Content:In recent decades, as a result of the world population expansion, to speed up the process of industrialization, human activities on forest exacerbated the effects, coupled with the global climate change, the world forest fires happen frequently.The use of biological fire resistant tree species to create a firebreak belt can effectively prevent the fire occurrence, at the same time to increase the complexity of forest ecosystems and biodiversity. So selected fire prevention tree species for Shaoxing to Establish firebreak belt can bring forestry economic benefits and ecological benefits, also improve Shaoxing forestry development.Seven indexes (including moisture content, crude fat content, calorific value, benzene-ethanol extract, crude ash, ignition temperature, combustion rate of leaves) of fire resistant capability of18evergreen broad leaved species leaves were determined in this paper. By fuzzy clustering analysis, the results are as follows:1、The order of fire resistance ability of18species from Strong to weak is Schima superba, Dendrobenthamia hongkongensis, Manglietia insignis, Elaeocarpus decipiens, Ligustrum lucidum Ait., Michelia foveolata Merr.ex Dandy, Photinia glabra, Parakmeria lotungensis (Chun et C. Tsoong)) Michelia chapensis, Machilus thunbergii, Cinnamomun camphcra, Osmanthus fragrans, Quercus rubra L., llex cornuta Lindl, Michelia platypetala, Viburnum odoratissimum Ker-Gawl, Manglietia yuyuanensis Law and Macarosepala。2、Based on the results of fuzzy cluster analysis,8strong fire resistant ability species are screened out,such as Schima superba, Dendrobenthamia hongkongensis, Manglietia insignis, Elaeocarpus decipiens, Ligustrum lucidum Ait., Michelia foveolata Merr.ex Dandy, Photinia glabra, Parakmeria lotungensis (Chun et C. Tsoong), which appropriate in the Shaoxing region to promote.
