ABSTRACT Forest road network plays a key role in shortening the response time of firefighting activities. Therefore, evaluation and improvement of the ability of firefighting of the forest roads are essential. The widely used travel time criterion evaluation showed that firefighters can reach the areas of fires by walking and carrying portable fire equipment. However, the firefighting capability provided by this method is very limited. It is difficult to ensure that the fires can be controlled. This study proposed a new firefighting distance criterion (FFDC) to evaluate the actual firefighting coverage of the road network. Then, we proposed an approach that aims at mapping the optimal forest road network based on the FFDC. The results showed that the new planned forest road network increases the coverage of the study area from 37.2% to 57.95%. Moreover, to evaluate the influence on the forest environment, we further assessed the newly planned forest road network by using intensity evaluation criteria and absorption evaluation criteria, which are based on a multi-criteria evaluation (MCE). The intensity evaluation was 88.05%, and the absorption evaluation was 68.22%. The forest absorption capacity in the study area was good, and the road network had little impact on the environment.

一种提高林道网消防能力的方法

摘要 森林道路网在缩短消防活动响应时间方面发挥着关键作用。因此，对林道的消防能力进行评价和提高是十分必要的。广泛使用的旅行时间准则评估表明，消防员可以通过步行和携带便携式消防设备到达火灾区域。但是，这种方法提供的灭火能力非常有限。很难确保火势得到控制。本研究提出了一种新的消防距离标准（FFDC）来评估道路网络的实际消防覆盖范围。然后，我们提出了一种旨在基于 FFDC 映射最优森林道路网络的方法。结果表明，新规划的林道网将研究区的覆盖率从37.2%提高到57.95%。此外，为了评估对森林环境的影响，我们通过使用基于多标准评估（MCE）的强度评估标准和吸收评估标准进一步评估了新规划的林道网。强度评价为88.05%，吸收评价为68.22%。研究区森林吸收能力较好，路网对环境影响不大。
