摘　　要：闽江口内、外拦门沙是福州港通海之主要障碍。本文应用遥感分析研究其悬浮泥沙的动态。结果表明,内拦门沙的形成与演变受多种因素控制,最重要的是川石水道的分流;外拦门沙是经梅花水道合流和铁板沙过滩水流分流后川石水道远端泥沙扩散的产物。目前,外沙浅滩仍显现不稳定状态。这些结论可为闽江口拦门沙整治规划提供科学依据。The Inner Bar and Outer Bar in the Minjiang Estuary are the main barriers in the navigable channel off the Fuzhou Harbour. The formation and development of the Inner Bar has been under the control of many factors of which the distributary of the Chuanshi Channel has been the most important. The Outer Bar is product of the distant silt divergence from the confluence of the Meihua Channel and the distributary of phe currents flowing over the Teibansha Shoal. Evidences show that the Outer Bar is still in an unstable state. These initial conclusions provide the scientific basis for the harnessing project of the bars in the Minjiang Estuary.
