摘　　要：长江三角洲由于受到河流、波浪、潮汐等多种因素的控制,发育了其特有的港湾状形态以及沉积特征,利用Google earth软件对长江三角洲不同地域的水体深度进行提取,将提取水体深度与实际地图相叠合绘制了现代长江三角洲水深等值线图,并进一步划分沉积微相,分析了各个微相的沉积特征及沉积机制与沉积模式。Yangtze River Delta has its unique shape of harbor and sedimentary features because of the control factors such as rivers,waves and tides. With the increasing of the means on deposition research,the water depth of Yangtze River Delta was extracted using Google Earth software,and the modern water depth map of Yangtze River Delta was drawn compositing with the practical map. The sedimentary microphase diagram was drawn combining with lithology of the surface sediment in this paper. The sedimentary characteristics of each phase were discussed and the deposition mechanism and deposition patterns were analyzed.
