[Objective] The land use change and its influence on coastline change along Laizhou Bay was illustrated in order to provide land use data support for the government and relevant departments in coastline planning.[Methods] The land-use and land-cover change(LUCC) information of the coastwise area of Laizhou Bay and spatial distribution of coastlines from 1987 to 2017 was extracted, and land use degree index was calculated. Then the digital shoreline analysis system (DSAS) was used to calculate the adjacent phase change rate of coastlines. By the tool of overlay in ArcGIS, the factors which influence the change rate and length of coastlines were obtained.[Results] ① The area of aquaculture land, salt farm land and construction land had increased gradually from 1987 to 2017; and the area of inland water had increased on the whole; the area of bare land had decreased; and the area of grassland and cultivated land had increased and then decreased; the change of forest land had not been obvious. ② The land use degree had gradually become stronger, the land use degree with strong grade had changed from scattered distribution to centralized facet distribution. ③ Land use had affected the change rate of coastline in the form of reclamation of the sea. The enclosed sea and artificial making grounds within Laizhou Bay had pushed the coastlines to the sea; The coastline of the Yellow River delta had been pushed to the sea by the sedimentation of the Yellow River and the backsea movement of the coastlines had mainly been affected by seawater.[Conclusion] The land use along Laizhou Bay had changed obviously, and the degree of land use had been getting stronger. Land use affected the change rate of coastline in the form of reclamation of the sea, which made the coastline both advance to the sea and move back to the sea. Bare land and aquaculture land were the leading factors influencing coastline length from 1987 to 2005, while construction land and bare land were the leading factors influencing coastline length from 2005 to 2017.
