This study has guided the analysis on concept of landscape in systemic perspective and understand there’re elements that interact in complex ways. Areião Beach shows a peculiarity. Thus, the study was made to understand elements that act in southwestern part of the coastal zone of this island, where is located the search area. In one hand, physical elements are analyzed at landscape, such as waves action, wind, tides, vegetation and rainfall, in other hand, the influence of anthropogenic elements are analyzed such as the pier, the effluents and process of using and occupation. Nevertheless, some steps were followed to understand Areião Beach landscape elements in this study. The first step was to create a theoretical-conceptual reference in geography concepts, following the objectives of this work. There’s adopted the classification of Landscape Units proposed by Bertrand (1972). Later it was understood the structure of the landscape, showing the facts of study area on spatial distribution in maps. Four diferent parts were delimited at the beach. After, the seasonality was evidenced by the physiology of landscape and it was highlighted in the analysis guiding interpretations of data variability of morphology and granulometry, as well as their interactions with anthropogenic elements. At this time, the pier’s influence in landscape’s identified. It is believed that pier creates a buffer zone, where tidal action is attenuated to erosional processes that reach the beach. Furthermore, granulometric analysis and the degree of selection showed that there were two sediment transporting cell. The first before the pier, where are the profiles 1 and 2 was located. And the second one after pier, where profile 3, 4 and 5 were located. So Areião Beach was classificated in landscape units. The beach was rated on Geosssistema’s scale, being subdivided into geofacies Ie, IIa1, IIa2, IIa3, IIIe, IIIa, IVa and IVe. At each definition of geofacies we wanted to point, in a spatiotemporal scale of detail, the interrelationship between the physical and anthropogenic active in each landscape unit. The morphology and granulometri data were crossed with qualitative analysis developed through observations in locu to complete the definition.
