摘　　要：针对目前海底底质分类要素单一造成的底质分类类别不够细致和底质信息获取效率低等问题,提出一种顾及声图纹理特征的海底底质分类方法,综合利用海底底质来源、地理等属性以及声图纹理特征等分类要素,进一步细化海底底质类别,解决了海底底质分类信息混淆或表达不充分等问题。实例数据分析表明,该分类方法克服了传统方法单一考虑底质粒度信息的缺点,可以真实反映海底底质的时空变化特性以及一定范围内的表面起伏特征,并且所包含的海底底质分类信息量更全面,从而可以为用户提供直接形象的海底底质信息。In order to solve the problems that the classification of marine sediment is not detailed enough and the efficiency of obtaining sediment information is low due to the single elements of marine sediment classification,a method of marine sediment classification considering sonogram texture features is proposed,the classification of marine sediment is further refined by comprehensively using the classification elements such as marine sediment source,geography and sonogram texture features,and the problems of confusion or insufficient expression of marine sediment classification information are solved.The analysis of the case data shows that the classification method overcomes the shortcomings of the traditional method,which only considers the sediment particle size information,and can truly reflect the temporal and spatial variation characteristics of the marine sediment and the surface fluctuation characteristics in a certain range,and it contains a more comprehensive amount of marine sediment classification information,which can directly provide marine sediment information for users.
