Abstract: The productivity of various forest zones and the influential factors on its production were studied. The result showed that there are significant differences among these forest zones, of which the highest production occurs in the tropical mountain rain forest while the evergreen monsoon forest is lower and the least production appears in the dwarf mountainous woodland. No significant difference of production was detected between forest types within the same forest zone, where the tree form has no great variance as the natural forest has reached its mature stage. Therefore the major influential factors on the total production are mean diameter, tree height and density of stands.It is owing to younger age of the secondary forest stand so that the production at present is low but it will obtain high production if better care of management should be taken, its wide range of area is a resource of reserve forest which should not be neglected. In order to promote its mature earlier intensive management must be taken.
