对我国长江口和东海海区的典型声学地层剖面图所显示的图像特征的物理本质作了分析，归纳出９个方面的主要图像特征，并指出可以分别根据其中４个特征对９类可能存在的地层的地质属性进行分类和识别．在此基础上本文讨论了应用基于概率计算的Ｂａｙｅｓ图像分类器对声学地层剖面图进行地质解释的问题．
The physical characteristics of the image features displayed by the typical acoustic stratigraphic cross-section of the Yangtze Estuary and the East China Sea are analyzed, and the main image features of nine aspects are summarized. It is pointed out that there are 9 possible features Stratigraphic geological attributes are classified and identified. On this basis, this paper discusses the application of Bayesian image classifier based on probability calculation to geologically explain the acoustic stratigraphic profile.
