一种在土地期望值基础上建立的盈亏平衡分析技术被应用于评价林分经过灾害性损失后的更新(或不更新)决策的经济效果。初期,随着林分年龄的增长,盈亏平衡点——被定义为林分必须被更新时所达到的材积损失百分率——随之上升,n年后,呈相对稳定趋势。在轮伐期的后期则下降。对更新的非正确决策损失代价的情况与之相似,当林分的实际死亡率接近盈亏平衡点时,这一代价也小。在一个给定年龄的林分中,盈亏平衡点与非正确决策的损失代价受到投资成本的强烈影响。
A breakeven analysis technique based on land expectation is applied to evaluate the economic effects of updating (or not updating) decision-making after the forest has suffered a catastrophic loss. Initially, as the stand age increased, the break-even point - defined as the percentage of volume lost that the stand had to be updated - increased accordingly and tended to be relatively stable n years later. The decline in the latter part of the rotation period. In a similar fashion to the updated incorrect decision loss cost, this cost is also small when the actual death rate in the stands approaches the breakeven point. In a given age, the cost of losing profits and losses and incorrect decisions is strongly influenced by the cost of investment.
