Este trabalho objetivou analisar aspectos geoambientais de Caucaia, localizado no Estado do Ceará. O município vem apresentado nos últimos anos um elevado crescimento populacional, suscitando uma forte pressão sobre os recursos naturais, justificando assim a necessidade de se identificar as áreas mais e menos vulneráveis ambientalmente ao adensamento populacional, gerando com isto elementos para o planejamento territorial. Desse modo, procedeu-se a caracterização geoambiental criando os mapas de sistemas ambientais e de vulnerabilidade ambiental. Constatou-se que 21% do território têm alta vulnerabilidade à ocupação, sendo de 58% e 17%, respectivamente, os percentuais para os locais com média e baixa vulnerabilidade. Menciona-se que o planejamento territorial com base na compartimentação geoambiental surge como um importante delineador das condições organizacionais e da funcionalidade dos ambientes, tendo em vista que considera sempre suas características ambientais e sua dinâmica sócio-espacial de maneira integralizada.

This study aimed to analyze geoenvironmental aspects of the city of Caucaia, located in the state of Ceará, Brazil. The municipality has presented in recent years a high population growth, raising a strong human pressure on natural resources, thus justifying the need to identify the most and least environmentally vulnerable areas to population density, generating elements for territorial planning. Thus, we proceeded to environmental characterization creating maps of environmental systems and environmental vulnerability Caucaia, scale 1:50,000, using, for both, the geosystemic theory and the use of remote sensing products, cartographic data and fieldwork. It was verified that 21% of the territory have high vulnerability to occupation, being 58% and 17%, respectively, the percentages for areas with medium and low vulnerability. It is mentioned that the territorial planning based on geoenvironmental compartmentation emerges as important eyeliner of the organizational conditions and functionality of environments, considering their environmental characteristics and socio-spatial dynamics in the integrated form.
