概要

The objective of this paper is to review research into growth and yield modeling for two-storied plantation forests. Difficulty with modeling growth for this kind of forest, compared with pure even-aged forests, is mentioned. Then research in this field is divided into three parts and described. First, growth models and equations which were driven theoretically from biological assumptions and may be available to develop growth models for two-storied stands are reviewed. Secondly, research into methods of controlling light levels and the relationship between the growth of trees and light level beneath a canopy are reviewed. Thirdly, growth models developed for two-storied stands, especially two-storied plantation forests, are reviewed. In conclusion, some problems which are still left in this field are pointed out.
