Don) stands in north-western Spain is presented. In this model, the initial stand conditions at any point in time are defined by three state variables (number of trees per hectare, stand basal area and dominant height), and are used to estimate total or merchantable stand volume for a given projection age. The model uses three transition functions derived with the generalized algebraic difference approach (GADA) to project the corresponding stand state variables at any particular time.

In addition, the model incorporates a function for predicting initial stand basal area, which can be used to establish the starting point for the simulation. Once the state variables are known for a specific moment, a distribution function is used to estimate the number of trees in each diameter class by recovering the parameters of the Weibull function, using the moments of first and second order of the distribution. By using a generalized height-diameter function to estimate the height of the average tree in each diameter class, combined with a taper function that uses the above predicted diameter and height, it is then possible to estimate total or merchantable stand volume[FR] Un modèle dynamique de croissance de peuplement est présenté pour Pinus radiata D. dans le nord ouest de l’Espagne. Dans ce modèle, les conditions initiales du peuplement en tout point et temps sont définies par trois variables d’état (nombre d’arbres à l’hectare, surface terrière et hauteur dominante) et sont utilisées pour estimer le volume total ou marchand du peuplement pour un âge donné. Le modèle utilise trois fonctions de transition dérivées avec une approche par différence algébrique généralisée (GADA) pour projeter les variables d’état correspondantes du peuplement à n’importe quel moment. Ces équations ont été ajustées en utilisant la méthode des variables indicatrices indépendantes de l’âge. En plus, le modèle incorpore une fonction de prédiction de la surface terrière initiale du peuplement qui peut être utilisée pour établir le point de départ de la simulation. Une fois que les variables d’état sont connues à un instant donné, une fonction de distribution est utilisée pour estimer le nombre d’arbres dans chaque classe de diamètre en récupérant les paramètres de la fonction de Weibull, en utilisant les moments de premier et de second ordre de la distribution. En utilisant une fonction généralisée hauteur-diamètre pour estimer la hauteur de l’arbre moyen de chaque classe de diamètre, combinée avec une fonction qui utilise la prédiction précédente du diamètre et de la hauteur, il est alors possible d’estimer le volume total ou marchand du peuplementSIThis study was financed by the Spanish Ministry of Education and Science; project No AGL2004-07976-C02-0BMCProduccion VegetalEscuela de Ingeniería Agraria y Forestal2007info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://annforsci.biomedcentral.com/articles/10.1051/forest:2007023http://hdl.handle.net/10612/21885reponame:BULERIA.
