Zona especial de interesse ambiental Laranja Doce: evolução do uso e ocupação do solo

Abstract

The environmental diagnosis allows the identification of areas more relevant to the level of transformation of a region, being extremely significant for the establishment of measures of preservation, conservation and recovery. The objective of this work was to perform a diagnosis, through geoprocessing techniques, of the process of land use and occupation of the Special Area of Environmental Interest of Sweet Orange, located in the city of Dourados-MS, in order to characterize the evolution of the A multitemporal analysis between the years 2004 and 2016. The geoprocessing was presented as an important methodological tool for the accomplishment of this analysis, for that, it was used high resolution orbital images of the Landsat satellite treated and made available by the software Google Earth Pro, subsequently performed the work of data processing in GIS, using ArcGIS 10.3 software. The study area is characterized by a valley bottom region of part of the streams of Orange and Jaguapiru which suffers great urban and anthropic influence, where its relation with the preservation and sustainable use of environmental resources is indispensable. Thus, the analysis of the environmental aspects allowed to characterize the evolution of the land use and occupation process of the ZEIA, identifying the fragilities and the intensity of conservation of the area, where it has presented improvements in relation to the environmental quality, which can be verified by the Positive balance regarding the evolution of the areas corresponding to the "Arborea Vegetation" and "Várzea Complex" classes, concomitantly with the reduction of the "Agriculture" and "Clean Field / Pasture" classes.
