ANALISE MULTICRITERIAL APLICADO NA DEFINICAO DE AREAS PRIORITARIAS AO USO AGRICOLA DA TERRA DA BACIA DO RIO CAPIVARA, BOTUCATU, SP SERGIO CAMPOS 1 ; ANDREA CARDADOR FELIPE 1 ; MARCELO CAMPOS 2 E ALINE MINARELLI RECHE 1 1 Departamento de Engenharia Rural, Faculdade de Ciencias Agronomicas - FCA - UNESP - Botucatu - Sao Paulo - Brasil.  E-mail: seca@fca.unesp.br 2 Departamento de Engenharia de Biossistemas, UNESP - Tupa - Sao Paulo - Brasil.  E-mail: marcelocampos@tupa.unesp.br 1 RESUMO O uso de sistemas de informacao geografica (SIG), aliado a tecnica de analise de multicriterios, possibilita a padronizacao e a integracao de dados, que normalmente sao provenientes de diversas fontes, permitindo que se realize uma avaliacao conjunta dos mesmos, proporcionando mais eficiencia e confiabilidade no processo de tomada de decisao para promover a adequacao de uso das terras. Este estudo objetivou analisar as areas prioritarias ao uso agricola da bacia do Rio Capivara, Botucatu, SP, por meio da analise multicriterial, visando a conservacao dos recursos hidricos.  Os resultados mostraram que o Sistema de Informacao Geografica Idrisi Selva aliado a tecnica de analise de multicriterios e ao metodo de combinacao linear ponderada mostrou ser uma ferramenta eficiente na combinacao dos diferentes criterios, permitindo a determinacao da adequacao do uso agricola das terras de forma menos subjetiva. Os criterios ambientais mostraram-se adequados para a combinacao e analise multicriterial, permitindo a elaboracao do mapa das classes de adequacao ao uso agricola, podendo ser util para o planejamento regional e nas tomadas de decisoes pelos orgaos publicos e agentes ambientais, pois o metodo leva em consideracao o uso da terra racional e permitindo a conservacao dos recursos hidricos.

ANALYSIS MULTICRITERIA APPLIED IN THE DEFINITION OF PRIORITY AREAS FOR USE OF AGRICULTURAL LAND RIVER BASIN CAPIVARA, BOTUCATU, SP 2 ABSTRACT The use of geographic information systems (GIS), combined with advanced analysis technique, enables the standardization and data integration, which are usually from different sources, allowing you to conduct a joint evaluation of the same, providing more efficiency and reliability in the decision-making process to promote the adequacy of land use. This study aimed to analyze the priority areas of the basin agricultural use of the Capivara River, Botucatu, SP, through multicriterial analysis, aiming at conservation of water resources. The results showed that the Geographic Information System Idrisi Selva combined with advanced analysis technique and the weighted linear combination method proved to be an effective tool in the combination of different criteria, allowing the determination of the adequacy of agricultural land use less subjective way. Environmental criteria were shown to be suitable for the combination and multi-criteria analysis, allowing the preparation of the statement of suitability classes for agricultural use and can be useful for regional planning and decision-making by public bodies and environmental agents because the method takes into account the rational use of land and allowing the conservation of hydrics resources.
