Unidades de paisagem e dinâmica temporal do uso e cobertura do solo na bacia hidrográfica do Rio das Pedras, Goiás, Brasil

Abstract: O objetivo deste trabalho foi avaliar a inter-relação do meio físico com a cobertura vegetal, aliada à dinâmica temporal de uso do solo, por meio das unidades de paisagem. O estudo foi aplicado na Bacia Hidrográfica do Rio das Pedras, no estado de Goiás, norteado por uma abordagem de análise integrada da paisagem. Para a definição das unidades de paisagens, foram consideradas as características geológicas, geomorfológicas, pedológicas e morfométricas da bacia. Na análise temporal de uso/cobertura do solo, fora… Show more

“…The global changes in land use are motivated mainly by the substitution of tropical forests by agriculture, pasture, and urbanization (Song et al, 2018;Mello et al, 2020). Consequently, Cerrado's vegetation cover loss also occurred through the insertion of pasture, irrigated crops, and urban expansion (Souza et al, 2021). The dynamics on the land use of the hydrographic basin of Montividiu River confirmed the predominance of farming areas that were, probably, implemented due to the characteristics of the Southwest of Goiás state: low declivities, great extensions of Latosol, climate seasonality, easy access through Highways GO 220, GO 174, and GO 184, proximity to the Metropolitan Region of Goiânia, to the federal Capital (Brasília), to the Triângulo Mineiro and São Paulo (favoring the production flow), implementing public policies of development and technological advancement Martins & Galvani, 2020;Alves et al, 2021).…”

“…was applied at a dose of 5 L ha -1 to control spontaneous vegetation. Sowing fertilization was carried out one day before sowing, according to the soil analysis results and the corn crop's expected yield, according to Souza and Lobato (2004). It was applied 30 kg ha -1 of N, 180 kg ha -1 of P 2 O 5 , and 80 kg ha -1 of K 2 O (source 04-30-16, ammonium sulfate, and potassium chloride) in the sowing furrow with a tractor seed drill.…”

“…Já Santos (2018), estudando o uso do solo do município de Anápolis para o ano de 2017, verificou que as pastagens ocupavam 37,7% do território municipal, com áreas de vegetação natural cobrindo apenas 14,66%. Souza et al (2021) observaram essa mesma tendência em análise temporal do uso do solo na bacia do Rio das Pedras, inserida nos municípios de Itaberaí, Itauçu e Taquaral de Goiás, com mais de 70% da cobertura do solo já convertida para pastagem. Já Alves et al (2020) observaram um incremento maior de agricultura em detrimento de outras classes em análise de uso do solo numa bacia hidrográfica do município de Rio Verde, onde áreas agrícolas avançaram, principalmente, sobre o que anteriormente era pastagem entre os anos 2007 e 2017.…”
