Abstract
El Parque Otomí – Mexica es un área natural protegida con importantes impactos sobre la
cobertura vegetal, que causan erosión del suelo. Este estudio analiza la retención del suelo por
medio de la Ecuación Universal de Pérdida de Suelos (RUSLE). La metodología consta de la
cuantificación y localización de los siguientes procesos: 1) Erosividad de la lluvia (Factor R), los
datos se obtuvieron de ocho estaciones meteorológicas ubicadas dentro del área de estudio; 2)
Erosionabilidad del suelo (Factor K), se obtuvo la información de cartas edafológicas del INEGI
2014 – 2018; 3) Longitud y pendiente del terreno (Factor LS), se representaron las curvas de nivel
a partir de la carta topográfica E14A-48 del INEGI; 4) Cobertura vegetal (Factor C) se realizó
clasificación, cuantificación y representación cartográfica de las coberturas vegetales para los
años 2014 y 2018 a partir de la carta de uso del suelo del INEGI. Los resultados muestran que, en
las áreas con menor longitud de pendiente, menor precipitación, tipo de suelo menos erosionable
y mayor cobertura vegetal, la erosión es menor; por el contrario, en las zonas con mayor longitud
de pendiente, mayor precipitación, tipo de suelo más erosionable y menor cobertura vegetal, se
presenta mayor nivel de erosión.
The Otomí - Mexica Park is a protected natural area with significant impacts over the vegetation cover, causing soil erosion. This study analyzes soil retention through the Universal Soil Loss Equation (RUSLE). The methodology consists of the quantification and location of the following processes: 1) Erosivity of the rain (Factor R), the data were obtained from eight meteorological stations located within the study area; 2) Erosionability of the soil (K Factor), the information was obtained from edaphological charts of the INEGI 2014 - 2018; 3) Length and slope of the terrain (Factor LS), the contour lines were represented from the topographic chart E14A-48 of the INEGI; 4) Vegetation cover (Factor C), classification, quantification and cartographic representation of the vegetal cover was carried out for the years 2014 and 2018 based on the INEGI land use charter. The results show that, in the areas with less slope length, less precipitation, less erodible soil type and greater vegetal cover, erosion is lower; on the contrary, in the areas with a greater length of slope, greater precipitation, more erodible soil type and less vegetal cover, there is a higher level of erosion.
