Resumo: | Agroforestry systems (SAF) are important alternatives to generate income from sustainable agriculture, like the SAF in the North Coast of Rio Grande do Sul, Brazil. However, there are still few studies that use the precision agriculture or forest approach, using the spatialization of attributes of the vegetation of the SAF, this being the objective of this paper. An inventory was carried out in a silvibanan SAF located in Três Cachoeiras, RS, Brazil, and 33 sample units (su) were installed to measure tree individuals with CBH >15 cm. The su were georeferenced, locating the phytosociological parameters, which were interpolated by weighting the inverse of the distance (IDW) in the gvSIG, which together with the SAF limits gave rise to maps of spatial variability. The main species observed was juçara palm (Euterpe edulis Mart. - Family Arecaceae) with 75 individuals sampled, with relative dominance, frequency and density of 17, 22.2 and 37%, respectively, and importance of 76.2%. The variables that showed evident spatial variability were number of species, maximum diversity, the index diversity, dominance and equability, number of palm trees and bunches of green banana. In conclusion, the attributes of the SAF silvibananeiro have spatial variability and that the methodology used was adequate. |

Porém, ainda são poucos os trabalhos que utilizam a abordagem da agricultura ou floresta de precisão, com uso da espacialização de atributos da vegetação dos SAF, sendo este o objetivo desta pesquisa. Foi realizado um inventário num SAF silvibananeiro localizado em Três Cachoeiras, sendo instaladas 33 unidades amostrais (ua) para mensuração dos indivíduos arbóreos com CAP >15 cm. As ua foram georreferenciadas, localizando os parâmetros fitossociológicos, que foram interpolados por ponderação pelo inverso da distância (IDW) no gvSIG, que juntamente com os limites do SAF deram origem a mapas de variabilidade espacial. A principal espécie observada foi palmito juçara (Euterpe edulis Mart. - Família Arecaceae) com 75 indivíduos amostrados, com dominância, frequência e densidade relativas de 17, 22,2 e 37%, respectivamente, e importância de importância de 76,2 %. As variáveis que apresentaram variabilidade espacial evidente foram número de espécies, diversidade máxima, os índice de diversidade, dominância e equabilidade, número de palmiteiros e de cachos de banana verde. Conclui-se que os atributos do SAF silvibananeiro possuem variabilidade espacial e que a metodologia utilizada foi adequada.Universidade Federal de Mato Grosso2023-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicoscientificos.ufmt.br/ojs/index.php/nativa/article/view/1111110.31413/nativa.v9i1.11111Nativa; v. 9 n. 1 (2021); 44-53Nativa; Vol. 9 Núm. 1 (2021); 44-53Nativa; Vol. 9 No. 1 (2021); 44-532318-7670reponame:Nativa (Sinop)instname:Universidade Federal de Mato Grosso (UFMT)instacron:UFMTporhttps://periodicoscientificos.ufmt.br/ojs/index.php/nativa/article/view/11111/12709https://periodicoscientificos.ufmt.br/ojs/index.php/nativa/article/view/11111/12710Copyright (c) 2021 Nativahttps://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessAmaral, Lúcio de PaulaFerreira, Regiane AparecidaGelaim Vanz, MaxielMotter, CristianoRodrigues Gonçalves, André Luiz2021-03-05T18:23:57Zoai:periodicoscientificos.ufmt.br:article/11111Revistahttps://periodicoscientificos.ufmt.br/ojs/index.php/nativaPUBhttps://periodicoscientificos.ufmt.br/ojs/index.php/nativa/oai||rrmelo2@yahoo.com.br2318-76702318-7670opendoar:2021-03-05T18:23:57Nativa (Sinop) - Universidade Federal de Mato Grosso (UFMT)false |
