Métodos para estimativas volumétricas de Pinus patula

Abstract

O objetivo do presente estudo foi comparar diferentes métodos de estimativa volumétrica para a espécie Pinus patula. Os métodos estudados foram: fator de forma artificial, modelos volumétricos clássicos, polinômio de 5° grau e método dos dois diâmetros. As estimativas foram avaliadas por meio de: coeficiente de determinação ajustado, erro padrão da estimativa relativo e análise gráfica dos resíduos, e adicionalmente, comparadas por análise de variância ao nível de 5% de probabilidade. Essa análise demonstrou não haver diferenças significativas nas estimativas obtidas pelos métodos testados em relação aos valores paramétricos advindos da cubagem rigorosa. O método dos dois diâmetros com a utilização dos diâmetros do fuste à 1,3 m e 2 m, bem como, o modelo Schumacher & Hall tiveram os menores erros padrões da estimativa relativos e melhor desempenho na análise gráfica de resíduos, mostrando-se mais precisos que os demais estudados. Entretanto, apesar da superioridade desses dois métodos, conclui-se que todos os métodos estudados mostraram desempenho satisfatório para estimativas volumétricas em Pinus patula com 9 anos de idade.
