RESUMO:

The satellite images have been used to map, monitor and quantify the quality of natural resource. The detailed mapping of mangrove vegetation is an increasing demand because it is an important instrument of knowledge, maintenance and management of the mangrove ecosystem in relation to changes caused by anthropic actions and/or natural activities to global changes. This work combined multispectral data from the visible and near infrared of the LANDSAT-8 system with Monospectral data from RADARSAT-2, combined with hyperspectral data of the spectroradiometry and Vegetation Index in the segmentation and classification of some mangroves in the Northeast of Brazil, taking into account the diversity of environments present in the total area of the study. As the final result of the segmentation and classification process, we calculate that the mangroves in the study area occupy a total area of approximately 5.392ha. The species R. mangle is the dominant species, totaling an area of 3,350 ha, representing 62.13% of the total area, of this total about 2,861 ha are occupied by R. mangle I (size and conventional densification), representing 53.06% of the total area; 489 ha for structural phyto condition R. mangle II (short stature and very dense), about 9.07% of the total area; mixed regions of species or transition between them occupy area of 1092 ha, about 20.25% of total area, then the specie A. schaueriana occupying an area of 950 ha, about 17.62% of the total area. This study met the expectations to get the greater efficiency in the spatial lifting for monitoring the quality of this highly sensitive ecosystem on the environmental changes: as support their preservation and transformation into a Clean Development Mechanism Project. For such, was made the estimation of trapped CO2 in mangrove forests belonging to Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão (RDSEPT) by Indirect Method nondestructive. The total estimates on the mean of trapped CO2 in each hectare occupied by the species R. mangle is 39.93t, L. schaueriana is 28.47t and the regions of mixed species is 34.20t. It is estimated that the total quantification of trapped CO2 in the RDSEPT is 17156.51t. By the obtained values, we realized that the values of mangrove in the RDSEPT in general have a great potential to generate biomass and consequently imprison CO2. It is able to generate a valuable financial opportunity, justifying the preservation of this ecosystem.
