政府经常补贴林分,以确保稳定的木材供应或其他环境公用事业。在这种情况下,为了有效地利用公共资金,可能需要有效地选择补贴的林分。在本研究中,我们开发了一种利用林分采伐调度优化技术来确定补贴的最优林分集的方法。该方法通过数值计算确定每个林分的最小补贴和最佳森林采伐(商业间伐和砍伐)计划。此外,基于一个区域的林分可以划分为类别,每一类都大大小于森林总面积的假设,开发了一种确定补贴林分最佳选择的简单分类方法。补贴林分的确定是为了在“正常森林”条件下尽量减少政府的年度开支。最后,以日本长野县为例给出了应用实例。
Governments often subsidize forest stands to ensure a stable wood supply or other environmental utilities. In this situation, efficient forest stand selection for subsidization may be desired for efficient use of public funds. In this study, we developed a method that determines the optimal set of forest stands for subsidization using an optimization technique of stand-level forest harvest scheduling. The method numerically determines the minimal subsidy and the optimal forest harvesting (commercial thinning and clearcutting) schedule of each forest stand. Further, based on an assumption that forest stands in a region can be divided into categories such that each category is substantially smaller than the total forest area, a simple sort method for identifying the optimal selection of subsidized forest stands is developed. The subsidized forest stands are determined so that annual government expenditure is minimized under “normal forest” conditions. Finally, an application example using the case of Nagano Prefecture, Japan is presented.
