Coverage/land use changes in a portion of the Mountainous Mexican Transition Zone
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...

description | 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. Overlapping those maps, it is possible to come up with a matrix of changes to check annual modifications on the land cover, and based on it the changes rates can be measured. From data obtained through this research, it can be stated that the land cover of this forest has considerably decreased because 19 262 ha disappeared and were taken up by water supplies (105 ha), farming lands (19 113 ha), human settlements (39 ha) and technical and controlled agriculture (5 ha). It can be summed up that this deforestation mainly comes as a result of the practice of agriculture and livestock activities indeed. |

La Porción Surponiente del Estado de México (PSEM) se ubica en la Zona de Transición Mexicana de Montaña. Las comunidades forestales que predominan en este territorio son bosques de pino (Pinus spp.), encino (Quercus spp.), mixtos (Pinus spp. - Quercus spp. y Quercus spp. - Pinus spp.), mesófilo de montaña y tropical caducifolio, los cuales están siendo modificados por la influencia de procesos antropogénicos. Este estudio presenta el análisis de los cambios de cobertura y uso del suelo ocurridos entre 1989 y 2009 en la PSEM, a través de la interpretación de imágenes de satélite (Landsat TM), que en complemento con la aplicación del algoritmo máxima verosimilitud permitieron la construcción de mapas temáticos de uso de suelo y vegetación, los cuales fueron evaluados para conocer su confiabilidad temática. A partir de la sobreposición de estos mapas se elaboró una matriz de cambios que comprende la superficie de las coberturas y usos del suelo para cada año y con base en esta se determinaron las tasas de cambio. Los resultados obtenidos demuestran que la cobertura del bosque disminuyó considerablemente, es decir, se eliminaron 19 262 ha, las cuales fueron ocupadas por las categorías cuerpos de agua (105 ha), agropecuario (19 113 ha), asentamientos humanos (39 ha) y agricultura tecnificada controlada (5 ha). La superficie deforestada es resultado del establecimiento y la práctica de actividades relacionadas con la agricultura y ganadería.
