Abstract
El objetivo de la presente investigación es conocer y evaluar los niveles de modificación
antrópica sobre la cobertura vegetal de los paisajes del estado de Chiapas, México. Para cumplir
con este objetivo se aplicó un índice de presión al mapa de los paisajes físico-geográficos del
estado de Chiapas, a escala 1: 250 000. Los resultados indican que la categoría baja ocupa el 29%
de la superficie estatal; la clase alta 27%; el nivel medio 26%; la categoría muy baja 16%;
finalmente, el nivel muy alto abarca 2%. La categoría alta se ubica en paisajes de planicie,
piedemonte y valle, en clima cálido húmedo y cálido subhúmedo. La clase baja se localiza en
montañas de origen tectónico-intrusivo, tectónico-acumulativo y tectónico-kárstico, en climas
templado, semicálido húmedo a subhúmedo y cálido húmedo. El escenario de tendencia es
preocupante, porque la categoría alta podría representar en el corto plazo 53% de la superficie
estatal.
The goal of this research is to understand and evaluate the levels of anthropic transformation on the vegetation cover in the landscapes of Chiapas, Mexico. To achieve this goal, a pressure index was applied to the map of the physical-geographical landscapes of the Chiapas State, in a 1: 250 000 scale. The results indicate that low category occupies 29% of the surface area of the state; the high class 27%, the medium level 26%, the very low category 16%; finally, the very high level covers 2%. The high category is located in plains, piedmonts and valley landscapes in warm humid and subhumid climate. The low class is located in mountains of tectonic-intrusive, tectonic-acumulative and tectonic-karstic origin, in temperate, semiwarm humid to subhumid, and warm humid climates. The trend scenario is worrisome, because the high level could represent in the short term 53% of the surface area of the state.
