Zusammenfassung:Studying the relief through morphological analysis allows typifying forms, elements and structures of the karst relief that help in the understanding of the genesis, evolution and dynamics assumed by the erosion of the Red Ferrallitic soils. It is a particularly important circumstance in the Southern karst Plain Havana-Matanzas, to understand how and why certain information is preserved and others are lost as the research is carried out from one scale to another, which has led to certain myths and uncertainties about the degradation processes of these soils. The present work aims to analyze the complex influence of relief and geographic scale on the understanding of karst-erosive processes in the areas of influence of karst depressions from a baseline of more than three decades, which demonstrates the unidirectional advance of karst-erosive dynamics in accordance with the conditions of use and management to which they have been subjected. It is concluded that the recognition and spatio-temporal evolution of erosion forms is only possible at a local scale and not from a simple rescaling of the variables to large areas, in order to avoid different interpretations in the erosion maps of the Red Ferralitic soils in Cuba. Key words: degradation, karst, relief. Estudiar el relieve a traves del analisis morfologico permite tipificar formas, elementos y estructuras del relieve karstico que auxilian en el entendimiento de la genesis, evolucion y dinamica que asume la erosion de los suelos Ferraliticos Rojos, circunstancia particularmente importante en la Llanura Karstica Meridional Habana - Matanzas, para comprender como y porque cierta informacion es preservada y otra se pierde conforme la investigacion se ejecuta de una escala a otra, lo que ha propiciado ciertos mitos e incertidumbres sobre los procesos de degradacion de estos suelos. El presente trabajo tiene como objetivo analizar la influencia compleja del relieve y la escala geografica en la comprension de los procesos karstico - erosivos en las areas de influencia de las depresiones karsticas, a partir de una linea base de mas de tres decadas, que demuestra el avance unidireccional de la dinamica karstico - erosiva, en conformidad con las condiciones de uso y manejo a que han estado sometidos. Se concluye que el reconocimiento y evolucion espacio - temporal de las formas de erosion solo es posible realizarla a escala local y no a partir de un re-escalamiento simple de las variables a grandes areas, para asi
