Abstract: Fuelwood forest is an important kind of plantation. It is closely linked with people’s living. The author based on the idea that searched for some main local fuelwood forest trees and established multi-variable regression equation with the weight of samples and the calorific value of burning, in order to found one or some dominant species of fuelwood forest which have the maximum calorific value of burning. It provides the theory basis for selecting the appropriate plantation fuelwood trees scientifically and accurately.
