The development and application of stable isotope techniques is one of the most important progress in ecological methodologies in the 1990s. Many ecological processes are accompanied with the changes of stable isotopes ratio. According to these changes, the material circulation and energy flow of ecosystems can be followed. In recent years, many researchers introduced stable isotope techniques in soil ecology to study the soil carbon cycle and the trophic relationships between soil organisms, which greatly improved our understanding on belowground ecosystem. As for collembolan, one of the most important members of soil animals, its feeding habits and trophic position in soil ecosystem are little known. Stable isotope techniques provide a useful approach to study the food resources, trophic position, and trophic relationships of collembolan. This paper summarized the applications of stable isotope techniques in the studies of the feeding habits and trophic position of collembolan, and discussed the deficiencies and prospects of related researches.
稳定同位素技术的发展与应用是20世纪90年代生态方法学最重要的进展之一。许多生态过程都伴随着稳定同位素比率的变化。根据这些变化，可以追踪生态系统的物质循环和能量流动。近年来，许多研究人员将稳定同位素技术引入土壤生态学，以研究土壤碳循环以及土壤生物之间的营养关系，这极大地增进了我们对地下生态系统的理解。至于弹尾虫，作为土壤动物最重要的成员之一，其在土壤生态系统中的食性和营养级却鲜为人知。稳定同位素技术为研究弹尾虫的食物资源、营养级和营养关系提供了一种有用的方法。本文综述了稳定同位素技术在弹尾虫食性和营养级研究中的应用，并讨论了相关研究的不足与展望。
