美国的碳预算一直是最近科学辩论的焦点[Fan等人，1998; Pacala等人，2001; Gurney等人，2002]即使是保守的估计也表明，美国生态系统吸收了大量的碳，这主要是由于历史上的土地利用做法[霍顿等人，1999; Schimel等人，2000; Pacala等人，2001年]。在美国西部，碳封存的一个关键原因是灭火。当然，灭火也为2002年火灾季节发生的灾难性损失奠定了基础。由于灭火的影响，增加规定的燃烧和变薄，以及气候变化，火灾的增加可能会严重影响国家碳预算。在大陆范围内，一个全面的研究方法-北美碳计划（NACP）-计划量化碳交换，提高我们对贡献过程的理解[Wofsy和Harriss，2002]。
The U.S. carbon budget has been the focus of recent scientific debate [Fan et al., 1998; Pacala et al., 2001; Gurney et al., 2002] Even conservative estimates suggest that U.S. ecosystems take up a significant amount of carbon, largely as a result of historical land use practices [Houghton et al., 1999; Schimel et al.,2000; Pacala et al., 2001]. In the western United States, a key cause of carbon sequestration is fire suppression. Fire suppression, of course, also sets the stage for the catastrophic losses that are occurring during fire season 2002. Increases in fire due to the effects of fire suppression, increased prescribed burning and thinning, and climate change could significantly affect the national carbon budget. At the continental scale, a comprehensive research approach—the North American Carbon Program (NACP)—is planned to quantify carbon exchange and improve our understanding of the contributing processes [Wofsy and Harriss, 2002].
