In fast-growing forests such as Eucalyptus plantations, the correct determination of stand productivity is essential to aid decision making processes and ensure efficiency wood supply chain. past decade, advances in remote sensing computational methods have yielded new tools, techniques, technologies that led improvements forest management assessments. Our aim was estimate map basal area volume stands through integration inventory, sensing, parametric, nonparametric spatial prediction. This...
ABSTRACT Modeling of the ecological niche vegetal species is useful for understanding species-environment relationship, prediction responses to climate changes and correct reforestation programs establishment plantation’s recommendation. The objective this work was establish a model distribution four tree (Casearia sylvestris, Copaifera langsdorffii, Croton floribundus Tapirira guianensis), widely used in projects state Minas Gerais, Brazil. In addition, we analyzed relationship between...
Change detection methods are often incapable of accurately detecting changes within time series that heavily influenced by seasonal variations. Techniques for de-seasoning or apply the spatial context have been used to improve results change detection. However, few studies explored Landsat’s shortwave infrared channel (SWIR 2) discriminate between and land use/land cover (LULCC). Here, we effectiveness Operational Land Imager (OLI) spectral bands vegetation indices deforestation in highly...
This study aimed at quantifying carbon (C) and biomass stocks in shoot portion, leaf litter, roots soil within a fragment of dense savanna 'cerradão', 158.5 ha area, located Minas Gerais state. Measures were quantified using dendrometric parameters obtained during the forest inventory collection root samples. Furrows dug each 100 cm long, 50 wide deep order to collect samples depths 0-30 cm, 30-50 50-100 from layers 0-10 10-20 20-40 40-60 60-100 as well any litter surrounding surface....
ABSTRACT Reduced-impact logging is a well known practice applied in most sustainable forest management plans the Amazon. Nevertheless, there are still ways to improve operational planning process. Therefore, aim of this study was create an integer linear programming (ILP) fill knowledge gaps decision support system reduced impact explorations. The minimization harvest tree distance wood log landing assessed. Forest structure aspects, income and production were set model, as adjacency...
Resumo: O objetivo deste trabalho foi determinar a distribuição potencial de 23 espécies pioneiras no Estado Minas Gerias, além identificar as variáveis ambientais que influenciam suas distribuições. algoritmo Maxent escolhido para relacionar ocorrência às seguintes bioclimáticas: variação diurna temperatura, isotermalidade, sazonalidade da precipitação do mês mais seco, (coeficiente variação) e evapotranspiração real. Também foram avaliados índice vegetação por diferença normalizada (NDVI),...
Forest harvesting planning requires careful analysis of the variables that influence machine productivity. This information is crucial for better decision-making. Thus, we aimed to compare models predicting excavator-based grapple saw productivity in wood cutting with from environmental data, forest inventory, and operator records. We applied Stepwise linear regression, Random (RF), Artificial Neural Networks (ANN) estimate (mp). Hybrid methods were also designed perform feature selection...
Geographic Information System tools, combined with mathematical methods for complex geospatial scientific investigations, are essential environmental zoning. Among these fragility models evaluate criteria related to the physical attributes of landscape ensure multi-disciplinarity information plans used in a study. However, questions raised on priority allotted each criterion or factor within multi-criteria analysis model. In this sense, analytic hierarchy process is another model that...
Different tree diameter measuring heights are displayed in the literature, which some cases can lead to different results final estimates, if model used is not compatible with measurement height. The aim of this study was evaluate and validate equations volume biomass, adjusted by Goal Programming regression Ordinary Least Squares Method for Cerrado Sensu Stricto Campo Minas Gerais state, using information on diameters measured at 0. 10, 0.30 1.30 meters from ground level. Thus, we...
O objetivo deste estudo foi analisar a evolução da área minerada no Quadrilátero Ferrífero (QF), Minas Gerais, e quantificar coberta com vegetação florestal nativa que suprimida por esta atividade durante os últimos 26 anos. Foram utilizadas imagens TM/Landsat 5 correspondente de nos anos 1985, 1989, 2000 2011. Para cada ano análise, utilizando técnicas interpretação visual imagens, foram criados polígonos identificando delimitando as áreas mineradas. análise supressão pela mineração, 1985...
O objetivo deste trabalho foi determinar a rotação econômica de plantações eucalipto em três diferentes sítios produtivos sob condições risco. Os dados utilizados na realização do estudo são provenientes plantios equiâneos e monoclonais híbrido Eucalyptus urograndis, cedidos pela empresa Fibria Celulose. Além dos produção das áreas foram também cedidas as informações fluxo caixa. Para análise risco utilizou-se o método Monte Carlo, tendo como resultado da simulação Valor Presente Líquido...
The main purpose of this paper was to present the Forestry Routing Optimization Model (FRoM) as a version classical Vehicle Problem (VRP). This work approaches for wood logistic problems consisting simple displacement and multiple displacements trucks toward stands. FRoM encompasses both steps into one single integer mixed linear programming model, considering cranes schedule, fleet reduction, reduction overtime, half-load transportation, approaching minimum distance traveled along fixed...
http://dx.doi.org/10.5902/198050989289Os impactos gerados na paisagem após a colheita florestal em reflorestamentos são visíveis, porém, o corte raso é um processo necessário para garantir uma produção sustentada e introduzir novas tecnologias. Uma alternativa de controle utilizar restrições adjacência nos modelos matemáticos. Assim, objetivo do estudo foi avaliar capacidade da meta-heurística SA resolução matemáticos com tipo URM, observar sua ação aumento complexidade problema. O conduzido...
Eremanthus erythropappus is a commercially-important tree which has long history of exploitation in the Brazilian State Minas Gerais. The knowledge on potential geographical distribution E. therefore critical for species sustainability. Thus, aim this study was to estimate and map current future ecological niche We used Random Forests algorithm model climates scenarios. Our predictions indicate Espinhaço, Mantiqueira, Canastra mountain ranges as core areas forecast drastic reductions under...
