The increase of the urban population at the expense of the rural population, the inhabitants of the cities carry out several transformations in this environment, aiming to maximize their structural comfort. In this context, urban green areas are highly impacted and their quality and quantity are affected. This research aims to define potential areas for the implementation of ecological corridors with the help of the following elements: land use and cover, street layout, hydrography, slope, vegetation fragments and protection areas. Therefore, the aim of this study was to cartographically model the continuity and discontinuity of urban green areas of the Ribeirão Anicuns Watershed, in order to assess the spatial configuration of ecological corridors in the geographic landscape. The methodological procedures included satellite image data processing, geospatial data elaboration and analysis, landscape metrics, and map algebra. The data were prepared with the aid of the Geographic Information System - GIS and data obtained from government databases available such as Goiânia City Hall, IBGE and Civil Defense. The results of this research indicate high fragmentation of vegetation in the Ribeirão Anicuns watershed, where 6,260 out of 6,504 fragments are smaller than 1 ha, representing very small polygons. However, there are 7 large fragments (>40 ha) in the watershed that represents interesting area for the implementation of connections between nearby fragments. It is evident that the characteristic of agriculture and pasture uses, still prevalent in the western region of the watershed, has resulted in this area presenting the highest number of areas favorable to the implementation of an ecological corridor. he Jardim Botânico Park, characterized by its large remaining vegetation, the proximity to other parks, and recorded hydrological imbalances in its proximity, such as flood points, has been identified as a priority connection area for the implementation of ecological corridors. This action aims to revitalize APPs and improve environmental quality in the region.
