Morfopedologia como subsídio ao planejamento ambiental do município de Caucaia, Ceará.

Abstract

The environmental diagnosis of an area provides information that contributes to a in a way more orderly development.In this context, the Morphopedological approach is highlighted, which, through the study of the relationship between soil and relief, provides subsidies for the use and occupation activities of a given area. Thus, the study area of the present study is the municipality of Caucaia, Ceará, and aims to identify the relationship between relief and soil and, using the Morphopedological approach, to direct favorable areas for urban expansion and guide to activities of use and occupation of the soil, assisting in the environmental management of this municipality. Thus, were developed charts and thematic maps in a scale of 1: 200.00, and therefore the overlaying of geomorphological and soil's charts, obtaining the morphopedological map. Moreover, the correlation with the topography and the morphology of the pedological systems were approached, considering its use, occupation and management. Thus, based on geomorphological parameters, two main areas were found: I: dissection and II: accumulation, and, therefore, the types of soils that were related to each geomorphological feature were associated. As a result of this process, the areas of greater comprehensiveness in the municipality are the "sertaneja" depression associated to the Solonetz soil (according to the World Reference Base for Soil Resources, 2015) and the pre coastal plateau associated to the Red-Yellow Acrisol and the Arenosols (according to the World Reference Base for Soil Resources, 2015). Thereby, the potentialities and limitations for anthropic use were identified and it was concluded that the pre coastal plateau compartment, although it's soil has edaphic limitations, is a more favorable place for urban growth. In this way, it was possible to conclude that the morphopedological approach, in the scale used, was effective to characterize the area and offer subsidies to direct the use and the occupation of the soil.
