摘　　要：在同一坡向、同一造林密度、同一抚育措施,而在不同海拔坡段条件下对生物防火林带10年生火力楠造林胸径、树高、冠幅和阻火效果进行调查。结果表明:不同海拔坡段对火力楠胸径、树高、冠幅生长有显著影响,不同海拔坡段火力楠对阻火效果明显不同。火力楠作为生物防火林带造林树种,要选择适宜的海拔坡段,以提高其生长效益、生态效益、经济效益和阻火效果。With the same slope aspect, the same planting density and the same tending measures, but with different altitudes, 10-year-old Michelia macclurei trees in the biological fire prevention forest belts were surveyed for their diameters at breast height （DBH）, heights, crovm diameters and fire retardant effects. The results showed that different altitudes had significant effects on the height, DBH and crown growth, and this tree species at different altitudes showed obviously different fire retardant effects. As the afforestation tree species for biological fire prevention forest belts, Michelia macclurei trees should be planted on the slopes with suitable altitudes to improve its growth, ecological benefits, economic benefits and fire retardant effects.
