Abstract: n this paper, using the method of multi purpose policy making, the main fire prevention tree species are screened preliminary. According to it, the fire prevention characteristics of the representative species Schima superba, Michelia macclurei and Altinggia gracilipes are compared with the inflammable species Cunninghamia lanceolata and Pinus massoniana. The results show that the fire prevention tree species have better fire prevention characteristics. Their ignition temperature is higher, their moisture content is greater, the rate of their moisture separation is faster, their activation energy is higher, and the thermal unit of their volatiles is lower. The results of principal components analysis show that ignition temperature, moisture content, the rate of moisture separation, activation energy, and the thermal unit of volatiles can be used as the main indices of judging the property of fire prevention of trees, and that the extraction matters and the crude ashes of phenethyl alcohol can be used as the supplementary indices of judgment. This paper sets forth the ways and countermeasures for the development and utilization of the main fire prevention tree species.
