摘要: In this paper, we discuss historical and recent land subsidence in the Modern Yellow River Delta. Integrated analysis of leveling relevant background data, including groundwater level, oil extraction, geological structure, has revealed that displacement is driven by natural induced components acting at various depths. Since 1950s, intense settlements occurred modern estuary delta lobes. Between 2002 2008, center Dongying Guangrao exhibited a typical area with rates 28.2 64.7 mm/years, respectively. Higher magnitudes are associated withdrawals oil-gas field exploitations, which induce compaction deep clayey layer. There existed significant linear positive correlation between level elevation depression cone. The major contributor tectonic movements, while moderate sinking due to consolidation subsoil still acting.
