Abstract A harvest scheduling model when the natural risk is not only dependent on the age of the forest stand but also on the stock density is presented in this paper. In addition, damages to human lives, human health and infrastructure caused by natural risks are incorporated. Using a conditional current value approach, the optimal thinning and rotation length conditions are determined and used for the qualitative analysis of the course of the optimal volume path under different risks. Also the impacts of external variables such as stand age, interest rate, timber price and damages to human lives etc. to the optimal harvest schedules are derived. The results and dependencies are discussed in detail and compared to findings presented in the literature.

在偶龄林分存在自然风险的情况下间伐和轮伐长度的经济分析

摘要 本文提出了一种当自然风险不仅依赖于林分年龄而且还依赖于蓄积密度时的采伐调度模型。此外，还包括自然风险对人类生命、人类健康和基础设施造成的损害。使用条件电流值方法，确定最佳细化和旋转长度条件，并用于定性分析不同风险下最佳体积路径的过程。还导出了诸如林龄、利率、木材价格和对人类生命的损害等外部变量对最佳采伐时间表的影响。详细讨论了结果和相关性，并与文献中提出的发现进行了比较。
