As proposed by Michael Godet, an Structural Analysis exercise applied to achieve a representation of the system as close to reality as possible, and reducing its complexity to its essential macrovariables in the research on sustainable tourist called "Ruta del Oro" in Nariño Colombia, which seeks to conjugate the geologic mining patrimony with other resources existing in the field. It was discovered that the macrovariables that determine the system are the geology, the geomorphology and the climate; those on which it is possible to intervene to equilibrate it are, the water, the territorial structure, the vegetation and to a lesser extent, the soil. The dependent macrovariables are the landscape, the cultural resources and the fauna. These results were contrasted with the correspondent cartography, secondary information and fieldwork. It is concluded that the macrovariables of the investigation and the role identified each one are the adequate.
