摘　　要：本文着重研究长江武汉段河流的平面分布、垂向沉积结构及各地段剖面间相互关系,并用灰色理论进一步阐明了长江各桥剖面沉积厚度、粒度的接近性。认为长江武汉段地壳至少发生了三次升降运动,地壳运动在间歇性变化,此运动既具有连续的继承性又具有明显的不均一性。The paper emphasis on the study of Wahan section,Yangtze River,its fluvial characteristics,vertical sedimentary structures and relationships between different cross sections of different areas.Grey theory analysis further illustrated that all the bridge profiles of Yangtze River in Wuhan have similar sediments thickness and grain sizes.We believed that Wuhan section of Yangtze River experienced three times crustal movement at least,the intermittent crustal movement with characteristics of continued succeeding and apparent uneven.
