Regression equation f or calculating
carbon from height for Acacia
auriculiformis
Relationship between total organic carbon (kg) and DBH (cm) along with total
height (m).
Dipterocarpus turbinatus
The regression equation for calculating total organic carbon content (kg/tree) was found Y= -23.513 +
2.403X1 + 2.302X2. Here Y represents the total organic carbon content (kg) of tree, X1 represents the
height (m) and X2 represents the DBH (cm). From the equation it implies that the total organic carbon
content is increased by 2.403 kg for per unit increase in height and 2.302 kg for per unit increase in
DBH (cm). The coefficient of determination (r 2 ) is 0.973 and the relationship was significant at
P>0.01. The result showed a strong positive correlation between Height along with DBH and total
organic carbon content of the species.
Acacia auriculiformis
The regression equation for calculating total organic carbon content (kg/tree) was found Y= - 22.214 +
3.620X1 + 2.779X2. Here Y represents the total organic carbon content (kg) of tree X1 represents the
height (m) and X2 represents the DBH (cm). From the equation it implies that the total organic carbon
content is increased by 3.602 kg for per unit increase in height and 2.779 kg per unit increase of DBH.
The coefficient of determination (r 2 ) is 0.974 and the relationship was significant at P>0.01. The result
showed a positive correlation between height along with DBH and total organic carbon content of the
species.
