This papers is a methodological essay that was made within the frame of Landscape Ecology, which lets us see the relation among the different environmental elements, in a systematic and integral way, enabling the knowledge of the structure and functioning of a well-limited geoecosistem as in the case of the no Temascaltepec Basin. Some environmental indicators were used for the central part of the development of the work: the energetic efficiency of rainfall, the cushioning capacity of the plant cover and the density of surface drainage, by means of whose evaluation it was possible to define the organization and hierarchy of the elements and components represented in cach of the geoecological units. As a final result, five ecological units were identified, of wich the first tree -composed of the high mountain barren land (paramo), the cold highland and the mountain valley- still maintain a strong structural, functional and morphoclimatic relationship a strong structural, functional and morphoclimatic relationship that allows a low rate of hydric erosion and consequently the maintenance of a high stability. The other two units are spatially and functionally independent of these, the intermediate Temperate Land maintains a moderate hydric erosion, wich confers to it a moderate stability Finally, it was determined that the lowland and the hilly warmlands shows low rate of erosion achieving a high stability.
