Fires are commonly used as part of the livelihood of local people in Thailand. However, population growth is causing serious problems with agricultural expansion, forest encroachment, and illegal settlement in protected areas. Human activities are causing fires in deciduous forests increasingly frequently. Understanding the fuel characteristics and fire behavior in mixed deciduous forest areas with different fire frequencies in Doi Suthep-Pui National Park will help in developing a suitable fire management plan for this area. Twenty quadrats, each 1 × 1 m, were used to collect data regarding fuel characteristics, and 50 × 50 m quadrats were used to study fire behavior in low and high fire-frequency areas. The fuel-load data were collected every month for a period of 1 year. The results indicated that in the two fire-frequency areas, the main fuel component in this forest type was litter (leaves). Fire consumed approximately 60–70% of the total fuel loads, and fuel recovery to the original level was predicted to take around 2 years. All the fire behavior features in the LFA and the HFA showed similar characteristics, and the fire type in both areas was defined as surface fire with low intensity, which usually occurs in deciduous forests of Thailand. The heat from the fire only affected the surface soil layer and did not cause any problems in deeper layers.

泰国北部素贴山国家公园不同失火频率混合落叶林区的燃料特性和火灾行为

火灾通常是泰国当地人生活的一部分。但是，人口增长正导致农业扩张，森林侵占和保护区非法定居等严重问题。人类活动越来越多地在落叶林中引起火灾。了解在素贴山国家公园有不同火灾频率的混合落叶森林地区的燃料特性和火灾行为，将有助于制定适合该地区的火灾管理计划。使用20个四方方体（每个1×1 m）收集有关燃料特性的数据，使用50×50 m方方体研究低火和高火频区域的火灾行为。在为期1年的每个月中收集燃油量数据。结果表明，在两个发火频率区域，这种森林类型的主要燃料成分是垃圾（叶子）。火灾消耗了大约60-70％的总燃料负荷，预计将燃料恢复到原来的水平大约需要2年。LFA和HFA的所有火灾行为特征都表现出相似的特征，并且两个地区的火灾类型都被定义为低烈度的地表火灾，通常发生在泰国的落叶林中。火灾产生的热量仅影响表层土壤，而在深层不会造成任何问题。两个地区的火灾类型都被定义为低烈度的地表火灾，通常发生在泰国的落叶林中。火灾产生的热量仅影响表层土壤，而在深层不会造成任何问题。两个地区的火灾类型都被定义为低烈度的地表火灾，通常发生在泰国的落叶林中。火灾产生的热量仅影响表层土壤，而在深层不会造成任何问题。
