The increasing threat of forest fires on a global scale is not only a matter of concern due to the potential harm they may cause to both human and animal life but also due to their significant role in exacerbating climate change. In light of these circumstances, one might inquire as to whether forest soil can self-ignite and, if so, under what conditions and at what temperatures this phenomenon may occur. This question is being addressed in the German pilot “Fire science of wildfires and safety measures” of the EU project TREEADS, and the first results are presented below. The importance of basic research into the self-ignition of forest soil cannot be underestimated, as it provides crucial knowledge to prevent forest fires and protect human and animal health. Furthermore, mitigating the occurrence of forest fires can also play a role in reducing greenhouse gas emissions, contributing to global efforts to combat climate change. The procedure of the hot storage test is an effective means of determining whether a material can self-ignite. During the investigation of six soil samples, it was found that five of them were indeed capable of self-ignition. In addition to determining whether the material ignites, the modified hot storage test also analyzed the resulting smoke gases and measured their concentration. The research question of whether regional forest soil is capable of self-ignition can be answered with yes based on these initial tests. Further experiments are needed to determine if self-ignition causes forest fires.

通过热储存试验证明森林土壤样品的自燃

全球范围内日益严重的森林火灾威胁不仅令人担忧，因为它们可能对人类和动物生命造成潜在危害，而且还因为它们在加剧气候变化方面发挥着重要作用。鉴于这些情况，人们可能会询问森林土壤是否可以自燃，如果可以，在什么条件和温度下可能会发生这种现象。欧盟项目 TREEADS 的德国试点“野火火灾科学和安全措施”正在解决这个问题，初步结果如下。森林土壤自燃基础研究的重要性不可低估，因为它为预防森林火灾和保护人类和动物健康提供了重要知识。此外，减少森林火灾的发生还可以发挥减少温室气体排放的作用，为全球应对气候变化的努力做出贡献。热储存试验程序是确定材料是否可以自燃的有效手段。在对六个土壤样本的调查中，发现其中五个确实能够自燃。除了确定材料是否点燃外，改进的热储存测试还分析了产生的烟气并测量了其浓度。根据这些初步测试，区域森林土壤是否能够自燃的研究问题可以得到肯定的回答。需要进一步的实验来确定自燃是否会导致森林火灾。
