摘要

本文介绍了一个燃料模型的发展,该模型可以描述希腊以岩蔷薇属为主的地区的燃料状况。为了获得必要的燃料数据,在希腊西部以肉苁蓉、小花肉苁蓉和萨尔瓦多肉苁蓉为主的phryganic地区,对三十(30)块1平方米的地块进行了破坏性采样。为了开发Cistus spp.的燃料模型,现场测量补充了已公布的Cistus salvifolius的参数值。由此产生的燃料模型(高度9.44厘米)适用于描述Cistus spp.在欧洲东南部植被高度相对较低的以phryganic为主的地区。一旦开发完成,燃料模型就被输入BehavePlus系统,以产生表面火灾扩散率预测(ROSpred,m·min−1),然后将其与从Cistus覆盖区域的野火或规定烧伤中获得的21个表面火灾ROS现场观测值(ROSobs)进行比较。发现Cistus的ROS。燃料模型显著低估了实际ROS。开发了一个具有统计学意义的线性回归方程,以数学方式描述预测和观察到的ROS之间的关系。该方程可用于调整BehavePlus预测,以更准确地反映该燃料类型的真实火灾行为。

Development of a Fuel Model for Cistus spp. and Testing Its Fire Behavior Prediction Performance
This paper presents the development of a fuel model that can describe fuel situations in areas dominated by Cistus spp. (rockrose) in Greece. In order to obtain the necessary fuel data, thirty (30) 1 m2 plots were destructively sampled in phryganic areas dominated by Cistus creticus, Cistus parviflorus, and Cistus salvifolius in western Greece. To develop the fuel model for Cistus spp., field measurements were supplemented with published parameter values for Cistus salvifolius. The resulting fuel model (with a height of 9.44 cm) is suitable for describing Cistus spp.-dominated phryganic areas of relatively low vegetation height in southeastern Europe. Once developed, the fuel model was inputted into the BehavePlus system to produce surface fire rate of spread predictions (ROSpred, m·min−1), which were then compared to 21 surface fire ROS field observations (ROSobs) obtained from wildfires or prescribed burns in areas covered by Cistus spp. It was found that the ROS for the Cistus spp. fuel model significantly underpredicted the actual ROS. A statistically significant linear regression equation was developed to mathematically describe the relationship between the predicted and observed ROS. This equation can be used to adjust BehavePlus predictions to more accurately reflect the real-world fire behavior for this fuel type.
