【摘要】 本文通过拟合不同立地条件下的杉木林分生长模型,研究其数量、工艺、经济成熟,并以净现值最大的经济成熟为主,认为闽南国营林场人工杉木林分在不同立地条件下的采伐年龄可确定为:Ⅰ立地条件下为30年左右;Ⅱ立地条件下为24—28年;Ⅲ立地条件下为24年。更多还原

【Abstract】 By means of the fitting of growth models of Cunning hamia lasceola-ta stands under different site conditions, this paper studies their quantitative ma-turity, technical maturity and economic maturity,By giving priority to the eco-nomic maturity with the biggest net present value, the harvesting age of artificialC. lanceolata stands under different site conditions on state-owned forest farmsin southern Fujian may be ascertained as: about 30 years under the condition ofsite Ⅰ; 24--28 years under the condition of site Ⅱ; and 24 years under the con-dition of site Ⅲ.更多还原
