河流系统是全球生物地球化学循环的关键环节,是将陆地侵蚀物质输入海洋的主要通道。自然风化是河流水物源的主要营力,人为活动的影响使河流污染物的来源更加复杂,仅仅依靠主要离子组成不能很好的区分河流中物质的不同来源,而稳定碳、硫同位素可以示踪河流中物质的来源。本文综述了当代河流系统中碳、硫同位素的研究现状和分析方法,并对未来河流研究中碳-硫耦合循环研究进行了展望。
The river system is a key part of the global biogeochemical cycle and is the main channel for importing land-eroded substances into the ocean. Natural weathering is the main driving force of river water source. The influence of human activities makes the source of river pollutants more complicated. It is not enough to distinguish the different sources of matter in rivers simply by the main ion composition. Stable carbon and sulfur isotopes can be shown Trace the source of the material in the river. This paper summarizes the current research status and analysis methods of carbon and sulfur isotopes in contemporary river systems and prospects the future carbon-sulfur coupling cycle in river research.
