CAMBIOS EN EL PROCESO DE EROSIÓN. EL PARQUE OTOMÍ –MEXICA, ESTADO DE MÉXICO (2014 Y 2018)

The Otomi - 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.
