林火碳排放模型研究进展

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。

Research Progress of Forest Fires Carbon Emissions Model

Fire as a disturbance factor affects the forest succession,forest biomass,forest productivity and biogeochemistry cycle.The carbon-containing greenhouse gases released by forest burning impose an important influence on global climate change.The effective estimation of the carbon-containing gases from forest fires can help find the effect of the carbon-containing gases from forest fires on global carbon cycle. This article described two forest fire carbon emissions model:one model is base on the effective fuels and the other is the carbon cycle model under fire disturbance.By comparing the two estimating methods,the development trend was laid out in terms of the estimating method of the future forest fire carbon emissions.
