摘要
山间洪流是福建省福清市大丘海岸扇三角洲的沉积条件之一，波浪、潮汐和沿岸海流是改造该扇三角洲沉积的主要动力，潮差引起的海平面升降变化控制了洪流和海水之间的相互作用．大丘山间顺直小河流-海岸扇三角洲沉积环境由陆上、海岸过渡带和潮下带的前扇三角洲组成．对该区扇三角洲沉积环境和沉积特征的研究有利于古代扇三角洲研究和扇三角洲油气勘探与开发．
The sedimentary background of fan delta in coastland of Daqiu in Fujian province is intreduced. The sedimentation of fan delta was characterized by fidri water flowing from mountain. The sea wave, tide and ocean current were the important factors for the sedimentation. The change of sealevel caused fm tidal range controled the correlation of boter and seawater. The study on the sedimentation process and environmnt of fan delta in this area is availabe for studing ancient fandelta and petroleum exploration and development in fan-delta.
