| 摘 要： | 森林火灾不仅破坏森林生态系统,还向大气中释放了大量含碳温室气体,影响碳循环。对林火碳释放进行有效地估算,可以更加深入了解林火对碳循环的作用。利用卫星遥感影像,分析了2010年6月大兴安岭呼中森林大火后植被指数变化,对火烧程度进行了分级,结合野外火烧迹地调查和可燃物含碳率,估算出不同火烧等级、不同植被类型林火过火面积、火烧消耗可燃物量和释放碳量。结果表明:此次大兴安岭呼中森林大火总过火面积为5 812.4hm2,消耗可燃物总量76 742.51t,释放碳34 534.13t,其中落叶松林和针阔混交林释放碳量分别为14 934.16和19 599.97t。

| Abstract: | Forest fire not only destroys the forest ecosystem,but also emits a great deal of green-house gases,and affect the carbon cycle.Estimating fire emissions can help us to further understand the fire effects on the carbon cycle.This paper analyzed the differences of the vegetation index after fire,based on satellite remote sensing image of Huzhong in Daxing'anling in June 2010,Fire intensity was classified by the changes of vegetation index after the fire.The consumed fuel loading and fire emissions were estim... |
