摘　　要：Some key terms and relevant standard related with stable isotope tech- nique were introduced, and the determination of carbon, hydrogen and oxygen, the three stable isotopes in water, as well as their isotope effect was discussed. Appli- cations and advances of stable isotopes were stated mainly from plant water source, water use efficiency, the most active water adsorption region in root system and water resources utilization differences among different species in plant communi- ty. In addition, some existing problems in investigating the plant-water relations by using stable isotope technique were put forward. In this study, we aimed to promote the sustainable development of stable isotope technique in the research of plant water utilization and in the field of ecology in China.介绍了稳定同位素的一些关键术语和相关标准,探讨了研究植物水分关系中C、H、O三种稳定同位素的确定及其同位素效应,同时主要从植物水分来源、水分利用效率、根系吸收水分最活跃区域、植物群落内不同物种水资源利用差异等几个方面阐述了稳定同位素先进技术的应用进展,最后指出稳定同位素技术在植物水分关系研究中存在的问题。旨在此文能起到抛砖引玉的作用,以此推动稳定同位素技术在我国植物水分利用研究甚至整个生态学领域研究中的可持续发展。
