| 英文摘要 | The intensification of human activity in the 21st century has led to a rapid land subsidence along the Yellow River Delta coast, which threatens the region's future sustainable development. This study uses Sentinel-1A imagery acquired between April 2017 and June 2024 and the SBAS-InSAR method to obtain subsidence information for the Yellow River Delta. We quantified the natural and human factors influencing subsidence and explored the relationship between brine mining, soft soil thickness, the seasonal groundwater level fluctuation, and subsidence. The main results are as follows. The SBAS-InSAR measurements exhibited a high inversion accuracy, with an average error of +6.9 mm/yr and a median error of +8.6 mm/yr. The four major subsidence zones are all located in the brine mining area, with the subsidence rate reaching 325 mm/yr in the peak zone, indicating brine extraction is the most representative of human activity in the Yellow River Delta and plays a dominant role in subsidence. The driving factors influencing subsidence are ordered as salt fields distribution, nearshore distance, and GDP, with corresponding q-values (explanatory power) of 0.21, 0.14, and 0.07, respectively. Precipitation-driven fluctuations in shallow groundwater levels can affect ground deformation in most regions except the brine extraction area. Our findings can provide management support for subsidence control and flood prevention in the Yellow River Delta. |
