Abstract

This article describes the process of studying fuel characteristics in the deciduous dipterocarp forest. The area of ​​dipterocarp forest in Lam Nam Nan National Park Uttaradit Province. It was prepared to analyze the data for use in creating a decision-making process for burning the deciduous dipterocarp forest in the project area by collecting fuel characteristics will study the ecosystem in the forest which contains plant information plant density, relative density, relative frequency and the specific heat value of plant leaves. That used to analyze the specific heat value of the fuel that can be used as a data representative in the project area. Determining a storage area of ​​50 meters x 50 meters for storing trees and 10 meters x 10 meters for storing young wood. The leaves that had fallen on the soil surface were then taken for specific heat values and use the heat value and the relative density to analyze the specific heat value of the fuel in the project area. It was found that in the deciduous dipterocarp forest area, there were 141 trees and 176 young trees per 0.32 hectares (2 Rai) of land, and there were 12 types of plants in total. Deciduous trees had the highest relative density at 27.44 percentages, followed by Wo. has a relative density of 14.83, etc. When analyzed for the specific heat of the local fuel, it was 19.58 MJ/kg. Then the specific heat value data can be used to analyze the fire intensity from mathematical methods. Compared to the real field test, it was found that the fire intensity value from the data analysis had the error of 28 percent of the value from the real area test.
