Variabilidad espacio-temporal de la cobertura terrestre en la cuenca del río Tecolutla, México

Abstract

En este estudio, el cambio de cobertura se caracterizo desde la Geomatica, aplicando un metodo de modelado conceptual que permitio efectuar una abstraccion espacial util para identificar los elementos fundamentales del sistema territorial analizado y sus interrelaciones. Aplicando imagenes satelitales Landsat (5, 7, 8), correspondientes a los anos 1984, 1994, 2004 y 2014, cubriendo un periodo de 30 anos. Se aplicaron correcciones radiometrica y atmosferica, y se obtuvieron las clasificaciones supervisadas. Como resultado se obtuvieron indices Kappa de 0.74-0.85, indicando una muy buena precision. Los principales resultados en la cuenca en los 30 anos analizados son: la cobertura agricola paso de 24 a 42% y su tasa de cambio anual (TCA) fue de 1.86%. Poblado fue la clase mas dinamica (TCA 8.8%). Forestal paso a agricola en 54%, matorral a pastizal en 46% y a agricola en 41%.
