摘　　要：对福建省福州、泉州、漳州、厦门等城市所在盆地沉积和断裂的研究表明,自漳州地区向北东和向南西各盆地起始沉积、沉积间断和全新世海侵等事件是时间上依次发生的序列沉积事件,漳州及其以北各第四纪盆地构成向南西掀斜的箕状盆地。基于上述规律性,提出了自漳州向北东和向南西依次扩展的第四纪以来地壳隆张的运动模型。分析了菲律宾板块与欧亚板块的接触关系和相互作用,认为菲律宾板块的作用是该区第四纪构造运动的主要驱动力,巴士系构造是该区地壳运动的触发构造。Study of sediments and faults in basins where the cities of Fuzhou, Quanzhou, Zhangzhou and Xiamen lie shows that the events such as initial deposition, depositional hiatuses and Holocene transgression in basins from Zhangzhou northeastward and southwestward are sequential deposition events that took place successively with time and that the Zhangzhou basin and various Quaternary basins north of it are southwest-tilted dustpan-shaped basins. According to the above-mentioned characteristics, the paper presents a model of successive crustal uplift and extension from Zhangzhou toward the northeast and southwest since the Quaternary and analyzes the contact relationships and interaction between the Philippine Sea plate and Eurasian plate. The authors propose a view that the action of the Philippine Sea plate was the main dynamic force of Quaternary tectonic movement in this area and that the Bashi structure is the trigger structure for the crustal movement in the area.
