บทคัดย่อ :
Vertical stratification employing four different methods namely, profile diagram, crown depth diagram, M-w diagram and symmetric type difference diagram was carried out in the four dominant types of the dry dipterocarp forest namely : Shorea floribunda-Quercus kerrii , (s1.1, s1.2, s1.3, s1.4 and s1.5) S. obtusa-S. siamensis (s2.1, s2.2, s2.3, s2.4 and s2.5), S. obtusa-Pterocarpus macrocarpus (s3.1, s3.2, s3.3, s3.4 and s3.5) and S. siamensis, S. floribunda (s4.1, s4.2, s4.3, s4.4 and s4.5) at Sakaerat Environmental Research Station (SERS), Amphur Pak Thong Chai Changwat Nakhon Rachsima, Northeast Thailand. This investigation aims at finding the most suitable method for analyzing forest stratification. Five sample plots of 20 X 100 m2 were laid out in each dominant type. All trees over 4.5 cm in DBH contained in each plot were mapped and stem diameter at 1.3 m above the ground (DBH), total tree height (H), height of the lowest living main branch (HB) were measured.
