Abstract	The study proposed to characterize in an integrated way the physical-natural aspects of the landscape of the Parque Nacional de Sete Cidades associated to the field work, from the lithological, geomorphological, climatic, hydrographic, pedological and physiognomy elements of the vegetation cover. The present activity consisted of the following steps: 1) planning; 2) laboratory activities; 3) Fieldwork (June 17, 2017). Therefore, it was possible to understand that the geological structure of the area is predominantly arenite, whose geomorphological features come from the physical weathering - generating particularly flat plateaus, tables and abrupt escarpments - with altimetric dimensions varying from 128 to 279 m and flat relief to smooth occurs in 74.4% of the area. The drainage is quite irregular due to the climatic conditions, being the Riacho Riachao its main fluvial course. The area is under the influence of the Intertropical Convergence Zone (ITCZ), with an average precipitation of 1,337 mm per year and a rainy period concentrated between January and May. Soils are predominantly young and undeveloped, namely: Plinthsols and Neosols. These are mostly covered by open cerrado broadleaf perennial and medium cespitoso graminoid field in 47.42% and 35.84%, respectively. This information is part of the biophysical framework and the fieldwork allowed visualizing it in the light of the systemic approach.
