บทคัดย่อ :
Dynamic of forest trees species and canopy gap regeneration of the dry diopterocarp forest at
Sakaerat Environmental Research Station, Pak Thong Chai, Nakhon Ratchasima were investigated
during AD 1982 to AD 1984. One sample plot, 100 X 100 m2 or 1 hectare was intensively studied by
subdivide into 100 subplots (10 X 10 m2). All trees with 4.5 cm. In DBH, and over existing in 10 X 10
m2 plot were mapped, recorded and measured of their trunk diameter at 1.30 m. in height for
calculating the species diversity, relative density relative frequency, importance value index,
dispersion pattern, basal area and relative dominance. Height of the lowest living branch, total
height, position and crown diameter of trees were also measured for the analysis of the vertical
structure.
