全球硅酸盐岩化学风化—二氧化碳消耗定量模型研究进展
Research progress on quantitative models of chemical weathering-carbon dioxide consumption of global silicate rocks
摘要
Abstract
Silicate rocks are factors that influence the global carbon cycle as well as climate change by chemically reacting with carbon dioxide,removing atmospheric carbon dioxide and sequestering it in weathering products or ocean carbonate rocks.Quantifying the total amount of carbon dioxide consumed by weathering of global silicate rocks is key to understanding the Earth's current and past climate change.This paper systematically investigates the data sources,research methods,calculation formulas,and main in-fluencing factors of five quantitative models of chemical weathering-CO2 consumption of silicate rocks.The CO2 consumption calculated by the latest Celine model serves as a reference standard for comparing the ad-vantages,disadvantages and scope of application of each model.The existing models estimate the global carbon dioxide consumption of chemical weathering of rock silicate rocks to be 69-169 Tg/yr,in which the main parameters of each model include climate(temperature,runoff)and lithology,and the second-ary parameters include tectonic uplift,volcanism and plant interaction.Future exploration of the quantita-tive calculation of carbon dioxide consumed by the chemical weathering of silicate rocks should consider more control effects and the interconnections between factors.In addition,the use of big data analysis methods to generalize these quantitative models to the reconstruction of the palaeoclimate of the deep earth may be a future research trend.关键词
