摘要
以森林燃烧环为理论基础,采用常规方法,分别于1988年、1989年对福建省尤溪县林科所6年生杉木火力楠混交林的燃烧性进行了测定。结果表明:杉木火力楠混交林的林内日均湿度、地被物平均含水量,林分贮水量分别比杉木纯林高3％,7.66％,46.87％;易燃危险可燃物的数量和能量占林分生物量和总潜在能量的比率分别比杉木纯林小8.5％,3.96％。杉木火力楠混交林能够降低林分的燃烧性,为营林防火提供科学依据。
Based on the theory of forest burningglink, the combustibility of the 6-year-old chinese fir (Cuninghamia lanceolata) and macclure michelia(Michelia macclurei) mixed forest was determined in Youxi County in Fujian Province from 1988 to 1989. The results show that the daily mean moisture in the forest, moisture content of litters and the water reserves of the stand in mixed forest are 3％, 7.66％ and 46.87％ higher than that in pure stand respectively; The inflammables quantity and energy ratios of the stand biomass and total potential energy in mixed stand are 8.5％ and 3.69％ lower than that in pure stand respectively. Mixed forest can decrease the combustibility of stand, it presents a scientific basis for control and management of forest fire.
