Stand density index (SDI)

  • Mass für die Dichte einer Bestockung, das aus der Stammzahl pro ha (im LFI Bäume und Sträucher ab 12 cm Brusthöhendurchmesser [BHD]) und dem Mitteldurchmesser berechnet wird. Bei einer Kluppschwelle von 0 cm ist der SDI weitgehend unabhängig von Standortgüte, Baumartenzusammensetzung und Bestandesalter.derdf :langString
  • Measure of the density of a stocking calculated from the number of stems per hectare (in NFI trees and shrubs with a diameter at breast height [dbh] ≥12 cm) and the mean diameter. With a callipering threshold of 0 cm, the SDI is largely independent of the site quality, tree species composition and stand age.xsd :string

  • Mesure de la densité d’un boisement calculée à partir du nombre de tiges par hectare (dans l’IFN, arbres et arbustes d'au moins 12 cm de diamètre à hauteur de poitrine [DHP]) et du diamètre moyen. Pour un seuil d’inventaire fixé à 0 cm, le SDI est largement indépendant de la fertilité de la station, du mélange d’essences et de l’âge du peuplement.frrdf :langString
  • Misura della densità di un soprassuolo, calcolato in base al numero di fusti all'ettaro (nell'IFN, alberi e arbusti a partire da 12 cm di diametro a petto d'uomo [DPU]) e dal diametro medio. Per una soglia di cavallettamento di 0 cm, l'SDI è perlopiù indipendente dalla fertilità della stazione, dalla composizione delle specie arboree e dall'età del popolamento.itrdf :langString
