摘要：The remote sensing images of the modern Yellow River Delta from 1976 to 2016 were collected. The average high tide line method was used to extract the coastline for 40 years. The 1996 Yellow River artificial diversion was taken as the central time point to analyze the 2 0-year coastline of the modern Yellow River Delta. Evolution characteristics, the temporal and spatial development of the Yellow River Delta and the changes in the pattern of the Laizhou Bay. The results show that: since the Yellow River was diverted to Qingshuigou, the area without the seawall protection on the bank of the Qingkou River has contracted inland as a whole, and the Qingshuigou channel area is in a state of expansion to the sea. There is a significant difference between the west bank and the south bank of Laizhou Bay. The Laizhou Bay shoreline is significantly affected by artificial buildings.
