Resumen
Los ríos son de los ecosistemas más afectados por las actividades del ser humano; por ello, es
necesario evaluar las condiciones de los mismos y su entorno; por esto el objetivo de este estudio
es caracterizar la cobertura vegetal y usos de suelo dentro de la franja de protección a lo largo del
cauce río Copey. En dos visitas de campo (2013) se recorrió el cauce del río generando puntos de
control geoposicionados de las categorías de usos de suelo, variaciones en la vegetación y toma de
fotografías, luego por medio de fotointerpretación de imágenes a juicio de expertos se generaron
tres mapas, además de gráficos de caracterización de la vegetación de tres zonas. Se categorizaron
11 tipos de uso de suelo, en donde predomina el bosque denso. En la parte alta predomina la cobertura
boscosa, en la parte media pastizales con borde arbustivo y en la parte baja infraestructura
urbana. La principal conclusión es que existe gran área sin infraestructura urbana ni vegetación, por
lo que es de gran potencial para esfuerzos de restauración.
Rivers are considered one of the ecosystems most affected by humans. This is why it is important to evaluate the conditions of rivers and their environment. The purpose of this research is to characterize the vegetation cover and land use within the buffer zone along the Copey river. In two field trips (2013) we hit the river course to generate control geopositioned points coverage, vegetation variations and photographing. Then, we used the photo-interpretation method, by the expert judgment, and then generated three coverage maps. Additionally, we generated DAP, characterization height of trees in tree river zones. We categorized 11 coverage types, where the predominant coverage was the dense forest. The upper side is the one with the greatest forest cover. Shrubby grasslands edge predominates in the middle side, and the lower side begins to present urban infrastructure. We concluded that there is a large area devoid of vegetation, without urban infrastructure, which indicates that it is one of the areas with the greatest potential for restoration efforts.
