我们概述了燃料特性分类系统（FCCS），该系统使土地管理者、监管机构和科学家能够创建和分类燃料床，并根据其支持火灾和消耗燃料的能力对这些燃料床进行分类。该工具的燃料床特性和火灾分类将为当前和未来的复杂模型提供输入，用于量化火灾行为、火灾效应和碳核算，并能够评估燃料处理的有效性。该系统是根据土地管理者、科学家和决策者通过6个区域研讨会收集的需求设计的。FCCS包含一组代表美国的燃料床，这些燃料床是根据科学文献、燃料照片系列、燃料数据集和专家意见汇编而成的。该系统能够对这些燃料床进行修改和增强，以代表特定的兴趣规模。然后，FCCS报告分配和计算每个现有燃料层的燃料特性，包括冠层、灌木、非木质、木质、凋落物-地衣-苔藓和枯草。最后，该系统通过计算火势对每个燃料床进行分类，火势提供了每个燃料床支持表面火灾行为、支持顶火以及为燃烧、阴燃和残余消耗提供燃料的内在能力指数。FCCS的产出正在用于国家荒地火灾排放清单，并用于编制若干国家森林的燃料床、火灾危险和处理效果图。虽然FCCS是为美国建造的，但其概念框架适用于全球。
We present an overview of the Fuel Characteristic Classification System (FCCS), a toot that enables land managers, regulators, and scientists to create and catalogue fuelbeds and to classify those fuelbeds for their capacity to support fire and consume fuels. The fuelbed characteristics and fire classification from this tool will provide inputs for current and future sophisticated models for the quantification of fire behavior, fire effects, and carbon accounting and enable assessment of fuel treatment effectiveness. The system was designed from requirements provided by land managers, scientists, and policy makers gathered through six regional workshops. The FCCS contains a set of fuelbeds representing the United States, which were compiled from scientific literature, fuels photo series, fuels data sets, and expert opinion. The system enables modification and enhancement of these fuelbeds to represent a particular scale of interest. The FCCS then reports assigned and calculated fuel characteristics for each existing fuelbed stratum including the canopy, shrubs, nonwoody, woody, litter-lichen-moss, and duff. Finally, the system classifies each fuelbed by calculating fire potentials that provide an index of the intrinsic capacity of each fuelbed to support surface fire behavior, support crown fire, and provide fuels for flaming, smoldering, and residual consumption. The FCCS outputs are being used in a national wildland fire emissions inventory and in the development of fuelbed, fire hazard, and treatment effectiveness maps on several national forests. Although the FCCS was built for the United States, the conceptual framework is applicable worldwide.
