林火作为干扰因子,影响着森林演替、森林生物量和生产力以及生物地球化学循环。森林燃烧所释放的含碳温室气体对全球气候变化具有重要影响。对森林火灾释放的含碳气体进行有效估算,可以弄清林火产生的含碳气体对全球碳循环的影响。文中介绍了2种林火碳排放模型,即基于有效可燃物模型和火干扰下碳循环模型。通过对这2种估算方法的比较,指出未来林火碳排放估算方法的发展趋势。
Forest fires as disturbance factors affect forest succession, forest biomass and productivity, and biogeochemical cycles. Carbonaceous greenhouse gases released by forest burning have a significant impact on global climate change. Effective estimation of the carbon-containing gases released by forest fires can reveal the impact of the carbon-containing gases produced by forest fires on the global carbon cycle. In this paper, two models of forest carbon emission are introduced, that is, based on the model of effective combustibles and carbon cycle under fire disturbance. Through the comparison of these two kinds of estimation methods, it points out the development trend of the future forest carbon emission estimation method.
