农田碳汇估算模型与应用研究述评

Research Review on the Estimation Models and the Applications of Cropland Carbon Sequestration

随着全球变化研究的不断深入,农田碳汇管理日益受到学术界与决策界的关注。农田作为陆地生态系统的重要组成部分,其固碳能力的发挥关系到能否降低大气CO2浓度和抑制全球变暖趋势。回顾近10多年来国内外农田碳汇估算模型与应用研究的主要进展,概述了4种代表性农田碳汇估算模型的原理、结构、参数及制备、应用案例和模型检验等技术环节,为区域、国家乃至全球尺度农田碳汇估算筛选了模型与方法。

Along with the depth of global change research, carbon sequestration of cropland has been given more and more concerns by the academic community and decision-making circles. As one of the major form of terrestrial ecosystems, cropland plays great roles in atmospheric carbon sequestration and inhibits the global warming trend. The main research progresses on the estimation models and the relevant application of cropland carbon sequestration were reviewed. The principle, structure, parameter and preparation, application case validations of four rep- resentative estimated models of cropland carbon sequestration were summarized, which provided models and methods for the estimation of cropland carbon sequestration at regional, national and global extents.
