Man-nature relationship and that one of social groups among themselves, as well as the form of natural resources ownership, are determinant factors of the environment current state and of society life quality. This thesis aimed at analyzing Sergipe coastal plain sandbank landscape environmental changes. The spatial area of this analysis was Sergipe coastal plain, located in nine coastal counties bordering sea, namely: Brejo Grande, Pacatuba, Pirambu, Barra dos Coqueiros, Itaporanga D Ajuda, Estância, Santa Luzia do Itanhy e Indiaroba, grouped into three coast sectors (north, center and south). This study methodology is set upon four stages: documentary fieldwork, laboratory and synthesis. The theoretical-methodological model is the GTP (Geosystem, Territory, Landscape). Bertrand (2007), as this corroborates the idea of having an integral holistic vision, in opposition to the compartmentalized analysis, merely descriptive. Doing environmental research, from a method involving the intrinsic relationship between society and nature, is the innovative challenge of Geography. Among the obtained results, there was a concept that sandbank, in geographical sense, is part of the coastal plain, except for beach, dunes, tômbolos, among other sub-environments, covered or not by vegetation, and especially occupied or not by man, having as internal boundary the coastal plains (Barreiras Group). The study of the landscape physiology allowed one to visualize that landscape transformation by man represents one of the main elements in its formation. It was also possible to apply GTP in the study area. A geosystem (Coastal Plain) with seven territories and two landscape classifications with five major subdivisions was visualized. One reaches the conclusion that Bertrand s model enabled a better understanding of the area, for the integrated analysis, from the socio-environmental perspective that comes from such model, allowed one to see and analyze all spatial area phenomena, enabling a better understanding of Sergipe coastal plain sandbank landscape environmental changes. The presence of Hancornia speciosa Gomes in Sergipe is linked to environmental conditions required by this species, which is found in the study area and also to the reasons expressed in the Refuges Theory from AB Sáber. Currently, sandbanks have been the target of such explosive real estate speculation, which has transformed the natural landscape into a mosaic landscape, meaning, into a disturbed and fragmented landscape, in short term, where the climatic variability produce significant environmental changes when compared to the intensity of human actions.
