Abstract:In this paper, the simulated burning and quantitative analysts of the combustibilityof mixed forest of Schima and conifer were studied. The results show that the apreadof ground fire and canopy fire can be separated effectively by forest belt of fireprevention; through rational planning and distribution, the forest fire spread can becontrolled and large area forest burning can be prevented form the macroscopic Pointof view. In mixed stand ,Schima become intermission type of restricted forest fireprevention network system and the combustibility of mixed stand of Schima andconifer is decreased to control forest burning.
