%X although mexico city has one of the highest population densities worldwide, 58% of its territory has been catalogued as "conservation soil". the present study carried out a spatial dimensional analysis - of both land use and vegetation cover type - of the area known as the "magdalena contreras" watershed. the analysis resulted in the identification of 20 different classes with a prevailing presence (40%) of abies religiosa upon 34% of closed forest and 6% in of open forest type. the second most extended vegetation cover (20%) is that of pinus hartwegii distributed as well in both open (10.8%) and closed (9.68%) forests. the third most extensive forest type (13.6%) is that conformed by the so-called ecotonal forest encompassing both a. religiosa and p. hartwegii, 12.95% of which is located in a closed forest and 0.66% in an open forest. at last, the closed forest conformed by p. hartwegii and a. religiosa represents a 6.45%, the mixed forest a 4.8% and the quercus forest a 2%. by crossing geographic information generated a environmental matrix, which allowed for an environmental analysis of the key components needed, to know the area and location of each of the vegetation cover as a function of temperature, precipitation, elevation, edafology and aspect.
