摘要
利用地表露头剖面和钻孔剖面资料，阐述了福建沿海晚第四纪地壳运动的特征，指出该地区晚更新世期间发生了幅度较大的下降运动，全新世以来，沿海盆地、平原和海湾继续下降，其余地区则显著上升。福建沿海的盆地、平原和海湾的形成、发育常受到北东和北西向两组断裂的控制。阐明这些地区晚第四纪的地壳运动对于研究断裂的活动性、地震预测预报以及重大工程的区域稳定性评价均有重要意义。
According to the data of the profiles of surface outcropping and bore hole,the characteristics of the late-Quaternary crustal motion in the inshore area of Fujian were expounded.And it is indicated that the descending motion with larger range had happened in this area in the late-Pleistocene, and since the Recent the basin, the plain and the gulf in the inshore area had continued to descend, but other regions of the area had ascended obviously. This result Is significant for the research on the fault activity and earthquake prediction and for the stability evaluation of important engineering region.
