Modelos para estimativa de volume de árvores individuais pela morfometria da copa obtida com lidar

Abstract: A estimativa volumétrica, a partir do escaneamento digital de florestas por meio do uso do LIDAR, potencializa o emprego de técnicas de manejo de precisão no planejamento da exploração nas florestas tropicais. A utilização dessa tecnologia de sensoriamento remoto permite a incorporação de variáveis da morfometria de copa, ainda pouco empregadas e menos conhecidas em decorrência da dificuldade de coleta em campo. O objeto deste estudo foi construir equações capazes de estimar o volume do fuste de árvores indivi… Show more

“…The DS is an index for trees architecture understands, defining the tendency of height growth in relation to diameter at breast height, and its competition stability (DURLO and DENARDI, 1998). The SI expresses how many times the crown diameter is greater than the DBH (diameter at breast height); the CI predicts the behavior of community in an upright position and level of occupation and light interception (DURLO and DENARDI, 1998). Canopy morphometry studies through the crown area (CA), formal of crown (FC) and crown proportion (CP), associated the crown diameter and length to other variables in the same stand (FIGUEIREDO et al, 2014).…”

Canopy morphometry studies through the crown area (CA), formal of crown (FC) and crown proportion (CP), associated the crown diameter and length to other variables in the same stand (FIGUEIREDO et al, 2014). Because it is a vital organ, normally correlated to its growth in diameter (SILVEIRA et al, 2015) and height (SANTOS et al, 2015a), these indices (e.g.…”

“…Estas relaciones no son tan conocidas en el medio forestal como lo es el volumen. Por lo tanto, la descripción y caracterización adecuada del árbol a través de la morfometría, ofrece la posibilidad de describir árboles, rodales y plantaciones, tanto para la toma de decisiones sobre el manejo silvicultural como su contribución en el monitoreo forestal (COSTA; FINGER; CUNHA, 2013;HESS et al, 2016); sobre todo cuando se plantea la necesidad de realizar podas, aclareos, estimar volúmenes individuales o emplear la morfometría de copa como respuesta a experimentos de fertilización/intensidades de poda (AGUILAR, 2005;ÁLVAREZ et al, 2013;FIGUEIREDO et al, 2014).…”
