Dinâmica fitogeográfica do Refúgio de Vida Silvestre Mata do Junco Capela/SE

Abstract

In the present study has aimed to analyse the phytogeographic dynamic in The Refúgio de Vida Silvestre Mata do Junco (RVSMJ), located in Capela/Se district, with the main hypothesis that the current configuration of remnant forest comes from the historical construction of the society-nature relationship. For this, diverse methods and approaches was used as field studies, surveys, semi-structured interviews, and techniques of geoprocessing such as, photo-interpretation, terrain numerical model, thematic mapping, profiles of phytogeographic and using of soil, etc. The results allowed us to get the analysis correlating the phytogeographic dynamic with the geomorphology, topography and fragmentation. In this process, which we has mapped and characterized four tipologies of phytophysionomic platforms, namely, herbaceous, shrubby, arborescent and arboreal. It was also elaborated, a study of the landscapes units of RVSMJ based on correlation of the diverse thematic maps presented: soils, slope, hypsometric, climate, water resources, and specially the using of soil, geomorphology, and phytophysionomy and paths. The results show that RVSMJ is not a continuous forest along its entire length. He has different compositions phytogeographic with the presence of landscape units weakened due to the degradation and ownership of natural systems: at the top of the trays, the construction of roads, agriculture and housing; in part, by the development of erosion processes, and in the valley, by human interference that changed the characteristics of phytophysionomic composition.
