Cambios de cobertura/uso del suelo en una porción de la Zona de Transición Mexicana de Montaña Coverage/land use changes in a portion of the Mountainous

The Southwest region of the State of Mexico ( PSEM as it stands in Spanish) is located in the so called Mexican Transition Mountainous Zone. The forest communities that prevail in this area are pine trees forests ( Pinus spp.), oak trees forests ( Quercus spp.), mixed ones, mountainous cloud forest and tropical deciduous forest, which are being modified due to the influence of human processes. This research paper establishes a methodology to analyze the changes on the land cover of the PSEM which took place from 1989 to 2009 using a technique of image satellite interpretation (Landsat TM), as well as the use of the maximum authenticity algorithm which leads towards the implementation of soil and vegetation maps whose main purpose is to obtain information on the validity of these study cases.
