Part of the issue - how it gives the uses implied by the spatial distribution of salt in the current historical period, known by some geographers as technical-scientific-informational. The way taken to answer this research was through readings of researches already carried out, field research in government agencies, the use of photographs, questionnaires and interviews. The search for data on production salting, their handling and marketing was one of the methodology steps. The result of this research was the perception of the dynamic activity of salting and uses transmitted within the city of Macau / RN, and the state of Rio Grande do Norte. / O presente trabalho trata-se de uma pesquisa sobre o circuito espacial de produ??o de sal e os usos implicados pelas ind?strias salineiras potiguar, especificamente, do munic?pio de Macau/RN. Parte da quest?o - em que medida se d? os usos implicado pela espacializa??o do sal no per?odo hist?rico atual, conhecidos por alguns ge?grafos como t?cnico cient?fico informacional. O caminho trilhado para responder essa investiga??o foi por meio de leituras de trabalhos j? realizados, pesquisas de campo nas salinas e em ?rg?o p?blicos, a utiliza??o de fotografias, question?rios e entrevistas. A busca de dados sobre a produ??o salineira, sua movimenta??o e comercializa??o foi umas das etapas do caminho metodol?gico. O resultado dessa pesquisa foi ? percep??o da din?mica da atividade salineira e os usos imprimidos no territ?rio no munic?pio de Macau/RN, bem como no estado do Rio Grande do Norte no per?odo hist?rico atual.

No. of bitstreams: 1 ValdembergAAS.pdf: 4975019 bytes, checksum: f75f416655ac17172121b061a2d7e7f8 (MD5) Previous issue date: 2008-10-10 / This study was developed in the northern coast of the city of Macau, a total area of 88,52 km?, located in the State of Rio Grande do Norte. It presents relatively plain surface, with interlaced of streams and gamboas, characterized by contributions of oceanic water, flooding areas of swamps. Altogether, the climatic and topographical conditions provide an ideal environment for the development of saline activity. Inserted in the geologic context of the Potiguar Basin, the region presents favorable conditions for the production of hydro-carbons. It still presents natural conditions for shrimp breeding and artisanal fishing. This work analyzes the transformations occurred in the land use, using air photographs of 1978, Landsat 5 ETM Images of 1988, 1998 and 2008. A secular analyzes was carried through the dynamics of the use of the territory and the transformations occurred in the landscape due to the increment of the productive activities. In the survey of the data for study of the area, it was verified that little alteration occurred in the 30 years. The saline activity that was present since the year of 1978 having an increase of about 5% in thirty years; the shrimp breeding activity that had its presence in the decade of 1990, presented a high growth in the land use, therefore in 1998 it presented 0.45% and currently it presents 6.59%. In the field it was observed that great areas used previously for the saline activity, today it is prepared for shrimp breeding and that the areas of petroleum exploration occupy salt mines, beaches and trays. In 1988 it presented a percentage of 0, 07% and currently it occupies 0.46%, having grown 50% in the last 10 years. Although the variation of the occupation of the area has been little expressive, shrimp breeding showed a growth of 1,200% in only 10 years. In regards to petroleum activity, there wasn t any demonstration of an increasing impact in the land use in the area of study in 26 years of exploration / Este estudo foi desenvolvido no litoral setentrional do munic?pio de Macau, localizado no Estado do Rio Grande do Norte, totalizando uma ?rea de 88,52 km?. Apresenta superf?cie relativamente plana, com entrela?ados de riachos e gamboas, caracterizada por contribui??es de ?guas oce?nicas, alagando ?reas de manguezais. Somadas ?s condi??es clim?ticas e topogr?ficas proporcionam um ambiente ideal para o desenvolvimento da atividade salineira. Inserida no contexto geol?gico da Bacia Potiguar, a regi?o apresenta condi??es favor?veis para a produ??o de hidrocarbonetos. Apresenta, ainda, condi??es naturais para a carcinicultura e pesca artesanal. Este trabalho analisa as transforma??es ocorridas no uso do solo, utilizando fotografias a?reas de 1978, Imagens Landsat 5 ETM de 1988, 1998 e 2008. Foi realizada uma an?lise temporal da din?mica do uso do territ?rio e as transforma??es ocorridas na paisagem, devido ao incremento das atividades produtivas. No levantamento dos dados para estudo da ?rea, foi verificado que pouca altera??o ocorreu nos 30 anos em tela. A atividade salineira que estava presente desde o ano de 1978, tendo um aumento aproximado de 5 % em trinta anos; a carcinicultura que teve sua presen?a na d?cada de 1990 apresentou um elevado crescimento no uso do solo, pois em 1998 apresentava 0,45% - atualmente 6,59%. No campo, observou-se que grandes ?reas utilizadas anteriormente para a atividade salineira, hoje se encontram preparadas para a carcinicultura e que as ?reas de explora??o petrol?fera ocupam salinas, praias e tabuleiros. Em 1988, ela apresentou uma porcentagem de 0,07% e atualmente ocupa 0,46%, tendo crescido 50% nos ?ltimos 10 anos. Embora a varia??o da ocupa??o da ?rea tenha sido pouco expressiva, a carcinicultura mostrou um crescimento de 1200% em apenas 10 anos. No tocante ? atividade petrol?fera, n?o houve demonstra??o de um aumento impactante no uso do solo na ?rea de estudo em 26 anos de explora??o
