摘　　要：头足类在海洋食物网营养关系中占有重要地位,然而对其复杂的生活史过程,尤其是摄食生态学信息仍知之甚少.稳定同位素技术作为传统食物网科学研究方法的有力补充,可更深层次地分析头足类的摄食习性和栖息地等方面的重要信息.本文在比较分析国内外头足类摄食生态学研究方法的基础上,系统归纳总结了稳定同位素技术在头足类摄食生态学研究中的发展现状并介绍最新进展情况,着重分析稳定同位素技术在头足类生活史信息,尤其是在摄食生态学研究中的应用现状及发展前景,包括测定样品标准化、头足类生长发育过程中的食性转换和洄游分布等核心问题,以促进其在头足类生物学研究中的应用.Cephalopods play an important role in marine lood webs, however, Knowlectge about their complex life history, especially their feeding ecology, remains limited. With the rapidly in creasing use of stable isotope analysis （SIA） in ecology, it becomes a powerful tool and complement of traditional methods for investigating the trophic ecology and migration patterns of invertebrates. Here, after summarizing the current methods for trophic ecology investigation of cephalopods, appli cations of SIA in studying the trophic ecology of cephalopods were reviewed, including the key issues such as standardization of available tissues for SIA analyzing, diet shift and migration patterns of cephalopods, with the aim of advancing its application in the biology of cephalopods in the fu ture.
