摘要:

以南宁老虎岭松栎公益林为例,介绍了可燃物特征分类系统(FCCS)的使用方法。研究了FCCS所需数据的采集方法、输入方法和计算结果的解读,探讨了环境变量的输入对地表火行为预测值的影响。结果表明:老虎岭松栎公益林在调查期间(2013年4—5月)的反应强度和蔓延速度均很低。如果环境变得干旱,达到FCCS的D2L2水分含量阈值时,3号样地类型的公益林(28年生马尾松疏林)有高的火潜势、反应强度和蔓延速度。FCCS可以输入样地调查数据,提供的预测结果符合实际,可以用来指导森林火管理决策,识别高风险林分优先进行可燃物处理。

Abstract: The Fuel Characteristic Classification System (FCCS) was used to evaluate fire hazard of non-commercial pine-beech forests in Tiger Mountain, Nanning. The data collection, input and output for FCCS were introduced, especially the input of environmental variables and their effects on the calculation of surface fire behavior. The results showed that all the forest types were of low reaction intensity and low rate of spread during the inventory season (AprilMay, 2013). If the environment becomes dry and reaches the FCCS D2L2 moisture condition, plot 3 (an open forest of pine, 28-year-old) may have a high FCCS potential with a high reaction intensity and a high spread rate. As it can be customized with small-scale plot inventory data, FCCS may provide reliable fire hazard predictions to guide fire control decision making, identify high risk locations and prioritize fuel treatment of the locations
