m2), allometric Leaf Area Index (LAIAL m2/m2) ; GIS variables and reflectance data derived from a multispectral SPOT 5 image were used as independent variables. Environmental conditions were characterized by digitizing the INEGI’s chart of climatic effects (scale 1: 250 000) and processing the Digital Elevation Model (MDE) of the study area. A geographic information system (GIS) was set up with variables such as Elevation, Slope’s angle and aspect, Temperature, Precipitation, SPOT derived spectral bands, and two sets of vegetation indices based either on a) the ratio of spectral bands (NDVI and CTVI) or on b) the spectral distance between vegetation and bare soil (PVI and SAVI). Multiple linear regression models were fitted based on field and GIS data. AB was significantly related to LAIAL, Mean Annual Temperature (TMA), ALTITUD and SPOT Band 4 reflectance (P < 0,001, R2 = 0,9662). VOL was significantly related to LAIAL, Mean Annual Temperature (TMA) and ALTITUD (P < 0,001, R2 = 0,8856). |

VOL was significantly related to LAIAL, Mean Annual Temperature (TMA) and ALTITUD (P < 0,001, R2 = 0,8856). Se modeló el área basal (AB m2/ha) y volumen de madera (VOL m3/ha) de rodales coetáneos de Pinus patula y P. teocote localizados en Hidalgo, México, utilizando variables de porcentaje de cobertura arbórea (COB), índice de área foliar en sitio (LAI5 m2/m2) y alométrico (LAIAL m2/m2), variables cartográficas y de reflectancia obtenidas de una imagen multiespectral del satélite SPOT 5 . Para la caracterización de las condiciones ambientales se digitalizó la carta de Efectos Climáticos (escala 1: 250 000) de INEGI y el Modelo Digital de Elevación (MDE) correspondiente a la zona. Se integró un Sistema de Información Geográfica (SIG) constituido por las siguientes capas de información: altitud, pendiente, exposición, temperaturas, precipitaciones, bandas espectrales, y dos grupos de índices de vegetación basados en a) la relación espectral de bandas (NDVI - CTVI) y b) la distancia espectral entre vegetación y suelo desnudo (PVI – SAVI) . Con datos de campo y del SIG se ajustaron modelos de regresión lineal múltiple. Para el AB la relación más significativa fue con LAIAL, Temperatura Media Anual (TMA), ALTITUD y la Banda 4 de SPOT (P < 0,001, R2 = 0,9662). Para el VOL la relación más significativa fue con LAIAL, Temperatura Media Anual (TMA) y ALTITUD (P < 0,001, R2 = 0,8856).
