Forest landscape restoration is a widely accepted approach to sustainable forest management. In addition to revitalizing degraded sites, forest landscape restoration can increase the supply of sustainable timber and thereby reduce logging in natural forests. The current study presents a spatial land use optimization model and utilizes a linear programming algorithm that integrates timber production and timber processing chains to meet timber demand trade-offs and timber supply. The objective is to maximize yield and profit from forest plantations under volatile timber demands. The model was parameterized for a case study in Thai Nguyen Province, Vietnam, where most forest plantations grow Acacia mangium (A. mangium). Data were obtained from field surveys on tree growth, as well as from questionnaires to collect social-economic information and determine the timber demand of local wood processing mills. The integration of land use and wood utilization approaches reduces the amount of land needed to maintain a sustainable timber supply and simultaneously leads to higher yields and profits from forest plantations. This forest management solution combines economic and timber yield aspects and promotes measures focused on economic sustainability and land resource efficiency.

区域可持续木材利用的土地利用空间优化：以越南为例

森林景观恢复是可持续森林管理的一种广泛接受的方法。除了振兴退化的土地外，恢复森林景观还可以增加可持续木材的供应，从而减少天然林的砍伐。当前的研究提出了一种空间土地利用优化模型，并利用了线性规划算法，该算法将木材生产和木材加工链整合在一起，以满足木材需求的权衡和木材供应。目标是在木材需求波动的情况下，最大限度地提高人工林的产量和利润。该模型已参数化，用于越南泰阮省的一个案例研究，该国大多数森林种植地都种植了相思木（A. mangium）。数据来自有关树木生长的实地调查以及问卷，以收集社会经济信息并确定当地木材加工厂的木材需求。土地利用和木材利用方法的整合减少了维持可持续木材供应所需的土地数量，同时还带来了人工林更高的产量和利润。该森林管理解决方案结合了经济和木材产量方面的特点，并采取了针对经济可持续性和土地资源效率的措施。
