Resumo: |
The preparation of this work is justified because of the study area the natural characteristics do not dispose of many studies how much and because of presenting a diversity of forms geomorphological and no type of mapping in scale of details of these unities, as well as the identification of the environmental systems and of the use and covering of the land in scale multistorm and presented in detail scale. The area if study is located the Northwest of the state of the Ceará, and it understands the local authorities of Barroquinha and Chaval, which meet in an environment with a diversity of sceneries of two different geological powers that is the Middle Coreaú represented by the complex Chaval Granit and for the depression from the backwoods and the Formation Fences in correspondent the marine fluvial plains,, field of movable and fixed dunes, river plain and coastal trays that are unstable environments for the human occupation. The present work has as I aim to know the environmental aspects and preparation of geomorphological mapping, of the environmental systems and of the use and covering of the land through the scale of 1:15.000 and of presentation 1:125.000, through techniques of GIS and Remote Sensing. The hard-working methodology passed of the analysis of images of high resolution and a half of the RapidEye of 2012 and Landsat 8 of 2015, through colors combination it was favoring the emphasis and the identification of the unities of relief that was used like base for the construction of the maps of the environmental systems, when there are establishing the potentiality and limitations as for the use of the land and the preparation of maps multistorm of use and covering of the land with the quantification and comparison of the unities. The considered results it went to identification and quantification of the unities of relief that will serve as dock for the identification of the predominant environmental systems in the study area, so with the identification of the types of use and occupation of the ground. The integration of the interpretation of images and the field recognition made possible the identification of the main factor responsible for the changes in the local scenery that is the man, when the produced maps are able so to serve as subsidies for the environmental projection of the ammunition breads in study. |
