抽象。稳定同位素分析是评价植物碳水关系及其对不同尺度生态地球化学过程影响的有力工具。我们对稳定同位素信号的基于过程的理解以及技术发展取得了显着进展，开辟了生态和跨学科研究的新领域。这促进了碳、氧和氢同位素应用的广泛利用，以深入了解植物碳和水循环及其与大气和土壤圈的相互作用。在这里，我们强调了植物碳和水关系的最新进展和新的研究挑战的具体领域，使用选定的例子涵盖从叶到区域尺度的尺度。此外，我们还讨论了最近的技术发展和方法的优势和局限性，并强调了稳定同位素测量前所未有的时间和空间分辨率所带来的新机遇。
Abstract. Stable isotope analysis is a powerful tool for assessing plant carbon and water relations and their impact on biogeochemical processes at different scales. Our process-based understanding of stable isotope signals, as well as technological developments, has progressed significantly, opening new frontiers in ecological and interdisciplinary research. This has promoted the broad utilisation of carbon, oxygen and hydrogen isotope applications to gain insight into plant carbon and water cycling and their interaction with the atmosphere and pedosphere. Here, we highlight specific areas of recent progress and new research challenges in plant carbon and water relations, using selected examples covering scales from the leaf to the regional scale. Further, we discuss strengths and limitations of recent technological developments and approaches and highlight new opportunities arising from unprecedented temporal and spatial resolution of stable isotope measurements.
