Resumo: | Conservation Units are National Environment Policy instruments that determined the creation of areas for protection and guarantee of ecosystem balance in the Brazilian territory. The Uberaba River Environmental Protection Area (APA) is a water conservation unit in the city of Uberaba - MG. It is characterized as a sustainable use conservation unit, and some highly impacting activities have been occurring in this area, leading to erosion, water eutrophication, and changes in water quality and quantity. The aims of this study were to evaluate soil losses and to diagnose areas of natural potential for erosion (PNE) using the Universal Soil Loss Equation (USLE), the Geographic Information System (GIS), and remote sensing products. Adjusted PNE was low (<100 t ha-1 year-1) in 38.72% of the APA and moderate (100-200 t ha-1 year-1) in 31.29% of the area. High (200-600 t ha-1 year-1), very high (600-1000 t ha-1 year-1), and extremely high indexes (> 1000 t ha-1 year-1) were observed in 29.99% of the APA. Estimates of soil loss due to water erosion below 5 t ha-1 year-1 represented 43.81% of the APA. Estimated losses between 5 and 10 t ha-1 year-1 occur in 12.22% of the area; from 10 to 20 t ha-1 year-1, 21.82% of the area; between 20 and 50 t ha-1 year-1,17.89% of the area; from 50 to 100 t ha-1 year-1, 3.92% of the area; and losses over 100 t ha-1 year-1 involved 0.34% of the APA. The use of geotechnology, remote sensing products, geographic information systems, and the Universal Soil Loss Equation enabled spatial identification of sites of greater and lesser potential erosion risk, which enabling the estimation of soil loss rates throughout the Uberaba River Environmental Protection Area. |

A Área de Proteção Ambiental (APA) do rio Uberaba é uma Unidade de Conservação criada com o objetivo de garantir a qualidade das águas do rio Uberaba, sendo este o manancial de abastecimento público da cidade de Uberaba - MG. É caracterizada como uma unidade de conservação de uso sustentável, e algumas atividades altamente impactantes vêm sendo realizadas na sua área, com isso, causando diversas alterações no meio, tais como erosão, eutrofização de cursos d’água e alterações na qualidade e quantidade de água. O objetivo deste estudo foi estimar as perdas de solo e diagnosticar as áreas com potencial natural de erosão (PNE) utilizando a Equação Universal de Perda de Solo (EUPS), o Sistema de Informação Geográfica (SIG) e os produtos de sensoriamento remoto. O PNE apresentou valores baixos (<100 t ha-1 ano-1) em 38,72% da APA, médios (100-200 t ha-1 ano-1) em 31,29% e os valores alto (200-600 t ha-1 ano-1), muito altos (600 -1000 t ha-1 ano-1) e extremamente altos (>1.000 t ha-1 ano-1) totalizaram 29,99% da APA. As estimativas de perda de solo pela erosão hídrica com valores abaixo de 5 t ha-1 ano-1 representam 43,81% da APA. Estimativas de perdas entre 5-10 t ha-1 ano-1 ocorrem em 12,22% da área, de 10-20 t ha-1 ano-1 em 21,82%, entre 20-50 t ha-1 ano-1 em 17,89%, 50-100 t ha-1 ano-1 em 3,92% e perdas superiores a 100 t ha-1 ano-1 em 0,34% da APA. O uso das geotecnologias e da Equação Universal de Perda de Solo possibilitou identificar espacialmente os locais em que ocorrem os maiores e os menores potenciais riscos de erosão, o que permitiu estimar as taxas de perda de solo ao longo da APA do rio Uberaba.Universidade Federal de Santa Maria2022-09-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4125910.5902/1980509841259Ciência Florestal; Vol. 32 No. 3 (2022); 1205-1226Ciência Florestal; v. 32 n. 3 (2022); 1205-12261980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/41259/48979https://periodicos.ufsm.br/cienciaflorestal/article/view/41259/50940Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSiqueira, Hygor EvangelistaPereira, Gener TadeuPissarra, Teresa Cristina TarléMartins Filho, Marcilio VieiraCampos, Carlos Alberto Araujo2022-12-29T17:18:49Zoai:ojs.pkp.sfu.ca:article/41259Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2022-12-29T17:18:49Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
