Volume equation and volume table of pinus pinaster Ait
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 5
Abstract
Logarithmic stem volume equation based on tree height, diameter at breast height (dbh), and on both variables were determined for pinus pinaster Ait.Data were measured in kiashahr region (north of Iran, rainfall 1187 mm year-1, 37º , 26' latitude and 49º , 57'longitude), a remnant of the kiashahr plantation, on 102 sample trees which varied between 2 and 35 cm dbh and 2 and 14m height. Least relative standard error of the volume estimation by two-variable model was 10%. The best model was determined as Ln (v)= -10.996 + 1.984 Ln(d) + 1.211 Ln(h2 / h-1.3), where stem volume (V) is in cubic meters, diameter(d)is in centimeter and height is in meter.
