Delimitação, avaliação das potencialidades e limitações das unidades ambientais no município de Juazeiro do Piauí, nordeste do Brasil

como subsídio ao planejamento ambiental

Abstract

Considering the importance of knowledge of landscapes, with the possibility of a rational use of natural resources, the objective of this study was to identify the geoenvironmental characteristics, to delimit and map the environmental units of the municipality of Juazeiro do Piauí, as well as to evaluate the potentialities and limitations in each mapped drive. The studied municipality is located in the Territory of Development of the Carnaubais, northeast of the state of Piauí. The methodology used in the work employed the integrated approach associated with field, laboratory and digital cartography techniques, fact that made possible the mapping of environmental units, considering top-morphological aspects. Thus, the following geoenvironmental units were mapped: Dissolved Surface in Morros /Hills and Tabular Forms of Juazeiro do Piauí, Structural Patamares of the Poti River Basin and the Poti River Basin. It should be noted that these units present distinct potentialities and limitations for the rational exploitation of natural resources, among the potentialities can be highlighted the extensive flat to soft ripples, developed soils (Latosols), low climatic severity in some stretches; while the limitations relate to areas with strong mountainous undulating relief, young soils (Littoral Neosols). The study was relevant, since it allowed to know in an integrated way the area of the municipality of Juazeiro do Piauí, contributing for the planning and the sustainable use of the same ones in the municipality.
