The abundance and isotope composition of pyrogenic carbon in tropical savannas

热带稀树草原燃烧是全球碳循环中一个重要但知之甚少的组成部分。该项目将量化热带稀树草原火灾期间热解碳（木炭、煤烟、生物炭）产生和扩散的动态。热解碳很重要，因为它可以在环境中存在数千年。因此，它既是碳的“汇”，也是有关过去环境的信息来源。该项目还将帮助验证“生物炭”作为碳封存的新工具，使人们能够更深入地了解火、人类、植被和气候之间的相互作用。

Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about past environments. The project will also assist in validating 'biochar' as a new tool for carbon sequestration, an enable a deeper understanding of the interactions between fire, humans, vegetation and climate.
