The present research looks at the Cotijuba Island, Belém / PA, located in the island region of
the municipality of Belém. The study turns to the geoenvironmental theme from the
integrated analysis of the landscape. The choice of this study area is justified, because in the
last decades Cotijuba has undergone a rampant urbanization process, with irrational use of
its resources, generating deforestation for the extraction of wood and removal of sand for
civil construction. Thus, we sought to map the geoenvironmental units of Cotijuba Island,
based on a survey of the elements that make up the landscape. The methodology followed
the following steps: Bibliographic survey that enabled the survey of concepts that were
guiding factors for the development of the research, Field study that allowed the survey of
data and analyzes that are only possible with the measurement in loco, and Laboratory study
that was essential to the development of the research, using techniques of remote sensing
and geoprocessing that linked to the GIS allowed the making of all cartographic products
presented in the research. For the mapping of land use and land cover classes, the Envi 5.1
software was used for supervised classification, extracting a Kappa index of 0.96. For the
study of landscape metrics of forest fragments, the software arcgis 10.1 was used from the
extension Partch Analyzes. In both procedures, the Sentinel-2 satellite image from the year
2018 was used. For the production of the MDEs, the Alos Palsar radar image was used,
which allowed the analysis of the island's altimetry and slope. The mapping of the variables:
geology, geomorphology and pedology, were carried out using information collected in the
field and analysis of the results obtained from the products made in the Sentinel-2 and Alos
Palsar image, based on Florenzano's remote sensing techniques methodology ( 2007). In
view of this, the mapping of the Five Geoenvironmental Units of Cotijuba Island was made,
highlighting their general characteristics. The results showed that Cotijuba needs a
Management and Management plan on a municipal scale aimed at conserving natural
resources and promoting the generation of jobs and income for the local community. In this
sense, it is expected that the products raised here will serve as subsidies for them. Thus,
ecotourism and the implementation of ecological corridors are suggested as measures to
mitigate the problems presented here.
