稳定同位素在湿地水文研究中的应用现状与前景

湿地水文过程对湿地形成、发育和演化起到了至关重要的作用,也是湿地保护和修复的关键。稳定同位素技术是湿地水文研究的有效工具,探讨了稳定同位素技术在湿地水资源性质与来源识别以及湿地水文循环研究等方面的应用,指出了当前应用中存在的问题,如缺乏湿地水文过程的系统性机理研究等,展望了稳定同位素在湿地水文中取样方法上的创新改进与人类干扰对湿地水文过程影响研究的应用前景。

Present Status and Perspectives of Application of Stable Isotopes in Wetland Hydrology Research

Wetland hydrological processes have played a vital role in wetland formation, development and evolution. Meanwhile it plays a key role in wetland conservation and restoration. Now, stable isotope has provided an effective tool for a deeper understanding of wetland hydrology. The applications of stable isotope in identiifcation of properties and origin of wetland water, and in studies of wetland hydrologic cycling were discussed. Current problems existing in the applications of stable isotope were identiifed, e.g. the lack of systematic studies of mechanism of wetland hydrological process. Future directions for innovation and improvement of sampling method in applications of stable isotope were proposed, including studies of impacts of human disturbance on wetland hydrology.
