滇东北中高海拔地区防火树种筛选

Selection of Fire Resistant Tree Species for the Middle-high Altitude Areas in Northeastern Part of Yunnan Province

通过测试、分析滇东北中高海拔地区10种植物叶和枝的相对含水率、着火点温度、粗脂肪含量、灰分含量、热值5个与抗火性相关的因子,产生叶和枝的抗火性排序.结合10种植物的生物学、生态学和造林学特性,筛选出野八角、矮杨梅为滇东北中高海拔地区的防火树种,野八角的综合防火性能优于矮杨梅.

Ten tree species were studied for their fire resistant features from the middle - high altitude areas of northeastern Yunnan Province. Combustibility related factors including the moisture content of leaves and twigs, ignition temperature, gross fat content, crude ashes content and calorific value of combustion of the tree species were tested and analyzed, and the order of fire resistant capacity of the 10 tree species was arranged. Combined with the biological, ecological and silvicultural characteristics of the 10 tree species, Illicium simonsii and Myrica nana were chosen as better fire resistant tree species in the middle - high altitude areas of northeastern Yunnan Province. It was showed that the integrated fire resistant properties of Illicium simonsii were superior to that of Myrica nana.
