The present dissertation is inserted in the environmental theme through a geographical approach of the Areas of Planning AP's 2 and 5 of the Rio de Janeiro city, located in the coastal zone, and characterized by a differentiation of areas, considering the physical aspects as well as the appropriation of space by the man. It is considered that the urban space production in the city determines pressure vectors on the environment, requiring the formulation and appropriation of methodologies suitable to an environmental integrated assessment of the coastal urban space, in a spatial perspective. The GEO Cities project methodology offers an integrated vision of social and environmental indicators associated to the so-called matrix PEIR (Pressure, State, Impact and Response). The objective of this study is to establish an urban-environmental diagnosis of the city AP's 2 and 5 based on the evaluation of the GEO Cities methodology implementation, and structuration of a base and database, promoting an integrated vision of the public politics associated to the coastal management, with emphasis towards the Municipal Coastal Management Plan (MCMP) and its instruments, allied with the Municipal Master Plan. The operation included the selection of indicators subordinated to the territory occupation and soil use vectors. Thematic maps were generated with the help of the ArcView® program, from IBGE census data, relative to the years of 1991 and 2000, as well as signatures and environmental monitoring performed with the Vista-SAGA/UFRJ® program, utilizing soil use information bases of the city, from 1992 and 2001, besides the modeling of a distinct seafronts database in the Vicon-SAGA® program, from the characterization promoted by the Coastline Intervention Plans. In relation to the PEIR cycle, the results express that the trends of urban expansion and demographic concentration observed in the AP's, as well as the changes in the soil use, show up distinct percentages of the relationship between city natural areas and occupied areas. The AP 2, despite the stagnation of population growth in almost all its extension, counts with urban saturation in valued places, beyond areas of irregular occupation growth; the impacts are livened up through corrective actions, in its majority. In AP 5, the significant environmental changes occurring, including in disorderly occupation strata, represent a challenge for the territorial order; the occupation of still unused areas must be guided, preventing the inadequate use and occupation of the ground which cause environmental impacts. The MCMP must correspond to management products and monitoring of the coastal zone, and being so, the modeling of the RJ/AP 's 2 and 5 base and database allowed the use of a potentially indicated instrument for the products generation and space tracking, in order to methodologically contribute to future actions involving the Coastal Management Information System / RJ, and subsidizing proposals for environmental planning in areas of the coastal zone.
