项目摘要

Determining the fate of CO2 has important consequences to the environment. Forests, particularly in the wet tropics may be very large carbon sinks. Recent evidence suggests that the Amazon may be a net sink of atmospheric CO2, storing 1-9 Mg C / ha/ yr. This project seeks to understand the role of CO2 outgassing, or evasion, from the Amazon River system in the carbon cycle of this important mosit tropical forest ecosystem. The working hypothesis of this research is that CO2 evasion returns as much carbon to the atmosphere as is sequestered in upland forests on an interannual basis. Export of organic material from upland forests to fluvial environments is the primary source of carbon that is eventually respired in rivers and evaded as CO2. The field work associated with this project will samplecharacteristic sub-basins of the Amazon to determine the spatial and temporal variation in CO emission. The 3-year project will be a joint effort between researchers at the University of Washington and the Centro de Energia Nuclear na Agricultura and will model whole ecosystem carbon flux of the Amazon River system.
确定二氧化碳的去向对环境有重要影响。森林,特别是在潮湿的热带地区,可能是非常大的碳汇。最近的证据表明,亚马逊河可能是大气CO2的净汇,每年每公顷储存1-9毫克碳。该项目旨在了解亚马逊河系统在这一重要的热带森林生态系统的碳循环中CO2释放或逃逸的作用。这项研究的工作假设是,CO2逃逸返回大气中的碳与高地森林中的碳一样多。从高地森林向河流环境输出的有机物质是碳的主要来源,这些碳最终在河流中呼吸并作为CO2逃逸。与该项目相关的实地工作将对亚马逊河流域的特征子流域进行采样,以确定CO排放的空间和时间变化。这个为期3年的项目将是华盛顿大学和核能源中心的研究人员的共同努力,并将模拟亚马逊河系统的整个生态系统碳通量。
