摘　　要：本文报道了在福建省首次进行的应用放射性示踪法观测闽江口底沙运动的研究结果。详细叙述了放射性示踪沙的实验方法,结合水文和地质资料具体分析了实验结果,为外沙抛泥区的选择和内沙航道增深工程提供了科学依据。The Minjiang River, the largest River on the western coast of the Taiwan Strait, contributes, annually, 7.75×10~6t of silt to the Strait. This paper reports for the first time, the radioactive tracing of bottom load in the estuary of the River. 'Sc traced sand (3.7×10^(10)Bq) was launched respectively at Neisha (inner shoal) and Waisha (outer shoal). The results indicate the outward movement of the bottom load from the northwest to the southeast at Neisha and along 45°NE at Waisha. The moving speed was between 50—100m/d for the former area whereas it was slower for the latter area.
