【摘要】 本文定量的研究四川省攀枝花——西昌地区不同林型的云南松林地上部分生物量及云南松林各层次可燃物的数量、类型及热值分布规律等。研究结果表明:云南松林地上部分可燃物总量为95.043t/ha,其中乔木层77.914t/ha,灌木层4.164t/ha,草本层0.104t/ha,凋落层12.860t/ha。测定了12种可燃物的发热量。计算出不同林型的云南松林燃烧时潜在能量为:草类——云南松林177.57×10¹⁰J/ha,灌木——云南松林154.56×10¹⁰J/ha,常绿栎类——云南松林167.63×10¹⁰J/ha,落叶栎类——云南松林158.74×10¹⁰J/ha,旱冬瓜——云南松林170.57×10¹⁰J/ha。更多还原

【Abstract】 Quantative researches were made on surface biomass in different types of Yunnan pine forest in the Panzhihua-Xichang areas, and on the quantity, type and caloricity distribution law of flammable substances in their varied layers. Results have shown that surface flammable substances in Yunnan pine forest totals 95. 043T/ha, of which arbor layer makes up 77. 414 T/ha, shrub layer 4. 165 T/ha, herb layer 0. 104 T/ha, and litter layer 12. 86 T/ha. Moreover, the heat output of 12 kinds of flammable substances have been determined. When different types of Yunnan pine forests are burned, their potential energy are computed as follows, grasses-Yunnan pine forest, 17757 × 10¹⁰ T/ha; shrub-Yunnan pine forest, 154.56 × 10¹⁰T/ha; evergreen oaks-Yunnan pine forest, 167.63 × 10¹⁰T/ha; deciduous oaks-Yunnan pine forest, 158.74 × 10¹⁰T/ha; and camptotheca-Yunnan pine forest, 170.57 × 10¹⁰T/ha.更多还原
