Purpose of Review

Containing and controlling wildfire incidents is one of the main functions of fire management. Understanding how this can be done effectively and efficiently informs many of the preparatory activities undertaken by fire management agencies to limit the impact of wildfires. This second article within a two-part series summarizing the current understanding of wildfire suppression effectiveness details research undertaken at incident and landscape scales and discusses their motivations and implications. The series is concluded with a discussion of the major suppression effectiveness knowledge gaps at all scales with suggestions for addressing them.

Recent Findings

Research across incidents has been undertaken as case studies of specific events and economic analyses of productivity during the containment of large fires. Some recent case studies have demonstrated the benefits of fuel management for suppression effectiveness, while economic analyses have identified the contributions of different resource types to containment and found that productivity models developed using non-wildfire data grossly overpredict operational productivity. Research at the landscape scale has identified the variables important for fire outcomes, such as initial attack success and the effectiveness of fuel management programs, and has also identified the benefits of suppression policy changes using long-term datasets.

Summary

There are many ways that wildfire suppression effectiveness can be defined and measured. These depend on the scale and purpose that they are considered. Suppression effectiveness evaluation is challenging at most scales as it is can be undertaken for a range of objectives, is affected by many dynamic broad ranging variables, and because data is difficult to acquire. As a result, there are still many gaps in our understanding and new methods are required to capture the data required to fill these.

遏制和控制：在事件和整个景观中抑制野火的有效性

审查目的

遏制和控制野火事件是消防管理的主要功能之一。了解如何有效有效地做到这一点，有助于消防管理机构开展许多准备活动，以限制野火的影响。这是由两部分组成的系列文章中的第二篇文章，概述了当前对野火扑灭效果的理解，详细介绍了在事件和景观尺度上进行的研究，并讨论了其动机和含义。该系列文章的结尾是对各种规模的主要抑制效果知识差距的讨论，并提出了解决这些差距的建议。

最近的发现

已经进行了跨事件的研究，作为对特定事件的案例研究和在遏制大火期间对生产率进行的经济分析。最近的一些案例研究已经证明了燃料管理对抑制效能的好处，而经济分析已经确定了不同资源类型对遏制的贡献，并发现使用非野火数据开发的生产率模型严重高估了运营生产率。景观方面的研究已经确定了对火灾结果重要的变量，例如初始攻击成功和燃料管理程序的有效性，并且还使用长期数据集确定了抑制策略更改的好处。

概要

可以定义和度量野火抑制效果的方法有很多。这些取决于所考虑的规模和目的。抑制效果评估在大多数规模上都是具有挑战性的，因为可以针对一系列目标进行抑制效果评估，并且受到许多动态范围广泛的变量的影响，并且因为难以获取数据。结果，我们的理解仍然存在许多空白，需要新的方法来捕获填充这些数据所需的数据。
