Abstract:

Based on the analysis of stand of productive and high-quality Chinese fir plantation and the indexes of technology and economy concerned,the paper analyzed the dynamic economic effect of productive and high-quality Chinese fir plantation,expounded the influence of unit-yield,timber price and wage variation on the rate of return on invested capital by employing variable cost of timber production which related with volume,tree-high as well as diameter,and measured forest economic maturity,which supplied reliant bases for confirming the age of major harvest and the cultural object of the productive and high-quality Chinese fir plantation.

Key words: Chinese fir, Economic effect, Age of major harvest
