Resumo: | The Rio dos Sinos Hydrographic Basin (RSHB), located in the eastern portion of the state of Rio Grande do Sul, in its 3,696 km2, covers different classes of land use and land cover. This article presents the division of the RSHB in sub-basins, with their respective percentages of Rural anthropic, Urban anthropic, Grassland and Forestry classes, aiming to relate each one of them to eleven water quality monitoring points, checked in the period between 2007 and 2013. The water analysis found that the Rural anthropic class predominates in the basin, with 54.92% of the total area, followed by the Forestry class, with 35.27%, and concluded that the best results of water quality are associated with the highest degree of conservation of the sub-basins, and the worsening in quality occurs gradually, towards its mouth, which has the greater influence of urban areas, industrial activity and agriculture. It is recommended that watercourses with degraded quality be restored and that actions be taken to preserve and maintain the natural vegetation cover in the spring areas. |

Cet article présente la division de la BHS en sous-bassins, avec leurs pourcentages respectifs de classes Anthropique rurale, Anthropique urbaine, Campestre et Forestière, dans le but de les relier à 11 points de surveillance de la qualité de l'eau, contrôlés sur la période de 2007 à 2013. L'analyse a révélé que la classe Anthropique rurale prédomine dans le bassin, avec 54,92% de la superficie totale, suivie de la classe Forestière, avec 35,27%. On en conclut que les meilleurs résultats en termes de qualité de l'eau sont associés à un plus grand degré de conservation des sous-bassins, et que la détérioration de la qualité se produit progressivement en direction de l'embouchure, où l'influence des zones urbaines, de l'activité industrielle et de l'agriculture est plus forte. Il est recommandé de restaurer les cours d'eau présentant une qualité dégradée et de mettre en œuvre des actions de préservation et de maintien de la couverture végétale naturelle des zones de source.A bacia hidrográfica do rio dos Sinos (BHS), localiza-se na porção leste do estado do Rio Grande do Sul e abrange, em seus 3.696 km2, diferentes classes de uso e cobertura do solo. Este artigo apresenta a divisão da BHS em sub-bacias, com seus respectivos percentuais de classes Antrópico rural, Antrópico urbano, Campestre e Florestal, e tem por objetivo relacioná-las a 11 pontos de monitoramento da qualidade da água, controlados no período entre 2007 a 2013. A análise constatou que a classe Antrópico rural predomina na bacia, com 54,92% da área total, seguida da classe Florestal, com 35,27%, concluindo-se que os melhores resultados da qualidade da água estão associados ao maior grau de conservação das sub-bacias, e a piora na qualidade ocorre gradualmente, em direção à foz, onde há maior influência das áreas urbanas, da atividade industrial e da agropecuária. Recomenda-se a recuperação de cursos d’água com qualidade degradada e a aplicação de ações de preservação e de manutenção da cobertura vegetal natural das áreas de nascentes.UFF2023-08-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://periodicos.uff.br/geographia/article/view/5206510.22409/GEOgraphia2023.v25i55.a52065GEOgraphia; Vol. 25 No. 55 (2023): jul./dez.GEOgraphia; Vol. 25 Núm. 55 (2023): jul./dez.GEOgraphia; v. 25 n. 55 (2023): jul./dez.2674-81261517-779310.22409/GEOgraphia2023.v25i55reponame:Revista Geographia (Niterói.
