Ground subsidence geological hazards are becoming more and more serious in North Shandong Plain, which restricts the construction of major projects and social and economic development. Based on the analysis of the distribution characteristics of Quaternary sediments, combined with the second- class leveling data and stratified subsidence scale data and the law of land subsidence, this paper reveals the mechanism and mode of land subsidence in the North Shandong Plain, which can be used as a reference for similar areas. (1) The main contributing layer of land subsidence in the North Shandong Plain is the Middle Pleistocene stratum, and the subsidence of 140~320 m stratum in Binzhou is about 62% of the total subsidence. (2) According to sedimentary facies, sedimentary origin, stratigraphic structure and driving mechanism of land subsidence, land subsidence in North Shandong Plain can be divided into three models: piedmont alluvial model, flood plain model, Yellow River flood alluvial plain model, delta alluvial model and marine plain model.
