硅酸盐矿物的风化、全球碳循环和气候变化之间的联系是复杂的，涉及一系列往往相互关联的构造、气候、地貌和生物因素。已知硅酸盐风化速率在地质年代中变化，越来越复杂的模型现在将这种变化与长期碳循环和气候变化联系起来。为了进一步提高建模的一个关键的研究需要更多和更好的数据集的风化和控制它的因素，作为一个贡献，我们审查的风化/碳循环系统的性质，用于了解它的证据来源，以及在量化风化和全球碳循环之间的反馈仍然存在的挑战。我们建议，增加了解地貌景观和过程的多样性，特别是风化和侵蚀之间的动态关系，将有助于更清楚地描绘风化和长期碳循环之间的联系。(C)2012爱思唯尔有限公司版权所有。
The links between the weathering of silicate minerals, the global carbon cycle and climate change are complex and involve a whole range of often inter-related tectonic, climatic, geomorphological and biological factors. Silicate weathering rates are known to have varied through geological time and increasingly sophisticated models now link such variation to the long term carbon cycle and climate change. In order to improve the modelling further one key research need is for more and better datasets on weathering and the factors that control it. As a contribution to this, we review the nature of the weathering/carbon cycle system, the sources of evidence used to understand it, and the challenges that remain in quantifying the feedbacks between weathering and the global carbon cycle. We propose that increased understanding of geomorphological diversity of landscapes and processes, and especially the dynamic relationships between weathering and erosion, will aid clearer portrayal of the links between weathering and the long term carbon cycle.
