摘要

摘要: 海洋食物网研究是海洋生态系统研究中的重要部分。特定化合物同位素分析(CSIA)技术是一项研究海洋食物网的新技术，较测定总有机物的稳定同位素技术，为海洋食物网研究提供了更为深入和丰富的信息。通过脂肪酸、氨基酸等分子的稳定同位素特征，可以更细致更准确地了解食物网的营养结构、物质和能量的传递过程。该技术在海洋食物网研究中，特别是在海洋热液系统食物网研究之中表现出广泛的适用性。虽然特定化合物同位素分析技术仍有一些局限性有待改进，但在海洋食物网研究的应用中已经显示出很大的发展潜力。

Abstract: arine food web plays an important role in marine ecological system. Compound-specific isotope analysis (CSIA) is a new approach in this field. It provides more abundant and precise information in the studies of marine food web compared to stable isotope analysis for bulks and tissues. Stable isotopic characteristics of fatty acid and amino acid can reveal trophic structures, matter and energy flow processes of marine food webs in detail. Compound -specific isotope analysis has displayed its applicability in many fields, particularly in the study of special food web under extreme environment, such as vent system. Although there are some limitations in utilization, the new technique is very promising in future studies.
