| description | Wildland fires are a fundamental process that shape and maintain the structure of forest ecosystems, and are the result of several environmental and socio-economic factors that interact at the landscape scale to produce specific spatial distribution patterns. The aim of this study was to characterize fire-hotspots patterns and identify the main environmental and anthropogenic factors influencing their density in the Sierra Madre Oriental of San Luis Potosí in the period 2000-2012. The inhomogeneous Ripley´s K function was used to characterize monthly spatial patterns of fire hotspots (second order effects). To identify the main variables and thresholds that best explained the occurrence of fire-hotspots, regression trees were built using kernel density (first order effects) as a continuous response variable. Evidence of aggregated, regular and random patterns was obtained at different spatial scales. Monthly rainfall, diurnal temperature, land use/cover, elevation, distance to populated areas and distance to unpaved roads had a high influence in the occurrence of fire hotspots. Our results can contribute to a better understanding of wildland fire dynamics in the study area and can be used for studies related to forest fire danger and risk by applying the thresholds of the main explaining variables. |

Los incendios forestales forman parte fundamental de los procesos para la conformación y el mantenimiento de los ecosistemas terrestres. La manera en que los incendios se manifiestan espacialmente y temporalmente es de vital importancia para entender su dinámica en el paisaje. El objetivo de este trabajo fue caracterizar los patrones espaciales de los puntos de calor e identificar los factores ambientales y de origen humano que influyen en su densidad en la Sierra Madre Oriental de San Luis Potosí en el periodo 2000-2012. Se empleó la función no-homogénea derivada de la función K de Ripley para caracterizar los patrones espaciales de los puntos de calor (propiedad de segundo orden). Para identificar las variables ambientales y antropogénicas que más influyen en ocurrencia de puntos de calor, se estimó la función de densidad kernel (propiedad de primer orden) y se usó como variable de respuesta continua para generar árboles de regresión. Se obtuvo evidencia de patrones espaciales agrupados, aleatorios y regulares en diferentes escalas. La precipitación pluvial, la temperatura diurna, la vegetación y el uso del suelo, la altitud, la distancia a asentamientos humanos y a terracerías tuvieron una alta influencia en la densidad de puntos de calor. Los resultados pueden ayudar al entendimiento de la dinámica de incendios forestales y pueden ser utilizados para estudios de peligro de incendios mediante la aplicación de los umbrales detectados para las variables explicativas.
