摘　　要：在对海岸带地貌发育主要影响因素进行讨论的基础上,根据实测数字声纳资料,对青岛海岸带近岸海区海底冲刷槽、潮流脊、侵蚀洼地、水下岸坡、潮滩、岛礁等地貌类型及次级微地貌声学特征进行了较详细的论述,通过对声图资料的精细解释,取得了对上述地貌特征的系统认识。Based on the discussion of the main developing factors of the submarine geomorphology and the real-time digital data of the side scan sonar surveying along the coast of Qingdao,this paper discusses in detail the relief type and acoustic characters of the secondary micro-relief,such as the scour channel,tidal ridge,erosion depression,underwater bank,tidal bank and insular reef rock.The systemic understanding to the above geomorphologic characteristics is given with the fine explanation of sonar images.
