在森林持续经营和考虑资金时间价值的基础上,从森林年平均货币收获量最大出发,提出了一个新的经济成熟龄计算公式,结合林分蓄积量、平均胸径、平均高、出材率和木材价格等因子模型,测算了不同立地类型的马尾松造纸原料林的经济成熟龄。分析了森林货币总收入、总支出、纯收入、年均纯收入的变化规律,探讨了木材价格、成本、利率等经济指标对马尾松造纸原料林经济成熟龄的影响。
Based on the sustainable management of forests and considering the time value of funds, a new calculation formula of economic maturity was proposed based on the maximum average annual monetary harvest of forests. Based on the calculation of stand volume, average breast diameter, average height, Timber price and other factor model, the paper calculates the economic mature age of Masson pine papermaking forest with different site types. This paper analyzes the law of forest total money income, total expenditure, net income and average annual net income, and discusses the influence of economic indicators such as timber price, cost and interest rate on the economic maturation age of Masson pine papermaking forest.
