| 中文摘要: |
| 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。 |
| 英文摘要: |
| River system is important to global biogeochemical cycles, and land erosion is the main input channel to the ocean. Natural weathering is the main force of the provenance of substance in the water, while, the impacts of human activities make the river pollutants more complex. Relying solely on the major ion composition is not enough for distinguishing different sources of substances in the river, while stable carbon and sulfur isotopes can help to trace the source of the matters in the river. This paper reviews research and analytical methods on carbon and sulfur isotopes in the contemporary river systems, and discusses the development of the coupling between carbon and sulphur isotopes in the future. |
