Abstract: The environmental planning in hydrographic micro basins may minimize the incidence of environmental impacts as consequence of the human indiscriminate action.The hydrographic basin is worldly recognized as the best unit for handling natural resources.Thus, a methodology for diagnosis of the real situation of natural resources, in a basin, turns to be a necessary tool for the preservation and management of these resources.The identification of the different kinds of predominant vegetables informs, chiefly, about the level of soil protection, since the vegetation is responsible for the protection against the impacts of the raindrops (splash), by the reduction of the speed of surface outflow (runoff), through the increasing of the land ruggedness and greater soil structure constitution that may offer greater resistance to the action of the erosive processes.Besides, the collected data about the covering vegetation generally comes along with the information about the current use of the soil, since they both are strictly related.Several authors have pointed out the importance of geo morphological mappings of environmental planning projects.The use of the cartography and geo morphological information aim to represent the physiography of the landscape, area, are beginning to adopt the direct planting system.However, it is necessary to guide the human occupation in order to keep safe the areas intended to be of environmental preservation, aiming the conservation of the natural resources, the strong environmental fragility and high susceptibility to erosion of this area of study.
