根据研究方法不同的动力学特征及其运用上的差异，利用已知的水文气象资料推测海洋流场的方法可以分成 3类：①描述性方法；②热成风关系式与示踪物守恒相结合的诊断方法；③Sarki syan诊断模式及复杂动力模式。结合南海环流的工作讨论了这些方法的进展情况及在南海环流研究中的作用，并对目前利用水文气象资料推测海洋流场的研究趋势进行了分析。

Some methods for deducing circulation from hydrographic data are reviewed. These methods could be classified into three types according to their different dynamics and their different applications as follows:①description methods, the major character is only to qualitatively describe the direction of ocean circulation.②diagnostic methods which combine thermal wind relation with tracer conservation, these methods could be used to quantitatively calculate the absolute ocean geostrophic currents. Some oceanographers began to consider the ageostrophic current component by these methods, and ③Sarkisyan' s diagnostic methods and the other complicated models. Taking winds, topographic effects into account, these methods quantitatively calculate the absolute currents, which include geostrophic and ageostrophic components. In this paper, we will discuss their progress together with the South China Sea circulation. We will also analyze their developmental trends in the study of deducing ocean circulation from hydrographic data. For studying the SCS circulation, these methods which deduce the ocean circulation from the hydrographic data play a very important role in recognizing the SCS ocean circulation while the differences of the results from these methods in calculating SCS ocean circulation need to be studied further.

Key words: Hydrographic data, Sea Current, The South China Sea circulation.
