通过利用相干目标InSAR时序分析方法，获取了沧州地区自2003年12月至2013年01月地面沉降演化状况。连续监测结果揭示了近十年来沧州地区主要沉降区带的空间运移状况，随着地下水开采控制管理，市区周边地区地面沉降趋缓，北部沉降区向青县发生运移，东部沿海保持整体轻微沉降，东光、肃宁等地独立分布的沉降中心有成片扩大的趋势。分析沉降区域与地下水位变化表明，沧州地区主要沉降区带的运移变化与深层地下水位变化基本一致。

In this work, we consider the spatial evolution and temporal changes in land subsidence in Cangzhou over the past ten years based on multi-temporal interferometric synthetic aperture radar (InSAR) data acquired between December 2003 and January 2013. Time series analysis showed that regional subsidence surrounding Cangzhou indicated an obvious trend of subsidence extending towards Qing County over the past ifve years, and that single subsidence centers such as Dongguang and Suning showed a tendency to merge into one large subsidence zone. Comparing the changes in deep water levels and subsidence indicated that subsidence in Cangzhou is mainly inlfuenced by deep groundwater exploration, and that regional subsidence changes were closely related to changes in groundwater levels.
