Abstract: The analysis of current situation of forestry resources and their dynamic consumption quantity of Guangnan County,indicates that the consumption quantity of forestry resources of Guangnan County mainly come from the low-cost firewood materials in rural areas and the consumption speed is faster than that of growth.If energy structure in these places can be modulated through energy construction of adopting clean energy resources of methane,hydropower to replace firewood consumption,the low-cost consumption of energy forestry resources will be decreased so that the current forestry resources can be conserved.
