稳定同位素分析是示踪碳、水循环中地球化学过程的有力工具。一种特别有效的方法是采用多种同位素，其中同时评估不同化合物中的D/H、18 O/ 16 O和/或13 C/ 12 C提供了一种独特的手段来研究水和5碳同位素在不同时间和空间尺度上的耦合。在这里，我们提出了一个最新的研究进展，在我们的过程为基础的理解利用碳，氧和氢同位素，深入了解碳和水循环。我们强调了最近的技术发展和方法，它们的优势和方法上的预防措施，并举例说明了从几分钟到几个世纪10和从树叶到地球仪的范围。
Stable isotope analysis is a powerful tool for tracing biogeochemical processes in the carbon and water cycles. One particularly powerful approach is to employ multiple isotopes where the simultaneous assessment of the D/H, 18 O/ 16 O and/or 13 C/ 12 C in di ff erent compounds provide a unique means to investigate the coupling of water and 5 carbon fluxes at various temporal and spatial scales. Here, we present a research update on recent advances in our process-based understanding of the utilization of carbon, oxygen and hydrogen isotopes to lend insight into carbon and water cycling. We highlight recent technological developments and approaches, their strengths and methodological precautions with examples covering scales from minutes to centuries 10 and from the leaf to the globe.
