摘 要:利用杉木人工林标准地材料建立生长收获预估模型,根据技术经济指标采用净现值法研究经济成熟。结果表明:在现有技术经济指标的情况下,利率为5%时杉木人工林经济成熟龄为17年。若其它条件保持不变,木材价格或成本每增减20%,杉木人工林经济成熟龄将推迟或提前1年。利率对经济成熟龄的到来有显著影响,利率每增加1个百分点,经济成熟龄将提前1年。Using standards materials of Chinese fir plantations to establish Growth-Harvest Estimate Model, using net present value method to research economic maturity according to technical and economic indicator. The results show that: In existing technical and economic indicator situation, the age at economic maturity of Chinese fir plantations is 17 years when the interest rate is 5%. If other conditions maintain invariably, when the timber price or the cost fluctuates 20% every time, the age at economic maturity of Chinese fir plantations will postpone or ahead of time for 1 year. The interest rate has a significant influence on the arrival of economic mature age, every time when the interest rate increases 1%, the economical mature age will ahead of 1 year.
