摘　　要：利用最新测深资料绘制了泉州湾地形图、地貌图,对海岸带地形地貌特征进行了详细的分析,表明泉州湾水深为0～20m,等深线走向基本平行于海岸线,局部地形变化剧烈,地貌类型可分为潮间带地貌和海底地貌(水下岸坡),且呈滩槽(水道)相间展布的特征;认为地质构造、全新世海侵、现代水动力以及人类活动等内外营力的共同作用,控制了泉州湾海岸地形地貌的形成与演化。The coastal topography and geomorphology of the Quanzhou Bay were mapped with the latest bathymetric data.The bay is 0~20m in depth and the bathymetric lines are generally parallel to the coast with local variations.The study area can be divided to two geomorphic units of intertidal and subtidal（subaquoeus slope）zones,characterized by the alternation of shoals and channels.The origin and evolvement of the topographic and geomorphologic features in the coastal zone of the Quanzhou Bay are controlled by the joint effect of endogenetic and exogenic processes,such as geologic structure,Holocene transgression,modern hydrodynamics and human activities.
