| 中文摘要: |
| 土壤水是水资源的重要组成部分，是连接自然界水循环的重要环节；一个地区的土壤水资源状况与当地作物生产、生态环境质量以及社会经济发展息息相关。应用稳定氢、氧同位素技术可从宏观和微观的结合上把握土壤水循环过程，阐明其相关机理；近年来这一技术有了长足进步，正在逐渐发展成为研究土壤水循环特别是探究土壤水分运移和转化规律的有效手段。在简述土壤水氢、氧同位素基本知识的基础上，从水的地球化学循环原理出发，讨论影响土壤水氢、氧同位素富集的因素，着重介绍了土壤水循环研究中的同位素技术的要点和特点，并对这一研究领域未来的发展进行了展望。 |
| 英文摘要: |
| Soil water is an important part of water resources and water cycle in nature. Moreover, the soil water condition is closely related to local crop production, eco-environmental quality and social-economic development. The soil water cycle and its mechanism can be explored by the application of stable hydrogen and oxygen isotope techniques from the both the macro and micro view. In recent years, the technology has gradually become an effective method for soil water cycle, especially for water migration and transformation. In this paper, the basic knowledge of hydrogen and oxygen isotopes in soil was systematically introduced. Then, the driving forces of hydrogen and oxygen isotope enrichment were analyzed based on the geochemical cycle of water, and the key points of isotope technique for soil water cycle were discussed. Finally, the future research was prospected. |
