Abstract Aboveground biomass is usually estimated using an allometric method. Diameter at breast height (DBH) one of the important variables that used in estimating aboveground biomass. There a relationship between values with size trees, DBH, tree height, crown diameter and greenness trees. In remote sensing, biophysical parameters can be derived from digital image processing trees assessed no...

For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree Diameter at Breath Height in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran ...

Based on the isometric hypothesis, belowground plant biomass (MB) should scale isometrically with aboveground biomass (MA) and the scaling exponent should not vary with environmental factors. We tested this hypothesis using a large forest biomass database collected in China. Allometric scaling functions relating MB and MA were developed for the entire database and for different groups based on ...
