Diagnóstico Ambiental do Corede norte, RS: Mapeamento do uso da Terra na Região Alto Uruguai e obtenção de Banco de dados Relacional de Fragmentos de Vegetação Arbórea

Abstract

Technological developments enabled the development of fieldequipment and laboratory that facilitate the production and analysis ofenvironmental data with a spatial accuracy increasing. Thus, the mappinginformation on the use and occupation of the land, among other things,has become an important tool to study the dynamics of the landscape Thisstudy was conducted in the region called Alto Uruguai Gaucho, covering31 citys belonging to this geographical space. Objective was to analyze andcharacterize the environmentally study area through the preparation ofthematic maps and letters and the structuring of a relational database, as acontribution to the organization of local environmental plans, and seek toidentify areas of native forest for the biodiversity of conservation. Themethodology involved the positioning system to field, relational mappingof hypsometry, clinografia, delineation and codification of watershed riverbasins by of Otto Pfafstetter method, classification soil according to thereport 30 of the State Department of Agriculture, mapping the areas ofpreservation and conservation, use classification and land tenure and, finally,the mapping of areas where use conflicts. As a result we obtained on aregional and municipal level, the thematic mapping multipurpose scale1:50.000. Getting the new relational database corrected hydrography andmunicipal boundaries and updated the road network.The fragments mapof arboreal vegetation presents the region as characterized by an agriculturalmatrix with a significant number of fragments that have a rate of (itypical)and have an average area of 3.86 hectares. The availability of informationobtained for both municipalities and municipal and state agencies and for the development contributes effectively involved in planning for municipalenvironmental management and municipal and regional articulated.
