Abstract Large-scale silvicultural programs designed to alter forest characteristics to accomplish either financial or ecological goals often involve the extraction of significant volumes. The operational costs, and thus extend over which these programs can be applied, depend in large part on supply chain considerations and the degree to which removals can be merchandized. Forestry supply chain considerations include the spatial allocation of forest products processing facilities, the array of primary forest commodities they consume, and the transportation infrastructure. This study conducts a network analysis utilizing the location of 2543 primary forest product producers in the contiguous United States along with a national road dataset to evaluate hotspots where a better opportunity to merchandise forest products enables flexibility in forest management, and coldspots where alternatives are limited. This study establishes service areas of processing facilities for sawlogs, pulpwood, and biomass at varying haul-times and two scenarios as a function of transportation costs and constructs a Cumulative Merchantability Index (CMI) by summing the Merchantability Index values defining the current market extent. In the Short Haul scenario, 26% (61.71 million hectares) and the Long Haul scenario, 9% (21.32 million hectares) of the forests have low merchantability for all three commodities. Only 3% of forests in Short Haul and 20% forests in the Long Haul scenario have an opportunity to market all three forest commodities. Results are helpful in prioritizing differing management objectives by evaluating the potential cost saving afforded by selling forest commodities.

确定美国森林适销性限制的网络分析

摘要 旨在改变森林特征以实现经济或生态目标的大规模造林计划通常涉及大量采伐。运营成本，以及这些计划的适用范围，在很大程度上取决于供应链的考虑以及清除物可以商品化的程度。林业供应链考虑因素包括林产品加工设施的空间分配、它们消费的初级森林商品的种类以及运输基础设施。本研究利用美国毗邻地区 2543 家初级林产品生产商的位置以及国家道路数据集进行网络分析，以评估可以更好地销售林产品的机会能够实现森林管理灵活性的热点，以及替代品有限的冷点。本研究建立了锯木、纸浆木材和生物质加工设施在不同运输时间和两种情况下作为运输成本的函数的服务区域，并通过对定义当前市场范围的适销性指数值求和来构建累积适销性指数 (CMI)。在短途情景中，26%（6171 万公顷）和长途情景中，9%（2132 万公顷）的森林对所有三种商品的适销性都很低。只有 3% 的短途森林和 20% 的长途森林有机会销售所有三种森林商品。结果有助于通过评估销售森林商品所提供的潜在成本节约来确定不同管理目标的优先顺序。
