Abstract
Mangrove forests represent important landscape and ecological aspects of coastal tropical and subtropical regions of the Americas, covering the extensive area of the Brazilian territory.The state of Pernambuco has a concentration of mangroves quite significant, but several authors emphasize the processes of constant human disturbance suffered by this ecosystem surrounding the Port of Suape. This study aimed to evaluate the relationship between changes in the environment and its effects on the phenological development of mangrove vegetation along of two decades (1989, 1998, 2007 and 2011) in the area near the Port Complex Suape. Was used in evaluating a variable biophysics (LAI-Land Area Index) revealed the decrease in biomass over the years, addition of net radiation and soil heat flux present significant changes during this period. The modification of mangroves in degraded area is reflected in the modification of the various processes at the interface atmosphere-vegetation, and consequently, the microclimate of the mangrove forest, affecting ecological processes such as regeneration and plant growth. It is necessary to limit the forms of exploitation of this ecosystem, because the conversion of mangrove forests in degraded areas exposes the surface to direct sunlight altering the radiative balance.
