  1. Based on 2m contour of surveyed bathymetry from 1976 to 1999 and mean - high - tidal line distracted from remote sensing images acquired by landsat - 5 tm from 1976 to 2000 respectively, quantitative analysis about alluvion and erosion as well as the relationship between accretion of modern yellow river delta and the water and sediment discharge of yellow river is made, and the results indicate the mean - high - tidal level is more effective than 2m contour of the bathymetry. it is found that the accretion of modem yellow river delta is becoming less and less, what ' s more, erosion is even more than alluvion in some recent years. diaokou promontory has been eroded seriously since yellow river changed its course in1976
