Em casos em que n?o ? poss?vel fazer uso dos procedimentos convencionais devido a aus?ncia de ?rvores, as cepas restantes no local ? a ?nica fonte de informa??es que podem evidenciar o estoque volum?trico que foi colhido. Este trabalho teve como objetivos compreender a rela??o entre o di?metro de cepa e o volume total em um povoamento clonal de Eucalipto por meio do uso de equa??es volum?tricas e Redes Neurais Artificiais (RNA), a fim de contribuir com informa??es que possam subsidiar a??es de fiscaliza??o, auditorias em empresas privadas e projetos de manejo em geral. O estudo foi realizado na Fazenda Vida de propriedade da Gusa Nordeste LTDA, inserida no munic?pio de Barra do Corda, localizado na regi?o central do estado do Maranh?o. Foram instaladas 52 parcelas de 600 m? cada, distribu?das aleatoriamente em sete talh?es, implantados sob o mesmo regime de preparo de solo e com o mesmo material gen?tico, todos no espa?amento 4?3 m e idades em torno de seis anos. Em cada unidade amostral foi coletado a altura total de 15 ?rvores, sendo que cinco delas eram qualificadas como dominantes todos os indiv?duos foram mensurados os di?metros a 0,00; 0,05; 0,10; 0,15; 0,20; 0,25; 0,30 e 1,30 m do solo. Al?m disso, foram cubadas 64 ?rvores distribu?das em classes diam?tricas suficientes para representar o estrato. Ap?s os processamentos convencionais empregou-se as t?cnicas utilizando os di?metros pr?ximos ao solo, visando comparar os procedimentos convencionais com os propostos neste trabalho. Em um contexto geral, pode-se notar que quando n?o ? poss?vel realizar o invent?rio convencional e n?o se sabe o destino da madeira, empregar estimativas obtidas por equa??es volum?tricas e RNA ? uma alternativa vi?vel de se obter o prov?vel estoque que havia na ?rea, utilizando-se apenas as informa??es de di?metro da cepa. / Disserta??o (Mestrado) ?

In cases where it is not possible to use the conventional procedures, owing to the absence of trees, the remaining stumps on site is the only source of information in which can infer the stock volume was harvested. This study aims to understand the relationship between the diameter of tree stump and the total volume in a stand of clonal of Eucalyptus by the using of volumetric equations and Artificial Neural Networks (ANN), in order to contribute information that can offer support in actions of invigilate, audits of private companies and project management in general. The study was conducted in Farm Vida owned by Gusa Nordeste LTDA, inserted in the municipality of Barra do Corda, located in the central region of the state of Maranh?o. Were installed 52 plots with area 600 m?, randomly distributed into seven stands, and implanted under the same regime of soil preparation and with the same genetic material, all stands with same spacing of 4?3 m and and ages around six years. At each sample unit was registered data of total height of 15 trees, in which five of these trees were classified as dominant, and for all individuals inside of the sample units, has measured the diameters at 0,00; 0,05; 0,10; 0,15; 0,20; 0,25; 0,30 e 1,30 m relative to ground level. Further, 64 trees, into different diameter classes, were cubed. Those classes were sufficient to represent the stratum. After the conventional processing techniques, were employed techniques using variable of diameters measured near the level ground, order to compare with conventional procedures proposed in this work. In a general context it can be noted that when it is not possible to perform the inventory conventional and does not know the destination of the wood, use the estimates obtained by employing volumetric equations and ANN can be recommended as a viable alternative to obtain the probable wood stock, which was existent before to the harvest, using only set data of the stump diameter.
