Stable isotope analysis has been widely used in marine food web studies. An appropriate isotopic baseline is essential for calculating diet or trophic position of marine organisms when using stable isotopic data. This paper provided an overview of the selection of isotopic baselines for four ty-pical marine ecosystems, i.e. estuary and bay, neritic zone, oceanic zone, and deep sea. The interferential factors of baseline selection and the significance of compound specific stable isotope in minimizing the effects of temporal-spatial variations of isotopic baseline were summarized, and the issues needed to be solved in this field and several directions for further research were presented. It would provide a beneficial reference for further research on stable isotope ecology in marine ecosystems.
稳定同位素分析已广泛应用于海洋食物网研究。在使用稳定同位素数据计算海洋生物的饮食或营养级时，合适的同位素基线至关重要。本文概述了四种典型海洋生态系统，即河口和海湾、浅海区域、大洋区域和深海的同位素基线选择。总结了基线选择的干扰因素以及化合物特异性稳定同位素在最小化同位素基线时空变化影响方面的意义，并提出了该领域需要解决的问题和几个进一步研究的方向。这将为海洋生态系统中稳定同位素生态学的进一步研究提供有益的参考。
